How to Clean the Thermocouple on a Water Heater — FAQs

How do I know if my thermocouple is bad?

It is common to find a pilot light in the vicinity of a thermocouple.The thermocouple’s principal function is to maintain the pilot light’s illumination for as long as the device for which it is designed is in operation.Consequently, if the pilot light fails to illuminate, it’s possible that the thermocouple is at fault.In the case of a gas water heater, if the light does not come on at all and you are certain that the gas is turned on, a blockage in the pilot tube may be the source of the problem.When you let off of the gas knob, however, the flame will ignite and then go out, indicating that the thermocouple is at fault.

What are some types of thermocouple?

• Thermal couplings are available in a variety of shapes and sizes, each of which is best suited for a certain purpose. They differ in terms of characteristics, stability, melting points, and so on. The following are examples of thermocouples in various configurations: Types B, R, and S of platinum/rhodium alloy thermocouples
• Types C, D, and G of tungsten/rhenium alloy thermocouples
• Types E, J, K, M, N, and T of nickel-alloy thermocouples
• Types P, Iridium/Rhodium alloy, HTIR-TC, Pure noble-metal, and Platinum/Molybdenum alloy thermocouples
• Types E, J, K,

Are there universal thermocouple?

Some thermocouples are constructed with adapter fittings that allow them to be used with many types of pilots, including scree-in, push-in, and clamp type pilots.These thermocouples are frequently used in 30 mV systems and in gas furnaces, among other applications.Please do not assume that because thermocouples are universally applicable, they may be used for any purpose.There are several different varieties of thermocouples, each of which is ideally suited for the application for which it was designed.

What is the difference between a thermocouple and an RTD?

Thermocouples and RTDs (Resistance Temperature Detectors) are both used to measure temperature changes, with the difference being that RTDs do so using the concept of resistance to the passage of electricity rather than resistance to heat.When comparing thermocouples to resistance thermometers, one major distinction is that thermocouples are more sensitive and respond faster.The other distinction between RTDs and thermocouples is that RTDs are more exact.While an RTD can be accurate to within 0.1 degrees Celsius, a thermocouple is not accurate to within 1 degree Celsius at any temperature.

What can make a thermocouple fail?

A thermocouple is a device that responds to temperature changes by expanding and contracting in response.This will cause the thermocouple to degrade over time if it occurs too frequently.If the rapid temperature changes persist, the thermocouple will eventually fail and will be unable to perform its intended function..Thermocouples are built to survive for a long period, however not as long as the device for which they are intended to be used.As a result, you may not need to change yours as regularly.

What is the difference between the Type J and Type K thermocouple?

The Type J and Type K thermocouples are two of the most regularly encountered types.Type J thermometers are comprised of iron and a nickel/copper alloy and are capable of measuring temperatures ranging from 0 to 816 degrees Celsius.They are accurate at the temperatures they claim to be at and are reasonably priced.It is comprised of chromel and a nickel/aluminum alloy, and it is known as a Type K thermocouple.Though more expensive than the Type J thermocouple, it is more adaptable since it can measure a greater range of heat between 0 and 1260 degrees Celsius, making it a more cost-effective alternative.

How To Clean the Thermocouple on a Water Heater

Whether the hot water temperature setting on your washing machine is not working, you’ve been washing your dishes with tepid water, or you’ve been taking the dreaded cold shower, it’s likely that your home’s water heater is not performing properly. If you have a gas water heater, a corroded thermocouple might be the source of your problems.

What is a thermocouple and why does my water heater need one?

Gas water heaters that rely on a pilot light to ignite the burner will also be equipped with a thermocouple or thermopile to monitor the pilot’s performance (a thermopile is, essentially, multiple thermocouples connected in a series making the component more sensitive than a single thermocouple).Whenever the pilot light is extinguished, the thermocouple works as a safety measure, stopping the gas valve from opening and potentially flooding the area around the water heater with natural gas, as is the case when the pilot light is out.A malfunctioning thermocouple, or one that is just filthy, may prevent the gas valve from opening or the pilot from remaining lighted on a constant basis.It is as a result of this that the burner assembly does not generate a flame and that the water in the tank remains unheated.Be advised that if the pilot light goes out on your water heater, you will need to relight it according to the manufacturer’s recommendations.

• Newer models of water heaters will feature a pilot setting on the gas valve, as well as a spark electrode to ignite the pilot when turned on.
• If you have an older model, the pilot setting will be available, but you will have to manually relight the pilot with a long match or lighter.

Accessing the thermocouple

• It is common for the thermocouple to be positioned on the burner assembly, which is located at the bottom of the water heater tank. However, depending on the kind of your water heater, the procedures you must do to reach the thermocouple will differ. However, the following are some basic principles you may follow: Check that the water heater’s power wire is disconnected and that the gas supply is turned off prior to starting
• Remove the burner access cover and, if required, unthread any mounting screws that are in place.
• After that, remove the nuts or screws that are holding the burner plate in place.
• Remove the nut from the burner supply tube in order to disconnect it from the gas or control valve. Keep in mind that you may also need to remove a pilot supply tube from the system.
• Release the thermocouple if needed by your model by disconnecting any wires from the valve and unthreading the nut holding the thermocouple in place.
• The vapor sensor should be detachable from the tank base if applicable.
• You may now remove the burner component from the tank in order to have access to the thermocouple, if necessary.

Cleaning the thermocouple

• Using Emery cloth sandpaper, gently wipe the end of the thermocouple to remove any dirt or buildup that may have formed. Additionally, you should clear up any corrosion that may have formed where the power line joins to the thermocouple terminal if it exists. Keep in mind that you may need to remove the thermocouple from the burner assembly in order to completely clean it. Remove any leftover debris from the component by wiping it down with a lint-free cloth. If necessary, attach the thermocouple to the burner assembly using a screwdriver. Reinstall the burner assembly in the tank, ensuring sure that the burner tube is supported by the bracket if one is present.
• Thread and tighten the mounting nuts or screws to ensure that the burner plate is securely attached to the storage tank.
• If required, reattach the vapor sensor to the tank’s bottom base.
• Reinsert the wires into the gas valve and, if necessary, tighten the thermocouple to the valve.
• The burner supply tube, as well as the pilot supply tube, should be reconnected to the valve if necessary.
• Make any necessary repairs to the burner access cover and tighten it down.
• Reconnect the gas supply and plug the water heater’s power cable back into the wall outlet.
• Test the water heater to see if it is heating the water as planned by relighting the pilot light.

It is possible that your water heater is not heating up correctly because the thermocouple has become rusted and damaged. It is a thermocouple that detects the presence of the pilot light and allows the water heater to regulate its internal temperature. How to clean a thermocouple on a water heater is covered in this section. This is a project that even the most inexperienced DIYers can do. What exactly do you require? Lint-free cloth
• sandpaper made of Emery cloth
• an adjustable wrench

Water Heater Thermocouple Cleaning in 5 Steps

1. Shut down the gas input valve for your own safety! Reduce the amount of fuel that is supplied to the water heater. When working on a water heater, the first step is usually to turn it off. If it’s an electric device, turn off the power. In this particular instance, it is gas, and you must turn off the gas valve.
2. Remove the burner assembly and take a picture of it before you start so you can remember how it should appear after you’re finished. It will be necessary to detach the burner component from the control center with the use of the wrench. It’s related in three different ways (thermocouple, main supply tube, and pilot supply tube). It should be possible to move the complete assembly out of its container after they have been separated.
3. Clean the thermocouple – sand the ends of the thermocouple with the emery cloth sandpaper before wiping it down with the lint-free cloth to finish it off. Hopefully, you will be able to reach the ends of the thermocouple without having to remove it from the assembly, but it is possible that you will have to do so. If you do, be sure to put it back together precisely the way it was before you started. Take a photograph
5. (Optional) Clean the burner – while you have the burner out, this is a great time to scrape any debris off the top of the burner. Eliminate any impediments so that it may operate more efficiently.
6. Replace and reattach the burner component – do you recall the image you snapped of the process? When you’re finished, you want everything to appear exactly the same as it does now. Replacing the three lines to the control center on your water heater tank is a simple procedure.
7. Light the pilot – You must first open the gas valve, then light the pilot and adjust the temperature dial to the appropriate setting (we recommend no hotter than 120-degrees F). You should be able to resume operations after all of this is completed.

Now What?

1. Allow enough time for your water heater to warm up.
2. If it’s functioning, that’s fantastic!
3. Ultimately, if the thermocouple is still not functioning, you may have to spend the money on a replacement.
4. The good news is that PlumbersStock provides an extensive assortment of water heater components.
5. When you receive your replacement thermocouple, you may refer to our article on how to replace a water heater thermocouple.

How To Clean A Thermocouple On A Gas Water Heater: Step By Step Guide

1. Gas water heaters, as well as the thermocouple that regulates the flow of gas through them, are essential components of your home’s heating system.
2. In addition, they require periodic maintenance in the same way that all other appliances do.
3. This ensures that the gas water heater is operating properly and that no potentially hazardous gases are seeping into your house.
4. So, what is the best way to clean a thermocouple on a natural gas water heater?
5. To clean our thermocouple, I use the following procedure: Cleaning a thermocouple requires the use of steel wool or 60-grit sandpaper as well as a clean cloth.

Before you begin, cut off the gas supply and remove the thermocouple, which you should polish with steel wool or sandpaper before wiping it down with a towel to remove any residue.Every six months, I clean our thermocouple to keep it from being coated with soot and dirt.If you are unable to remove your thermocouple without first removing the burner assembly, you should contact a plumber immediately since your entire burner assembly may need to be repaired or replaced.Depending on how much soot your thermocouple has accumulated from the flame, it may begin to oxidize.This can result in the thermocouple breaking down, which might result in a large explosion or possibly a fire danger on the scene.

1. It is not a glamorous profession, but it is one that is very necessary.
2. Do you want to know how to clean the thermocouple on your gas water heater?
3. It’s simple, and this step-by-step instruction will take you through the process step by step.

We will also go into further detail about how thermocouples function and how to keep them in the best possible condition.Please continue reading!

What Is A Thermocouple?

1. A thermocouple is a tiny device found towards the bottom of gas water heaters.
2. It measures temperature.
3. These devices regulate the amount of gas that should pass through them in order for them to function properly.
4. It then makes use of this process to heat up enough hot water to meet the demands of your home.
5. This little gadget provides an electric current to the pilot light, which allows it to remain illuminated.

If you don’t clean and replace the thermocouple on a regular basis, corrosion can create a build-up of contaminants.As a consequence, you may find yourself in potentially harmful circumstances that you might have simply avoided.The most common cause of a malfunctioning water heater in the houses that I have evaluated is an improperly maintained thermocouple.If you are planning to sell your house, having functional and well-maintained appliances, such as water heaters, may increase the value of your property significantly.Typically, the thermocouple device does not function on its own.

1. However, it is used in conjunction with another gear known as the standing pilot.
2. When the appliance is in use, the standing pilot is a little flame that remains lit during the operation.
3. As a result, when the pilot light is turned out, the water is no longer heated.

The thermocouple must be in good working order in order for the pilot to remain operational.It is the principal means by which the sensor attached to the pilot receives an electric current that allows it to remain operational.The sensor is located on the gas valve, and it provides a signal to the pilot to keep the pilot light on at all times.The thermocouple is made up of two metals, which allows it to function as a probe that generates voltage when two wires are heated.The Seebeck Effect is a scientific phenomena that explains why this is happening.

Are Thermocouples Universal?

1. Although thermocouples are not universal in nature, some particular versions are compatible with the vast majority of gas water heaters on the market.
2. It is possible to purchase so-called ‘universal thermocouples’ for a reasonable price online or at home supply stores, as well as most hardware and department stores.
3. Consider the length and kind of one before acquiring one.
4. Thermocouples may, in rare instances, fail to function properly in conjunction with other safety components.
5. In these rare instances, a malfunctioning thermocouple might prevent the gas valve from functioning properly.

In most cases, this is not a concern since other safety devices will detect and shut down the system before any damage is done.When these, too, fail, the situation becomes problematic.For example, if both fail to operate properly, you may still be able to receive gas flowing into your home despite the fact that one of them is failing – only this time without being monitored by either of them.

7 Easy Steps In Cleaning Your Thermocouple

Step 1: Prepare The Tools

• Listed below are some of the products you’ll need before starting the cleaning process: A multiway wrench is the tool that will assist you in unscrewing all of the bolts and nuts across the complete system.
• A screwdriver: This is used to loosen any screws that have become too tight in the system.
• An emery cloth is a tool that looks similar to a nail file, except it has a cloth backing. This is used to sandpaper the surface of the thermocouple in order to remove any soot that has accumulated. It also eliminates any oxidation coatings that may have formed.
• After you have finished rubbing away all of the build-up with the emery cloth, you should use this lint-free fabric to finish the job. Because it avoids any possibility of residue lingering on the thermocouple after it has been cleaned, lint-free cloth is the ideal choice.
• Fine grit sandpaper or steel wool: A brush can be used in place of steel wool if you don’t want to use steel wool. This is the final piece of equipment that you will use to dust off any leftover particles from the thermocouple’s surface. The remaining parts of the water heater assembly can also be cleaned with this product.

Step 2: Disconnect The Water Heater Gas Supply

As a result of the fact that certain gas water heaters have two supply injectors, it is better to switch them off simultaneously. When dealing with a gas-powered water heater, remember to always keep your safety in mind. In addition, keep any open flames or sparks to a minimum. If there is an excessive amount of gasoline in one region, this might result in an explosion.

Step 3: Disassemble The Water Burner

1. If your heater has an access lid, you must first remove the mounting screws from the heater.
2. Then, loosening and removing the nuts that hold the burner plate in place is the next step.
3. A few of turns of the screwdriver will be enough to release any threaded linkages that connect the component to other components.
4. If there is anything else hooked into your control center, make sure to unhook them as well.
5. By gently tugging on any protruding connections, you may accomplish this goal.

If they don’t come apart easily, apply some pressure to their release levers while gently tugging at each wire at the same time until they finally break free from one another’s grasp.Remember not to tug on them with undue force or drag them out of their natural position.This is necessary since else you will simply wind up causing damage to anything.Check the base of your tank to check if it is equipped with a vapor sensor.If this is the case, remove it.

1. Remove the burner installation from the water heater in order to have access to the thermocouple.

Step 4: Sand The Thermocouple

1. Sand the thermocouple ends with an emery cloth to make them smooth.
2. This can help you get rid of any persistent stains you may have on your clothes.
3. This will aid in the preservation of a clean sensing region, which will be beneficial while heating water in the future.
4. Before beginning the cleaning procedure, inspect the terminal and power cable for corrosion and remove it with a clean cloth.
5. Complete the process by wiping off all of the sanded surfaces with a clean microfiber towel to verify everything is in proper operating condition.

Step 5: Cleanse The Burner

1. It is also important to clean your burner if you want to save money on your energy costs.
2. If you look within those ports or openings, you’ll be shocked at how much junk may gather.
3. In order to remove any dust that may have settled in these crevices while the steel wool and emery cloth are doing their magic scouring, a tiny brush should be used to remove any dust that has settled in these crevices.
4. Improved efficiency as well as general safety inspections will be made possible as a result of this.

Step 6: Reconstruct The Gas Water Heater

1. To guarantee safety, return the burner unit to its original place in the tank and check that it is firmly balanced on its bracket.
2. Before going on to the next stage of attaching other components, make sure that all of the mounting screws or nuts are tight.
3. Reattach any wire that was removed during the disassembly process, as well as any external components such as internal sensors that were previously removed.

Step 7: Turn On the Gas Water Heater

1. To keep your water heater functioning well and save money on gas, you should adjust the temperature setting to between 120°F and 140°F on a regular basis.
2. Turn off the power or disconnect it if there is a cord before you begin working with the item to ensure that electricity does not flow through it while you are working with it.
3. Then, reconnect the natural gas supply line before manually re-igniting the pilot light to ensure proper operation of the appliance.
4. Make sure you don’t go above 160 degrees Fahrenheit since at these temperatures, corrosion may begin to form inside your apparatus.
5. As a result, there may be possible leaks in the pipes, as well as other safety concerns to consider.

Carbon monoxide poisoning and fires caused by spontaneous combustion are examples of such dangers.

How Do I Know If My Thermocouple Is Bad On My Water Heater?

1. Soot, dust, and debris may accumulate on the surface of a thermocouple over time.
2. This build-up is the most common reason of the thermocouple not sensing heat and, as a result, not functioning properly.
3. As a result, the sensor within the device is receiving incorrect values, which is undesirable.
4. Finding out if the thermocouple in your gas water heater is faulty demands a keen eye and a lot of patience.
5. You must keep an eye out for warning indications.

It’s also necessary to clean, repair, or replace the thermocouple if you see any of the following signs:

Water Temperature Drops

• If you observe a reduction in water temperature or if you are not getting enough hot water, it is possible that the thermocouple is clogged with debris. The thermocouple may also be the source of the problem if you discover that there is no hot water at all in your home. When the thermocouple stops working, the pilot is turned off as well. Because of this, the burner does not light, and the water does not heat as a result. There is, however, a catch: This indication might be generated by another defect other than a faulty thermocouple. In any case, because we’re talking about a thermocouple, here’s how you may determine whether it’s to blame for the lack of hot water: Manually lighting the pilot is your first attempt
• follow along with the directions provided on the tank.
• If the pilot light comes on but the flame goes out as soon as you release the switch, it is a clear indicator that the thermocouple has failed
• however, this is not always the case.

Irregular Thermocouple Volt Readings

• 30 to 40 millivolts is the optimal reading for a thermocouple that is in good working order. And this is the reading that appears when the pilot is turned on. Even if you have a multimeter at your disposal, you will want assistance to conduct this test. Here’s how you can put it to the test: To begin, remove the thermocouple from the gas valve by unscrewing it.
• Next, you’ll need to calibrate your multimeter so that it can read millivolts.
• The person assisting you should maintain the gas control knob pressed in to keep the pilot light on. You should maintain this position for around one minute to ensure that the probe is properly heated.
• Then, with one lead shaft attached to the thermocouple and the other end attached to the multimeter’s connection, you’re ready to go.
• If you receive a reading that is less than 25 millivolts, the thermocouple is defective
• otherwise, try another one.

The Thermocouple Is Loosely Attached

1. Occasionally, problems might emerge as a result of a thermocouple that is not securely connected.
2. And it is for this reason that it must be the first item that you confirm.
3. You must tighten a thermocouple using a wrench in order for it to be correctly set.
4. Applying too much pressure will result in the nut being useless as a result of the excessive force used.
5. Once you’ve tightened it down sufficiently, try igniting the pilot flame again, but keep an eye out for any smoke that may come out of the pilot.

If this occurs, please replace your old one with a new one that is similar to it.

When Should You Replace A Thermocouple?

1. You should replace your thermocouple when there is no hot water running or the readings on the multimeter are below 25 millivolts.
2. You should also replace it if the accumulation of dirt on the thermocouple has become too large to be repaired and is interfering with its operation.
3. The following indications should also indicate that your thermocouple is too damaged to be repaired and that you should have it repaired instead: No Hot Water

When your gas water heater fails, it will have an impact on the entire home.. You won’t have any hot water for cooking or cleaning up after supper, and you’ll have to take cold showers, which will be difficult in the winter because of the chilly temperatures. Your thermostat becomes overheated.

1. One of the most hazardous aspects of a defective thermocouple is that it may cause your thermostat to become too hot, which might result in a full-blown fire.
2. This has the potential to be disastrous.
3. Flawed wiring is one aspect that contributes to this fire outbreak since it can result in electrical fires or even tiny, unintentional blazes as a result of static electricity build-up.
4. Increased Electricity Bills

If you fail to discover a damaged thermocouple, you might end up in this situation. When it gets too late to correct the problem, the situation deteriorates, and energy spikes become more frequent as a result of decreased efficiency rates. The Smell of Natural Gas

1. One of the tell-tale indicators that your thermocouple needs to be changed is the smell of gas coming from it.
2. The last thing you want to deal with is a buildup of dangerous gases in your home or office.
3. If you utilize natural gas or propane, breathing high amounts of these gases is harmful to anyone’s health, regardless of their age.
4. In addition, these gases might be the source of an explosive fire.

Can You Replace A Thermocouple Yourself?

• Yes, it is possible. However, in order to complete the task properly, you must possess some fundamental abilities. It will cost you roughly $20 and will take you approximately 45 minutes to complete the entire exercise. Overall, the following is a straightforward way to replacing a thermocouple on your own: Gather all of the tools you’ll need: To do this task, you will need an adjustable wrench as well as a collection of different wrenches for different bolt sizes. It would be helpful if you could also bring the new thermocouple that you are replacing.
• Disconnect all electrical and gas supplies: In order to ensure the safety of everyone, you must unplug any gas and electrical inlets. In addition, make certain that the water heater is disconnected and turned off. The following step is to remove any connections to the complete burner unit by unscrewing any bolts that may be present.
• Remove the thermocouple from the burner unit by disassembling it as follows: Following the removal of the burner, you will need to remove the thermocouple. Make certain that the new water heater is the same model as your existing gas water heater
• Replace the thermocouple as follows: Reverse the procedures you did to deconstruct the system, then reconnect the complete system with the new thermocouple you installed.

It is important to note that when replacing the thermocouples, you should also clean the complete system. Follow the procedures we described before to ensure that the work is completed thoroughly.

Can Water Damage A Thermocouple?

It is important to note that while replacing the thermocouples, you should also clean the whole system. Keep in mind the stages we outlined before in order to do a comprehensive job.

Take Away

1. It is critical that your thermocouple is kept clean in order for it to function properly.
2. Because your gas water heater represents a big financial investment, you want to make certain that it operates well and lasts as long as possible.
3. The thermocouple should be cleaned out about once every six months or so to keep the machine in good working condition.
4. It is possible to employ someone who understands what they are doing if you do not know how to do it yourself!
5. Because of the greater demand levels associated with a dirty-running appliance, you will see an increase in your monthly electricity bill.

As a result, keep this in mind while reviewing your electricity costs each month.After everything is said and done, be sure that no new regulation regulating gas water heaters is in effect before dealing with anything that involves them, such as changing a thermocouple.DISCLAIMER: The information provided on HomeInspectionInsider.com is not intended to be professional guidance.Before beginning any job, you should contact with a competent expert and verify that all necessary permits have been obtained.It is owned and operated by Hubert Miles who is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by placing advertisements and links on their websites that direct traffic to Amazon.com (hereinafter referred to as ″Amazon.com″ or ″Amazon.com Associates Program″).
