What Is The Pilot Light?
The Pilot Light is the heart of your water heater, and it controls the flow of water. Essentially, it is a little blue flame that produces heat by burning petroleum gas. There would be no heat and, hence, no warm water if this flame were not present.
So, What Are The Reasons Your Water Pilot Light Keeps Going Out?
Not only will we identify the potential issues, but we will also provide you with solutions to those issues. Please take notice of the following: Check to see whether your water heater is still covered by the manufacturer’s warranty. If this is the case, it should be returned to the supplier or manufacturer for repairs or complete replacement. Precautionary measure: To begin, shut off the main gas supply valve to prevent potentially fatal gas leaks. Wait 5 minutes for the heat and gas to dissipate before continuing.
1. An Unclean Pilot Tube
It is our intention to not only identify potential issues, but to also provide you with solutions. You should keep in mind the following: Find out if the warranty on your water heater is still valid. If this is the case, it should be returned to the supplier or manufacturer for repairs or complete replacement of the product. Precautions should be taken for your safety: Remove the primary gas supply valve first to avoid potentially fatal gas leaks. Count down 5 minutes until the heat and gas have dissipated completely.
2. A Dirty Thermocouple
In the case of a water heater, the thermocouple serves as its brain. It is in charge of shutting down the gas valve when it detects that the pilot light has gone out. Because the pilot light produces an electric current, the thermocouple is activated when this current is present. It serves as a safety measure, preventing gas leaks from occurring. As a result, a filthy thermocouple might be the source of your water pilot’s inability to function properly. When a coating of filth and dust accumulates on the surface of a thermocouple, the electric current cannot reach it.
On a chilly Monday morning, there is no hot water.
To begin, shut off the main gas supply valve and allow the thermocouple to cool before proceeding.
3. A Kinked Thermocouple
As soon as you’ve finished cleaning, double-check the location of the thermocouple. Also, look to see whether it’s a little bent. The thermocouple must be placed close to the pilot light in order for it to receive heat and activate the gas valve. As a result of being too far away, heat will not be received and an electric current will not be generated. The thermocouple will determine that the pilot light has been turned out and will seal the valve, cutting off the gas supply to the house. The answer is as follows: First, turn off the gas and turn off your heater, and then wait for the thermocouple to cool down before proceeding.
You’ll have to bend or straighten the thermocouple manually to get it back into position. To be effective, the blue flame must be placed close enough to the pilot light so it contacts or wraps around the blue flame.
4. A Broken Thermocouple
So, you’ve cleaned and straightened your thermocouple, but your water pilot continues to fail despite all of your efforts. You should be prepared to accept the possibility that your thermocouple is faulty at this point. Perform a diagnostic test with a multimeter on your thermocouple first, though, before you give up on it. If the voltage delivered by your thermocouple is significantly less than 20MV, then the device is almost certainly damaged and should be replaced immediately. The Solution: If the multimeter reading is near to, but not exactly at, 20MV, you can adjust the thermocouple closer to the pilot light to save energy.
5. Flex Tube Issues
Flexible tube is a long tube that links the gas controller to the burner, which contains the pilot light, thermocouple, and other components. If the flex tube is broken or blocked, the gas will not be provided to the burner for combustion to take place. Flex tube failures, on the other hand, are not as prevalent as thermocouple failures. This is why you must first inspect and ensure that your thermocouple is in excellent working order before turning your attention to the flex tube. The Solution is as follows: Straighten any kinks in the flex tubing that have formed.
Leaks in the gas line will lower the amount of gas that reaches the burner.
6. A Faulty Main Control Valve
It’s possible that you’ll never run into this situation again. We recommend that you examine the pilot tube, thermocouple, and flex tube before attempting to modify or repair this piece of equipment. The Main Control Valve Unit has a very low failure rate. However, don’t count it out just yet; it’s possible that it’s the source of your water pilot’s incessant failure. Main Control Valve: This valve is in charge of regulating the gas and water pressures of the water heater. Your water heater’s heart and soul is the thermostat.
When the gas is ignited, the main valve is fully opened, allowing for a consistent stream of gas to be provided.
The following are signs of a defective main control valve:
- A malfunctioning pilot button that does not illuminate after being pressed
- A malfunctioning control knob
- When the water temperature exceeds the stated range, you will feel extremely hot water.
The solution: There is no way around a defective main control valve in this situation. However, despite the fact that there are specialists who say they can fix this, manufacturers highly advise against it. It is recommended that you replace the item to prevent incurring more expenditures and causing damage to other components of your water heater.
7. Poor Electrical Wiring
When it comes to electric water heaters, this is generally a concern. The fact that you should always engage a professional to install your water heater is one of the main reasons for this.
If your water heater suddenly stops working, this is the first indication of a defective electrical system. The Solution: Turn off your water heater as soon as possible and contact a professional. Please do not tamper with the electrical wiring system.

Furnace Pilot Light: Where It Is And What Does It Do?
Old furnaces rely heavily on the pilot light to generate heat, which is why it is so crucial to keep the pilot light on. When the gas valve is opened, the flame will continue to burn constantly, igniting the gas. The heat generated by this process then heats the air that is drawn into your furnace, which is then dispersed throughout your house. If your furnace’s pilot light is out, you may notice that it is spewing chilly air into the house. The failure of the pilot light is one of several probable causes of your furnace’s inability to switch on.
You may find the pilot light by following the gas line into your furnace and looking for it there.
From there, you should be able to see a short tube that runs from the gas valve to the burner itself.
Why Furnace Pilot Light keeps going out
There are a variety of reasons why the pilot flame on your furnace continues flickering out of control. Let’s get started!
Faulty Thermocouple Triggers Pilot Light to Go Out
When the pilot flame in your furnace keeps going out, there are a variety of causes for this. Embark on a journey of discovery!
Dirty Thermocouple Makes Pilot Light Keeps Going Out
A filthy thermocouple may cause the safety mechanism to mistakenly trigger, causing the ignition to be turned off. The thermocouple has the potential to accidentally shut off the gas valve and extinguish the blazing flame.
Filthy Pilot Port/Orifice
Examine the flame. If the flame is becoming orange, contact an HVAC professional immediately. If you light your pilot and the flame is yellow, this indicates that your pilot opening is filthy and is preventing your pilot light from keeping lit for long periods of time. A buildup of dirt in the pilot light port might prevent the flame from fully enveloping the thermocouple, which can result in a faulty ignition.
As a result, the safety system is activated, which results in the gas being turned off. This is a fairly typical cause of why your pilot light keeps going out, and it is easy to diagnose.
Bad Gas Regulator
Examine the flames if they are burning. Contact an HVAC professional immediately if the flame is orange! If you light your pilot and the flame is yellow, this indicates that your pilot light is not remaining lit due to a filthy pilot opening. Due to a buildup of dust and grit in the pilot light port, the flame may not be able to completely consume the thermocouple. Consequently, the safety system is activated, which causes the gas to be shut down completely. Your pilot light is most likely being affected by this problem, which is fairly frequent.
Bad Flue Venting Could Blow Out Pilot Light
Excess wind might enter via the openings in your flue pipe if it is loose, broken, or not correctly attached to the furnace. This would extinguish the pilot light flame.
A Strong Draft
There’s always the potential that a powerful draft knocked out your pilot light’s flame and caused it to go out.
How To Re-Light A Furnace Pilot Light?
The first and most crucial step is to locate the owner’s manual for your heater. The handbook will assist you in gaining a better grasp of the internal workings of your individual appliance.
Step 2: Identify Pilot Light
Find the location of the pilot light in your furnace by consulting the owner’s handbook. In order to get access to the furnace, you will need to remove the front of the furnace.
Step 3: Turn OFF Gas
After that, locate the gas valve and shut it down completely. A tiny valve located towards the bottom of the furnace is standard on most models. In general, there are three settings for the gas valve: “ON,” “OFF,” and “PILOT.” Make sure the valve is in the “OFF” position by turning it clockwise. It is critical that you wait for at least 5 minutes after the previous step to ensure that all gas has been expelled from the pipes before proceeding. A disaster might occur if this is not done.
Step 4: WAIT 5 Minutes, then Turn Gas to “Pilot”
Immediately after waiting 5 minutes, switch the gas valve to the “PILOT” position. It is vital that all of the gas has dissipated before switching the gas position to the pilot position. A few of minutes might be the difference between a peaceful society and a disasterous one. Keep in mind that gas is quite explosive!
Step 5: Hold Reset Button
After that, hold down the reset button. However, if you are having difficulty locating the reset button, your furnace’s owner’s handbook should be able to point you in the appropriate place.
Step 6: Press Igniter While Holding Reset Button
Hold the reset button for a few seconds after that. However, if you are having difficulty locating the reset button, your furnace’s owner’s handbook should be able to lead you in the correct way.
Step 7: Turn Gas to “ON” position
Restore the pilot light by turning the gas control valve back to its “ON” position once it has been re-ignited. Right now, you should be able to keep your house warm!
Step 8: If you Aren’t comfortable yet, call a pro!
If, despite doing the necessary measures, you are still unable to keep your pilot light lit, contact an HVAC professional for furnace repair.
Boiler Pilot Light: Where It Is And What Does It Do?
The pilot light in your boiler is vital for the boiler to function properly and generate heat. It is necessary for the pilot to burn constantly in order for it to ignite the gas when the gas valve is opened. When this occurs, your boiler starts heating the water, which is subsequently dispersed throughout your house to provide warmth.
If your pilot light goes out, your boiler and central heating will not be able to operate properly. The pilot light is placed within your boiler, on the other side of the valve from the gas valve. The boiler handbook should help you have a better knowledge of the location of each component.
Why Boiler Pilot Light Goes Out
A malfunctioning, misaligned, filthy, or damaged thermocouple is frequently the source of your pilot light’s failure to illuminate properly. It is the thermocouple that keeps the gas valve from opening if the pilot light is not lit. Your pilot light may not function properly if there is an issue with your thermocouple, or if it is just coated with dirt and debris.
Dirty Pilot Opening
When you turn on your furnace pilot light and find a yellow flame, this indicates that your pilot light is unclean and is causing your furnace pilot light to constantly turning out. If dirt accumulates in the pilot light port, it may prevent the pilot light from completely enveloping the thermocouple with the flame it produces. This causes the thermocouple safety system to be incorrectly activated, resulting in the gas being turned off and the heat being turned off.
Weak Gas Regulator Can Make Pilot Light Keeps Going Out
If you have gas appliances in your home, you will have a gas regulator outside your home. The failure of your gas regulator may result in your furnace not receiving enough gas to keep its pilot light lit. In the event that you observe pilot light issues on more than one device, such as your water heater, it is possible that your gas regulator is broken or weak.
A Strong Draft
A strong airflow has the potential to completely extinguish your pilot light.
How To Re-Light Boiler Pilot Light
Make sure you are familiar with the components of your boiler by reading the instruction manual thoroughly. It is common for the owner’s handbook to contain instructions for re-igniting the pilot light.
Step 2: Shut OFF Boiler
Starting with shutting off the boiler is always a good idea.
Step 3. Shut OFF Gas
Locate the gas valve and turn it to the “OFF” position.
Step 4. Wait 10 Minutes
Continue to check the pipes for around 10 minutes to ensure there is no residual gas.
Step 5. Open Boiler and Locate Pilot Light
After a short period of time, you can turn on the boiler. To obtain access to the pilot light, remove the access panel from the wall. Typically, this panel is positioned next to the gas control knob box, which is where it gets its name. Sometimes you may simply lift the panel up, but other times it may be screwed to the wall or ceiling.
Step 6. Turn Gas to “Pilot”
Now, set the gas control valve to the “Pilot” position on the pilot valve.
Step 7. Hold Reset Button, Then Click Igniter
Next, press and hold the reset button for a few seconds. While still holding down the reset button, press and hold the igniter button until you see a flame appear. It is necessary to press the reset button for an additional 20-30 seconds after the flame is ignited to ensure that it is fully functional.
Step 8. Turn Gas Control Valve To “On” Setting
Press and hold the reset switch for a few seconds to complete the procedure. While holding down the reset button, press and hold the igniter button until you see a flame appear. After the flame has been ignited, you should continue to press the reset button for another 20-30 seconds.
Step 9. Relax in Comfort

Why Does My Pilot Light Keep Going Out?
The most typical reason for your water heater’s pilot light to continuously turning out is a thermocouple that has been broken, bent, or become dusty.
What is a thermocouple?
For the purposes of this definition, it is just a gadget that measures temperature. The component that controls the flow of gas within your water heater or furnace is more significant than you would think. It is made up of two wires. Two people sit in front of a thermostat, while the other sits near the pilot light flame When the temperature rises, the thermocouple generates an electronic signal, which opens the gas valve, allowing the combustion to take place. When the pilot light goes out, the thermocouple detects the reduction in temperature and sends a signal to the gas valve, which closes the valve.
- Over time, dirt, dust, and other types of debris will accumulate on the inside of your water heater.
- This is a simple remedy; simply allow it to cool down before brushing away any dirt or debris.
- The end of the hose that is closest to the pilot light flame is responsible for communicating with the gas valve and telling it whether to open or close.
- Once again, simply wait for your water heater to cool down before bending the pipe backward.
- The thermocouple may be broken or malfunctioning if it is neither bent nor unclean, and if you have troubleshooted both of these concerns.
- If it is not an issue with the thermocouple, it is conceivable that the pilot light aperture is clogged with debris.
A result of doing so is that the pilot flame cools down and so does not adequately heat the thermocouple. If you suspect one of these problems, callComfort Zone HeatingCoolingat 248-414-1302 or submit a service request online, and one of our qualified experts will come out to help you right away.
Water Heater Pilot Light Out In San Francisco, CA? Here’s Why It Happens and What You Should Do!
For the sake of this definition, it is simply defined as a thermometer. The equipment that controls the flow of gas within your water heater or furnace is more significant than the name implies. A total of two wires are attached to the device. One is seated near the thermostat, while the other is seated near the pilot light. A temperature increase causes the thermocouple to transmit an electric signal, which opens a gas valve and enables for combustion to take place. When the pilot light goes out, the thermocouple detects the reduction in temperature and sends a signal to the gas valve, causing it to close.
- Over time, dirt, dust, and other sorts of debris will accumulate on the inside of your water heater’s heating element.
- Remove the dirt or debris with a brush when it has cooled down.
- It’s possible that your thermocouple will flex if this happens.
- If it is bent away from the flame, it will not record any heat and will keep the gas valve closed until the flame is returned.
- If you are unclear of how to continue, do not attempt to repair the problem yourself; instead, contact us and one of our skilled specialists will resolve the problem.
- If you have any questions regarding changing your thermocouple, please call us or submit a service request online now!
- In order to avoid this, the pilot flame must be allowed to cool down before it can properly warm the thermocouple.
Why does a water heater’s pilot light go out?
Here are a few of the most typical reasons why water heater pilot lights go out in the first place:
- A defective thermocouple was discovered. When your pilot light is turned on, your thermocouple is responsible for detecting it. If the thermocouple detects that the pilot light has been extinguished, it automatically cuts off the gas supply to the flame, preventing any potential safety hazards with your water heater. It’s possible that thermocouples will begin to fail over time and will cut off gas supply to the pilot light, even though the pilot light is still burning correctly. A thermocouple that is bent or filthy. Along with regular failure, your thermocouple may suffer from dirt accumulation or the device may become twisted away from the flame of your pilot light, among other things. In either instance, the thermocouple will have a more difficult time sensing your pilot light, and it will shut off the gas supply to the flame
- The flame has been extinguished. If your water heater does not have a sealed combustion chamber, it is possible that the pilot light will be blown out as a result of a powerful draft passing close to your unit. There is insufficient flammable air. There is insufficient flammable air. If your water heater is placed in a utility closet or another area where it is lacking in combustible air, it is possible that the pilot light will not illuminate. A build-up of Carbon Monoxide, which can be fatal, could result as a result of this circumstance.
What should you do when your water heater’s pilot light goes out?
Even if this is the first time this has occurred to you, or if it hasn’t happened in a long time, you can attempt to relight the pilot light on your water heater by following these instructions. For specific information on how to do this with your particular water heater, contact Cabrillo or see the owner’s handbook for your individual equipment. Generally speaking, the procedure will look something like this: 1. Set the thermostat to the lowest possible setting. Switch the on/off/pilot switch to the “pilot” position to begin.
Once the flame has been ignited, press and hold the pilot button for about 60 seconds to verify that the flame remains lighted and is blazing brilliant blue throughout.
6. Turn the knob to the ON position after adjusting the temperature to your liking. We propose that you set it to ‘A’. Install the access panels and reset the thermostat to its default temperature setting. 7.
Contact Cabrillo if your water heater’s pilot light continues to go out
If your pilot light goes out on a regular basis, or if it is not blazing bright blue, call Cabrillo for assistance. The issue is most likely something similar to what we discussed previously (such as a malfunctioning or filthy thermocouple), and it will require the services of a professional plumber to be resolved. To find out what to do if the pilot light on your water heater goes out, or if you’d need a plumbing system serviced or installed in your house, call Jerry Kelly, a plumbing, heating and air conditioning contractor serving the Bay Area and the surrounding areas.

Solved! What to Do When Your Pilot Light Goes Out
Image courtesy of fotosearch.com The temperature in my shower this morning was absolutely freezing, and I mean that in the best way possible. After a brief investigation, I noticed that the pilot light on my water heater had gone out. Is it worth it to try to relight it? A: It all depends on what caused the light to go out. It’s possible that the problem was anything as simple as a draft, a filthy pilot orifice, or a worn-out part—or that the extinguished pilot light was a symptom of something more serious requiring attention.
If you find yourself in this situation, leave your home and call the gas company!
(Please keep in mind that if your water heater has an enclosed burner chamber, you’re most likely out of luck as far as a DIY remedy is concerned; only a professional plumber should be able to reach an enclosed burner chamber.) Make an appointment with a proGet free, no-obligation repair quotes from qualified appliance experts in your area.
When you see your pilot light out, you can usually relight it.
The presence of a downdraft in a vent pipe on a windy day, or even the breeze via an open window, can be sufficient to extinguish a pilot light. It is common for water heaters to include identical relighting instructions, which are usually permanently mounted to the side of the appliance. Image courtesy of fotosearch.com Remove the access cover located at the bottom of the water heater in order to relight the pilot. Ensure that the “Pilot” position is selected for both the control knob and the water temperature knob.
Continue to keep the knob down for a full minute after the pilot is ignited in order to remove any remaining air from the line.
Depending on what happens after the pilot ignites, one of the following options should be considered:
- If the flame continues to burn, you’re good to go!. Simply replace the cover plate, turn the control knob to the “On” position, and set the desired temperature on the water temperature knob to return to the refreshinghotshower experience. Ensure that the pilot light does not flicker and goes out immediately after relighting by cleaning the pilot orifice. Gas flow is impeded by a clogged pilot light aperture, but the solution is straightforward. Shut off the gas to your water heater first, of course (look for a valve on the gas line that supplies the unit). Twist the pilot orifice fitting to the left, which is positioned behind the access cover, to release it from its mounting. After that, remove the orifice itself from the fitting by unscrewing it. Using a cotton swab moistened with rubbing alcohol, thoroughly wipe all surfaces of the fitting once it has been dismantled. As soon as you have completed the reassembling and reattaching of the fitting, relight the pilot light as previously specified. You should replace the thermocouple if you are able to ignite the pilot light but it goes out as soon as you remove the control knob from the pilot light control box. It is a safety device that shuts off gas flow if it detects that the pilot light is out
- However, if it becomes broken, it loses its capacity to regulate the flow of gas. This repair is a little more involved than the previous two, but a replacement is rather inexpensive—often costing less than twenty dollars
Connecting the control panel to the burner assembly, which is hidden behind an access panel, is this item that looks like a copper tube. Turn off the gas to the water heater before beginning any disassembly efforts. Remove the burner assembly from the control panel by detaching the thermocouple tube, the pilot light tube, and the gas supply tube using an adjustable wrench. The burner assembly should simply slide out of the way. (Tip: Because thermocouples come in a variety of sizes and kinds, bringing the broken thermocouple with you when purchasing a replacement is the most effective approach to ensure that you receive an identical match.) Replacing the broken thermocouple with a new one is followed by reassembling the burner assembly, reattaching the tubes, and relighting the pilot light in the manner indicated above.
Water Heater Pilot Light: What causes it to go out?
For households who have gas-powered water heaters, a broken or defective pilot light may be a huge source of aggravation and trouble. There is nothing more aggravating than turning on the water faucet only to discover that there is no hot water available. This is especially true when it comes to getting ready for bed. A variety of factors might cause your pilot light to fail or to go out completely. The thermocouple is directly responsible for the vast majority of pilot light problems. What is a Thermocouple and how does it work?
- A thermocouple in a water heater is a safety device that is meant to prevent the discharge of flammable gas, which may ignite and produce a potentially hazardous explosion.
- One end attaches to the thermostat, while the other extends into the main burner, with its sensory tip positioned within the pilot light flame, and is attached to the thermostat.
- If the pilot flame does not provide enough heat, or if it burns out, the thermocouple cools down, the electric signal is interrupted, and the gas valve is shut down.
- Because the thermocouple’s tip comes in close contact with a flame, carbon can accumulate and cause the flame to malfunction or go out.
- Thermocouple with a bent tip A twisted thermocouple or one that is not in direct contact with the flame will indicate that the pilot light is not working or is malfunctioning.
- Pilot light tube that has become dirty The pilot light tube is responsible for delivering gas to the flame.
- When this occurs, the small apertures at the end of the tube become clogged, causing the pilot flame to change or go out completely.
- Thermocouple that has been damaged Because of the harsh circumstances to which thermocouples are subjected, as well as the delicate nature of their design, thermocouples do occasionally burn out or fail.
- The following cleaning and maintenance techniques for a gas-powered water heater may appear simple, but it is strongly suggested that you employ a qualified and certified plumbing contractor to service your system.

How to Fix a Water Heater Pilot Light
Time Approximately one hour or less Complexity Cost for a beginner is less than $20.
If your hot water heater suddenly stops operating, it’s likely that a faulty thermocouple has caused the gas to the pilot light to be turned off. Replacement is a simple do-it-yourself project.
Is there no hot water? If you have a natural gas or propane water heater, there is a good probability that the pilot light has gone out. It is this little flame that starts the gas burner on your water heater that is referred to as the pilot light. When the pilot light on your water heater goes out, the first thing you should do is try to relight it by following the instructions on the water heater label. The thermocouple is by far the most prevalent cause of pilot failure, whether it occurs immediately after lighting or on a regular basis after the pilot has been extinguished.
If you do not wait for a professional to arrive, you will be able to get your hot water running without incurring the expense of a service visit.
What is a Thermocouple?
- In order for gas to flow to the burner, a thermocouple must be used to detect the heat of the pilot. A faulty thermocouple will prevent gas from reaching both the pilot and the burner, resulting in the pilot light failing to stay lit.
Project step-by-step (6)
- In order for gas to flow to the burner, a thermocouple must be used to detect the heat from the pilot. Due to a malfunctioning thermocouple, the pilot and burner will be deprived of gas, resulting in the pilot light failing to illuminate.
Unscrew the Nuts
- Turn off the control valve if it is on. Remove the burner access covers and loosen the bolts on the gas, pilot, and thermocouple lines to free up the burner.

Remove the Assembly
- Remove the water heater pilot light burner component from the water heater. Remove the old thermocouple by unscrewing or pulling it out. Purchase a new one that is the same size and length as the previous one
Install the New Thermocouple
- Install the new thermocouple in the same manner as the previous one
- Replace the burner assembly by sliding it back in. Reattach the three wires to the control valve where they were disconnected.
Reattach the Lines to the Gas Valve
- The three lines must be reconnected to the gas valve by threading the nuts into position with your fingers and hand-tightening them
- A quarter- to half-turn of the wrench tightens them up.
- Pro tip: Because the metals are delicate, avoid overtightening them.
Test for Gas Leaks
- Keep in mind that in order to test for leaks, the pilot light must be lighted and the burner turned on so that gas flows through the big tube.
- Replenish the water supply by opening the shutdown valve and lighting the pilot light. Turn the control valve to the “on” position. Use a 50/50 mixture of dish soap and water to check the screw joints for air bubbles, which indicate a leak, while the gas burner is turned on.
- Keep in mind that when the water heater pilot light is re-ignited, the flame should wrap around the thermocouple bulb.
During this procedure, you should not be able to detect the scent of gas (except for a slight whiff when you remove the gas lines). If you find yourself in this situation, exit the house immediately and contact your gas provider.
WhenNotto Replace the Thermocouple
Some gas water heaters have a burner chamber that is “closed,” making it impossible to reach the burner. It is recommended that you contact a professional to repair this sort of heater. In addition, some gas water heaters are not equipped with pilot lights. Allow the professionals to take care of this as well.
5 Reasons Why Your Water Heater Pilot Light Won’t Stay Lit (and How to Fix)
Please keep in mind that this content may contain affiliate links. This means that, at no additional cost to you, we may gain a small profit on purchases made via our links. Below is a list of the top five reasons your pilot won’t stay on the flight, as well as solutions for each problem. Important Important: Before performing any of these diagnostics or repairs, switch off the gas and wait at least five minutes for the gas pressure and fumes to dissipate before starting the engine. Generally speaking, this is a decent rule of thumb for relighting the pilot in general, and not simply for diagnostic purposes.
Reason 1: Dirty Pilot Tube
Dirt and debris can accumulate in the pilot tube, preventing the flow of gas from flowing properly. As a result, the pilot does not receive enough fuel to keep the engine running. If the pilot will not ignite at all, this is also a plausible explanation. Fortunately, a clogged pilot tube is the most straightforward problem to resolve.
How to Fix
All that is required is a needle to be inserted into the pilot hole and carefully removed from the hole. If there is a significant amount of material in the tube, it may take many attempts to finish the procedure.
Checking to determine if this step was successful is as simple as igniting the pilot and observing whether or not it lights up properly and remains lighted. A flame that is in good health will be blue in hue.
Reason 2: Kink in the Flex Tube
The fuel is sent to the flex tube by the gas controller. On rare occasions, the tube might get kinked, preventing the flow of gas from continuing. This is one of the most typical reasons why the burner won’t stay lit, even though the pilot appears to be in proper operating condition. Although it is not as prevalent as thermocouple problems, it is a simple remedy and should be ruled out as soon as possible.
How to Fix
Perhaps the simplest problem to resolve, you only need to search for any kinks in the tube and unkink them, as seen in the picture. If the problem persists, it is possible that you are experiencing a problem with the thermocouple.
Reason 3: Obstruction in the Thermocouple
Thermocouple issues are very prevalent, and this component is frequently the source of the problem when the water heater’s pilot light keeps blinking. This gadget is meant to detect the presence or absence of a pilot light by picking up an electrical signal from the heat generated by the pilot light. When dirt particles get in the way of this signal, it might cause it to be distorted, leading the thermocouple to assume that the pilot has gone out of range. It then takes the precautionary step of shutting down the gas supply.
How to Fix
Check to see that the thermocouple is completely cool to the touch. Afterwards, use a piece of fine grit sandpaper and gently rub the surface to remove any dust that has accumulated over time. This should confirm that the component is correctly functioning. Although unlikely, if this procedure fails to resolve the issue, thermocouple replacement may be required owing to component failure.
Reason 4: Damaged Thermocouple
Check to verify that the thermocouple is completely cold to the touch before continuing. After that, you will need to carefully sand the surface with a piece of fine grit sandpaper to remove any remaining filth. Making ensuring the component is functioning properly should be a priority at this point. However, if this procedure fails to resolve the issue, it may be essential to replace the thermocouple due to component failure.
How to Fix
Take a look at the thermocouple. When the pilot is ignited, the sensor at the end of the hose should faintly contact the flame. It may become bent away from the flame; if this happens, gently bend it back. Using a multimeter, check that the thermocouple is in good working order and does not exhibit any symptoms of damage. The value should be more than 20MV. Any reading that is lower than this is a strong indication that the thermocouple itself has been damaged and must be replaced immediately.
Reason 5: Main Control Valve
The thermocouple should be inspected. During the pilot’s ignition, the sensor at the end should make a gentle contact with it. If it has been twisted away from the flame, gently bend it back toward it. b. Using a multimeter, check that the thermocouple is in good working order and does not exhibit symptoms of wear. There should be more than 20MV in the reading. Anyone who receives a reading that falls below this threshold has a thermocouple that has to be changed.
How to Fix
Control valves that have failed can only be repaired or replaced if they are completely destroyed.
This can be more expensive than other do-it-yourself difficulties, and it can be more challenging for individuals who are not familiar with this type of job.
When All Else Fails
Almost every one of the problems listed above may be identified and corrected by the typical homeowner. However, there may be rare instances in which the pilot refuses to stay on even after you’ve exhausted all of the above-mentioned possibilities. In such extreme circumstances, the only option is to bring in a professional to thoroughly inspect the water heater. However, even in the worst-case situation, the entire heater may need to be replaced; however, the problem is most typically one that can be resolved with the correct equipment and materials.
8 Reasons Why Your Water Heater Pilot Light Won’t Stay Lit
Even the most novice homeowner can detect and correct all of the issues listed above. a) Even after you’ve tried all of your options, there may be instances in which the pilot refuses to stay on the flightplane. It is only in such extreme instances that it is possible to bring in a professional to thoroughly inspect the water heater. However, even in the worst-case situation, the entire heater may need to be replaced; however, most problems can be resolved with the correct equipment and components.
Why Does Your Heater’s Pilot Light Keep Going Off?
The following are the most typical reasons why the pilot light on your heater won’t remain lit:
1. Obstructed Thermocouple
The thermocouple is used in the operation of the majority of newly developed water heaters. This component is the primary cause for the operation of your water heater; it also determines whether the pilot light is on or off by drawing electricity from the heat generated by the pilot. When the thermocouple senses that the pilot light is not lit, it automatically shuts off the gas as a safety precaution. It is also possible that an unlit pilot is caused by a dirty thermocouple, since the dirt may be obscuring the current signal, which would result in a gas leak.
You don’t want to take the chance of causing a leak when cleaning your thermocouple.
2. Bent Thermocouple
The thermocouple can get curved or bent to the point that it begins to lose the heat signal generated by the electrical current, in addition to being dusty and grimy and becoming bent. The thermocouple may have bent too far away from the pilot in the majority of cases, which is problematic since it will not be able to detect the heat signal. Make sure your thermocouple is straight: Normally, the flame is meant to come into contact with the thermocouple just enough for it to detect heat. It is possible to correct a bent thermocouple by bending it back towards the pilot, if you discover that it is bent.
3. Damaged Thermocouple
The thermocouple can get curved or bent to the point where it begins to lose the heat signal generated by the electrical current, in addition to being dusty and grimy and being bent. It is common for thermocouples to be bent too far away from the pilot, which is troublesome since the thermocouple won’t be able to detect any heat signals. Make sure your thermocouple is in the proper orientation: It is normal for the flame to make a tiny contact with the thermocouple in order for it to detect the heat produced.
It is possible to correct a bent thermocouple by bending it back towards the pilot, if you discover that it is bent. Don’t forget to wait for it to cool down before you start working with it.
4. Dirty Pilot Tube
A filthy pilot tube may be a contributing factor to the malfunctioning of your water heater if you have already tested the thermocouple and found it to be in good working order, as previously stated. If you’re wondering why your tankless gas water heater isn’t working, it’s because your pilot tube may be clogged or completely covered by dirt, which prevents the gas from flowing as it should. Remove the pilot tube and clean it: If this is the case, your pilot tube will require extensive cleaning in order to perform correctly.
Keep an eye out for huge objects, since they may be the most common cause of accidents.
If it doesn’t, take the tube out and clean it well again.
5. Flex Tube Defects
This is another another possible explanation for why your pilot’s light is not working. The flex tube is responsible for delivering gas to the device, and if the continuous flow of gas is disrupted, the pilot light will fail to illuminate. When the tube is kinked at one or more spots, this is the most common occurrence. Check the flex tube for damage: Check the tube along its length to ensure that it is straight and there is no restriction to the passage of gas. However, if this does not resolve the issue, you may be forced to replace the tube totally, which would be costly.
6. Main Control Valve
This is also another probable explanation for why your pilot’s light isn’t turning on anymore. The flex tube is responsible for delivering gas to the device, and if the constant flow of gas is disrupted, the pilot light will not remain on. When the tube is kinked at one or more locations, this is the most common symptom. The flexible tubing should be checked. Check the tube throughout its length to ensure that it is straight and there is no block to gas passage. It’s possible that if this doesn’t work, you’ll have to replace the tube altogether.
Flex tube issues are less common than other types of tube failure.
7. Faulty Electrical System
The majority of the blame for this problem may be assigned to electric water heaters. This problem is frequently caused by incorrect wiring of the internal electronics. A badly connected electrical water heater has a tendency to blow the fuse and short circuit the circuits, which are the two most common problems that an electric water heater encounters. It is common for a malfunctioning electrical system to be identified by a breaker shutdown, which results in the water heater being shut off without the user’s knowledge.
What to do to repair it: If you have reason to believe that there is a problem with the electrical wiring, you should get it checked by a professional. If you do not have sufficient experience, do not attempt to repair it yourself.
8. A faulty burner
If your water heater’s burner is malfunctioning, it is possible that this may have an impact on ignition, which may result in the pilot light going out. What to do to repair it: In the vast majority of situations, it is preferable to replace the burner totally; however, you may do some basic inspections first. Turn on your hot water faucet and wait for the burner to come to life, which should take 4 to 5 minutes. To test if the burner ignites after trying this, try moving to a lower temperature and then back to the original setting.
How to Re-Ignite the Pilot Light
Every water heater comes with a set of installation instructions. Because you will be working with gas, you should act with utmost caution before proceeding with this step. Set your thermostat on the heat setting and raise the temperature to around 80 degrees to keep it running. Look for the pilot valve on your furnace and attempt to locate the on/off switch. Once you find the switch, turn it to the “off” position. The pilot light should be located near to the gas burner tube; pay particular attention to it.
Once the pilot is activated, return the knob to the “on” position.
Using this method, you can ensure that the thermocouple heats up sufficiently to notify the pilot light to illuminate.
If you repeat the process five times and the result remains the same, it is possible that there are additional issues at play.
Take advantage of your warranty
The installation of a water heater is covered under the manufacturer’s warranty. Because you will be working with gas, you should proceed with utmost caution before moving further with this step. Keep it running by setting your thermostat to heat mode and raising it to around 80 degrees. To turn off your furnace, locate the pilot valve and the on/off switch, and then turn the switch to the “off” position. It is important to keep the pilot light near to the gas burner tube and to pay close attention to it.
The knob should be turned back to “on” once the pilot has been activated.
This is done to ensure that the thermocouple heats up sufficiently to notify the pilot light to illuminate.
It’s possible that additional issues are at play if you perform the process five times and get the same outcome each time.
Hire a technician
Depending on whether your water heater has outlived its warranty time and if you’ve carried out all of the recommended maintenance and adjustments, this may be your only option. While most homeowners would consider this a last choice, it is important to remember that the majority of individuals are not DIY enthusiasts. Additionally, dealing with gas and electricity is quite delicate, which is why you should exercise extreme caution. Hiring a professional may result in more charges, but it may also result in you being safer, which should be your number one priority.
To be sure, employing a professional or a handyman will prevent you from damaging anything else, which will result in a more expensive repair bill later on. A technician also has the ability to predict potential problems in the future and to provide advise or solutions to help avoid them.
It is possible for a variety of things to go wrong and for your pilot light to fail to stay illuminated. The thermocouple, pilot tube, flex tube, and main control valve, on the other hand, are the traditional suspects in this case. The advice in this blog should assist you in resolving these challenges, or at the very least in determining the root cause of the problem. If nothing seems to work, you should seek the services of a qualified specialist to repair the pilot light. Have you ever had to deal with a pilot who was unable to light his or her engine?
