8 Reasons Why Your Water Heater Pilot Light Won’t Stay Lit
- For those of you who aren’t technicians, I can imagine that there’s nothing more frustrating than trying to keep a pilot light lit when it won’t remain lit for whatever reason at that moment.
- Along with interfering with the proper operation of the furnace, it can also hinder you from enjoying the luxury of a hot morning shower.
- There are a variety of reasons why your pilot light keeps flickering on and off repeatedly.
- We’ll do our best to cover all of the probable explanations for your heater’s current state of malfunction.
Continue reading to the conclusion of the blog so that you may be informed of the causes for the errors and learn how to avoid them in the future.Following a discussion of the underlying reasons, we will offer some suggestions for potential remedies that you may utilize to resolve the issue.
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 produced 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.
Maintain the cleanliness of your thermocouple: While it is possible to clean your thermocouple, you must first ensure that the gas valve is turned off, as you do not want to risk causing it to leak while cleaning.The thermocouple may be found and cleaned with relative ease.
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.
Don’t forget to wait for it to cool down before you start working on it.
3. Damaged Thermocouple
- Another cause for your pilot not to be lit might be due to a faulty thermocouple in the ignition system.
- If you inspect the thermocouple and find it to be clean, filthy, or curved, it is possible that it has been damaged.
- Removing the thermocouple and testing it with a multimeter will help to confirm your assumptions.
- Before removing the thermocouple, make sure that the gas is switched off and that the thermocouple is completely cold before doing so.
If the voltage it produces is less than 20 MV, it is considered damaged.Solutions for a Damaged Thermocouple: A damaged thermocouple is rather technical, and as such, you may require the assistance of an experienced technician if you do not have such training.When a thermocouple is just slightly damaged, it is possible to repair it.If the damage is severe enough, you may be forced to replace 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.
- You might be asking how this prevents your tankless gas water heater from functioning properly.
- Your pilot tube may be clogged or completely blocked by dirt, and the gas will be unable to flow as it should as a result.
- Remove the pilot tube and clean it: If this is the case, your pilot tube will require extensive cleaning in order to perform correctly.
Once all of the appropriate measures have been taken, a tiny needle should be used to clean the pilot tube.Keep an eye out for huge objects, since they may be the most common cause of accidents.When you’re finished, turn on the heater and check to see whether the pilot light remains lit.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.Before you resort to changing the tubes, be certain that you’ve checked all of the other possibilities first, because flex tube problems are less common in general.
6. Main Control Valve
- A defective main control might be the source of the pilot light’s inability to remain lit.
- This is still another issue that happens less frequently, so you must rule out all other possibilities before concluding that the error is due to the primary control system.
- If you’re not sure about something, check the controls with your multimeter.
- To replace the control valve, follow these steps: Control valves are frequently repaired by technicians, even if the valve itself is not malfunctioning.
However, if you want your water heater to run as long as possible and if you want to save future costs, you might think about replacing the main control valve altogether instead.
7. Faulty Electrical System
- Most of the blame for this problem may be placed on 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.
If it doesn’t, it’s time to get another one.
How to Re-Ignite the Pilot Light
- Every water heater is included with a set of instructions for use.
- 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.Initiate the flame with a long match while simultaneously switching the knob to ″pilot″ and holding it in that position for 35 seconds.Once the pilot is activated, return the knob to the ″on″ position.If the preceding approach fails to produce results, repeat the operation while increasing the waiting period to 60 seconds.
Using this method, you can ensure that the thermocouple heats up sufficiently to notify the pilot light to illuminate.This is referred to as ″jump-starting″ the thermocouple in some circles.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
Most water heaters are covered by a 1- or 2-year guarantee in the majority of instances. If your pilot light malfunctions during this time period, you may always return to the store where you purchased it and get it repaired there. This is quite advantageous since, in the majority of situations, they will be able to fix any broken equipment or even completely replace the water heater.
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.

- This is something that can happen as you become older.
- More information on the life expectancy of water heaters can be found in this page titled How long do water heaters last?
Let’s have a look at how to identify whether a thermocouple is faulty in the section below.
How to Determine If You Have Gas Hot Water Heater Thermocouple Issues
- At the heart of your water heater is a thermocouple, which detects heat emanating from the pilot light and regulates the flow of gas to the burner.
- When a thermocouple fails, gas will be cut off to both the pilot and the burner, which is when people realize that the water heater pilot light has gone out in the first place.
- The pilot light on your water heater works in conjunction with the rest of the unit.
- When your thermocouple senses that the pilot light on your water heater is not lit, it immediately turns off the gas to your water heater as a safety measure.
The likelihood of your item being damaged increases if you establish that your thermocouple is actually broken — that is, there are no indicators of being bent or unclean.You will need to replace the equipment or have it professionally fixed in order to resolve this problem.This is an excellent opportunity to clear up any misunderstandings.
How to Replace Thermocouple on Water Heater?
- Water heater repairs are something that HVAC firms are occasionally called upon to do.
- While some people are capable of doing this procedure, it is recommended that you get a certified plumber to assist you.
- If you’re in the area, we’re a plumber in Arlington TX who can change the thermocouple in your hot water heater on a regular basis for you.
- However, there is some good news.
Most thermocouples may be replaced at a low cost and in a short period of time, sometimes in less than an hour, by a capable homeowner with some basic tools.
Determining the Thermocouple Issue If It’s Not Broken
- Your thermocouple, on the other hand, may not necessarily be faulty.
- If it’s contaminated, the electric current from the pilot may be disturbed, resulting in a gas leak from the pilot.
- This is a simple problem to solve.
- The following are the steps to cleaning your thermocouple: Locate the thermocouple and clean it with a piece of sandpaper once it has been cleaned.
Always remember to turn off the gas before you begin cleaning, and to make sure that your thermocouple is completely cold before you begin cleaning.If your attempt at water heater thermocouple cleaning fails to resolve the problem, it is possible that the thermocouple is bent.When it is bent to a certain degree away from the pilot light, it ceases to work since it will no longer be able to detect heat.This is likewise a straightforward fix: simply bend the thermocouple back into its original position.As a last step, bend the thermocouple back until it is close enough to the pilot flame that the thermocouple is faintly touched by the flame.
If this is the case, the problem is usually simply resolved by following the procedures outlined above.
When Not to Replace Your Thermocouple
In the case of a gas water heater with a closed burner chamber or one that does not have a pilot light, entry will be far more difficult. In order to replace this sort of thermocouple, you will almost certainly require the assistance of a specialist.

7 Reasons Why Water Heater Pilot Light Won’t Stay Lit
- Water heaters are one of the most important items in every household.
- However, when the water heater pilot light won’t remain lit, it may be quite aggravating.
- If you are not a plumber or expert, we can imagine that dealing with a water heater pilot light that keeps going out, rather than a thermocouple, is the most frustrating issue you are dealing with right now.
- Aside from impairing the proper operation of the furnace, it can also prevent you from receiving steaming hot water for your first shower of the day in the morning.
There are a variety of reasons why the pilot light fails on a regular basis.We will make every effort to inform you of all of the possible reasons why your unit is in such poor condition, as well as simple treatments that you may be able to do on your own.We always recommend that you use a professional service for complicated or potentially dangerous repairs, such as a plumber or a gas company.In this case, we will inform you of the difficulties that should only be handled by professionals.
7 Reasons Why Water Heater Pilot Light Won’t Stay Lit
- If your natural gas water heating equipment goes off often, it is possible that you have a defective thermocouple in your system.
- Most gas-powered types use a standing pilot to ignite the burner, which is common in the industry.
- In order for the pilot assembly to function properly, both the main gas valve and the thermocouple must be operational.
- The thermocouple is a heat-detecting probe that is used to measure temperature.
It is an important component of the pilot assembly, and it is attached just above the pilot flame when assembled.It is possible that the thermocouple will generate a small current that will be sent back to the gas valve, which will keep the gas flowing to the pilot light if everything is operating properly.However, if the thermocouple is broken, it will not be able to recognize the flame, and the gas valve will not be able to receive the necessary power signal to maintain the gas flowing to the pilot assembly.It will eventually trip off the pilot flame since it will remain consistently in the pilot flame.To test the thermocouple, you’ll need to use specialized testing equipment.
The most effective method of troubleshooting is to replace the component.Before censuring the thermocouple, make sure that the pilot flame is clean and thoroughly connects with the probe’s end on the other end.You will not have to deal with any gas fittings while you are changing it.Local protocols, on the other hand, may dictate that a specialist plumber be called in to remedy the problem.
- Another key factor to consider when the pilot light on a water heater keeps going out is the burner.
- It heats the water by burning the entering gas, which produces steaming warm water.
- A faulty pilot light will result in improper operation of the pilot light.
- We do not recommend that you attempt to repair or replace the burner on your own, but you can test it to determine if this is a potential problem.
To begin, turn on the warm water faucet and let it run for a few minutes.Proceed to the unit and pay close attention for the sound of the burner turning on.It is typically accompanied by a whump or whoosh sound.Unless you hear any sound, it is a definite indication that your burner is faulty.Obtain the services of a professional to thoroughly check it and replace any malfunctioning components.
Dirty Pilot Tube
- If your water heater’s pilot would not light, it is possible that the pilot tube is clogged with debris.
- If you’re wondering how dirt might interfere with your device’s operation, consider that your pilot tube may be partially or completely clogged by dirt, preventing the gas from traveling as it should.
- In such a circumstance, it is necessary to thoroughly clean the area in order for it to function properly.
- As soon as you have taken the required safety steps, clean the tube with a little needle.
Keep an eye out for huge items, since they may be the most significant reason of a water heater failing to stay lighted.As soon as you’re finished, check the tankless water heater to verify if the pilot light continues to glow.If the water heater pilot fails to ignite, remove the tubing and thoroughly clean it.
Flex Tube Problems
- It’s also possible that a flex tubing is causing the water heater pilot to continuously going out.
- This tube connects directly to the gas controller, ensuring a consistent flow of gas.
- Nonetheless, the pipe turns around from time to time, preventing the required system function from being performed.
- To get rid of the problem in this situation, untangle the tube.
If this does not resolve the issue, the tube should be replaced.When compared to thermocouple difficulties, flex tubing concerns are quite infrequent.
Main Thermostatic Control Or Gas Valve
- The thermostatic control or gas valve may also be the source of the pilot light going off on a consistent basis.
- It is referred to as the primary control valve in some circles.
- Even though this problem only occurs seldom, it is a probable reason of a water heater pilot light failing to stay lit.
- Professional knowledge and skills are also required to solve this challenge.
They will use a multimeter to properly check the part to determine whether or not it is defective.If the answer is true, they will either repair or replace the defective element.
Lack Of Combustible Air
- Another reason why the pilot light on a water heater won’t remain lit is a lack of combustible air flow.
- Your device need air to maintain the pilot light burning; otherwise, it will shut off the electricity supply.
- Check to be that your gadget is not surrounded by dirt, debris, or other contaminants that might increase the quantity of flammable air available to it.
- You should keep the area around your heater as clean as possible.
Electrical System Defect
- In addition, sloppy wiring might make it impossible for the pilot light to stay lit.
- When comparing electric water heaters to gas water heaters, this is a problem that arises more frequently.
- Your equipment may face a variety of electrical problems if the wiring is incorrect.
- This means that you will not be able to acquire hot water in such circumstances.
If your appliance develops an electrical fault, the breaker shutdown will immediately shut down the main breaker to protect the appliance.As a result, consult with a specialist or a plumber to have the electrical wiring checked.
What Should You Do If The Hot Water Heater Pilot Light Keeps Going Out?
- All water heaters are shipped with a set of installation instructions.
- You should take safety precautions before attempting to repair your gadget because you will be working with gas and electricity.
- Set the thermostat to the heat setting of 80 degrees and leave it there.
- Locate the pilot valve on the furnace and the on/off handle, and turn the on/off handle to the ″off″ position.
Locate the pilot light, which should be near the gas burner tube at this point.Turn on the flame and turn the handle to the pilot position, holding it there for 35 seconds.Once the pilot has ignited, turn the handle to the ″on″ position.If this approach does not work, repeat the procedure, but this time wait for 60 seconds instead of 35 seconds the first time you tried it.As a result, the thermocouple heats up to the point where it signals the pilot light to turn on.
If you try this procedure five times and the water heater pilot light does not stay lit, it is possible that there is a problem with the water heater itself.
Claim The Warranty
Many water heaters come with a guarantee of one or two years. If the pilot light on your water heater does not come on during this time, you should contact the manufacturer to have the problem rectified. This is quite advantageous since they will repair any malfunctioning parts, as well as the heater in its whole.

5 Reasons Why Your Gas Water Heater Pilot Light Won’t Stay Lit
- Consider the following scenario: you wake up in the morning and your water has failed to heat.
- What are you going to do?
- You have no choice but to face the elements and embrace the bone-chilling cold if you don’t want to start the day without a bath or shower.
- When the pilot light on your gas water heater won’t remain lit, this is precisely what you may expect to see happen.
In spite of your best efforts, you may still have the pilot light turning out.a) So, what really is the situation?Here are five reasons why your pilot light won’t remain lit, as well as solutions to the problem.If you want assistance with your water heater and are unsure of the nature of the problem, please let us know what you require and one of our specialists will be in touch.
- The thermocouple has been distorted. Located at the bottom of the water heater in the pilot assembly is a thermocouple that regulates the temperature of the water heater. Made of a tiny rod and copper wire, it acts as a safety device, allowing the gas to be turned off in the event of an emergency. When the pilot light is operating properly, it will strike the thermocouple rod, which will create a little electrical current that will keep the gas valve open. It is possible that the thermocouple will be twisted too far away from the pilot, resulting in the failure of the complete water heater. If you take the right safety precautions and turn off your gas, you may be able to bend the thermocouple back into its normal position again.
- The thermocouple is contaminated beyond repair. If the thermocouple is filthy, you may notice a reduction in the amount of electrical current that is produced. Dirt and grime are not ordinary to encounter, and cleaning them should not be too time-consuming or complicated. Once again, take safety measures by shutting off your gas and making sure the thermocouple is cool to the touch before proceeding. Use a piece of sandpaper to remove any dirt or grime from the surface for the best results.
- Damage to the thermocouple has occurred. There is a possibility that your thermocouple has simply failed and is the cause of your pilot light failing to illuminate. If you’re reasonably convinced that the thermocouple is the source of the problem, you’ll need to get it replaced or fixed as soon as possible. Fortunately for you, the parts required for the replacement/repair should be less than $20, and the time required to do the repair will be minimal. You will be able to save money on labor costs as a result of this. Make use of a multimeter to check the voltage going through the thermocouple to verify it is not damaged. Any thermocouple voltage value less than 20 MV indicates a faulty thermocouple.
- The pilot tube is clogged with dirt. A typical occurrence is the accumulation of dirt and debris in the pilot tube. If an excessive amount of gas accumulates, the flow of gas may get obstructed. Fortunately, cleaning out the pilot tube is not difficult, and you may complete it without the aid of a professional. In order to begin the operation, switch off the gas and allow the tube to cool for several minutes. Once the gas has cooled, use a needle to remove away anything that could be obstructing the passage of gas. After everything has been thoroughly cleaned out, re-ignite the gas and check to see whether the pilot lights up. It goes without saying that if it does not, your problem is most likely not caused by the pilot tube.
- A problem has been identified with the flex tube. The flex tube is responsible for connecting the gas controller to the rest of the system. A problem with the flex tube is less prevalent, but it might cause a reduction in the amount of gas that can be used by the system. Check to see if there are any kinks in the tube, and if there are, undo the kinks to see if it helps to resolve the issue. A new piece of tubing will very certainly be required if eliminating the kink does not alleviate the situation.

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.
- Lighting the pilot and watching to see whether it lights properly and remains lighted is all that is required to determine whether or not this step was successful.
- 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. However, if this procedure is unsuccessful in resolving the issue, thermocouple replacement may be required owing to component failure.
Reason 4: Damaged Thermocouple
This is a more serious issue, since it may necessitate the replacement of the component. Damage may manifest itself in the form of the sensor being bent too far away from the pilot light, or it may indicate that the entire unit is no longer operable.
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
- This is the problem that you want to avoid at all costs among the ones that you can diagnose on your own.
- The quickest and most straightforward method of diagnosing a faulty control valve is to exhaust all other possibilities first.
- Given that all other possibilities have been checked out and that the thermocouple is displaying data on the multimeter, this is probably definitely the cause of the problem.
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.
- The worst-case situation may need the replacement of the entire heater, but the problem is most typically one that can be resolved with the use of the correct tools and replacement components.
Why Does My Pilot Light Keep Going Out?
The most typical reason that your water heater’s pilot light continues going out is that the thermocouple has been broken, distorted, or become clogged with debris.
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.If you have a defective thermocouple, this is the most likely cause for your pilot light to be inoperable.Over time, dirt, dust, and other types of debris will accumulate on the inside of your water heater.The accumulation of material on your thermocouple might cause it to malfunction.This is a simple remedy; simply allow it to cool down before brushing away any dirt or debris.
It’s possible that your thermocouple will flex.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.The gas valve will remain closed if the thermocouple is twisted away from the flame and does not record heat.Once again, simply wait for your water heater to cool down before bending the pipe backward.
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.The thermocouple may be broken or malfunctioning if it is neither bent nor unclean, and if you have troubleshooted both of these concerns.To find out if your thermocouple needs to be replaced, call us now or submit a service request online.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.

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
It is meant to shut off the gas valve if the pilot light goes out, and it is used in conjunction with a thermocouple. Thermocouples can be damaged or worn out over time. If the thermocouple is incorrectly positioned or malfunctioning, the gas valve may be incorrectly shut off, as well as preventing the pilot light from keeping lit.
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
- If you have gas appliances in your house, you will also have a gas regulator outside of your home to regulate the flow of gas into your home.
- Your furnace may not receive enough gas to keep its pilot light lit if your gas regulator isn’t functioning correctly.
- There is a good chance that you have a defective gas regulator if the pilot light is out in more than one home appliance, such as your water heater.
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?

Diagnosing and fixing a thermocouple “no hot water” problem
- Your gas water heater’s burner chamber has what’s known as a thermocouple, which is a little metal cylinder that sits directly in front of the pilot light.
- The thermocouple is a safety device that detects when the pilot light is on and has to be replaced.
- If the pilot light goes out, the thermocouple sends a signal to the gas valve, which keeps the valve closed until the pilot light returns.
A worn out thermocouple is one of the most common gas water heater problems
- Thermalcouples wear down over time, causing the pilot light to go out, the burner to not fire, and the lack of hot water to result.
- First, try re-igniting the pilot by following the instructions on the tank’s side panel.
- It is possible that the thermocouple is defective if the pilot ignites but the flame goes out as soon as you release the button after holding it for 60 seconds.
- It is feasible to change the thermocouple without having to disassemble the burner assembly, and many repair technicians do so.It is feasible to change the thermocouple without having to disassemble the burner assembly, and many repair technicians do so.
