How to Relight Pilot Light on Water Heater

If your pilot light is off, there are some steps you can take to relight your pilot light. Some of the steps you need to perform include checking the shut off valve, replacing the thermocouple, and ensuring that the pilot will stay lit.

Check the shut-off valve

If you have a gas water heater and your pilot light is out, you may need to check the shut-off valve. Typically, this is located near the gas meter. There are also some water heaters with a control panel tucked away at the base of the unit. You can use a wrench to access it.

While you are at it, you might want to check the temperature gauge, which is typically located on the outside of the unit. This will give you a good idea of how hot the water is.

When a pilot light goes out, it’s important to relight it. Usually, this is done by turning off the gas supply. Turning off the gas allows the flow to clear, while also allowing you to see if you have any gas leaks.

For the most part, you can do this yourself. However, if you’re having problems, you might need to call a professional. The relighting process is not as simple as it sounds.

The best part of this process is that you don’t have to replace the entire unit. Often, you can simply clean or replace the thermocouple, which is the device that controls the flow of gas into the unit.

A clogged pilot tube will cause the pilot light to go out. In order to clear out the pilot tube, you may have to do several cleanings. To relight the pilot, you may need to turn off the gas, use a long lighter, and hold the light to the gas for a few seconds.

The water heater may be out because it doesn’t have enough combustible air. This can lead to buildup of carbon monoxide, which can be deadly. If this is the case, you may need to install a carbon monoxide detector nearby.

Depending on your water heater model, you may be able to relight the pilot by pressing a button or opening a door. Be sure to follow the instructions included with the heater. By following these instructions, you’ll be able to relight the pilot safely and effectively.

Using a temperature control gauge can help you relight the pilot. Some models have a ‘ignite’ button on the control panel.

Replace the thermocouple

If your water heater’s pilot light does not work, you may need to replace the thermocouple. Thermocouples are a small device that monitors the pilot light and shuts down the gas supply if the pilot light is not working. It’s a quick and easy job, and you can have it done in less than an hour.

There are several things you need to know to safely replace the thermocouple. First, you need to disengage the gas supply from the control panel. You can do this with an adjustable wrench.

Next, you need to clean the pilot tube. This is the part that connects the burner assembly to the gas control valve. If it is clogged, it will cause the pilot light to fail.

After cleaning the pilot tube, you should make sure that it is still in good condition. If it is not, you will need to call a professional to fix it.

Ideally, you should have your local gas company out to repair your unit. They can help you with locating the defective part.

Once you have the part replaced, you need to relight the pilot. Sometimes, you need to light the pilot several times to get it to work.

In case the pilot does not light, the reason may be because the thermocouple is no longer able to detect the flame. It’s possible that the pilot has a hole that is too small for the thermocouple to fit into. However, it’s more likely that it’s worn out.

You can test the thermocouple to ensure that it’s in good condition. A multimeter is a good way to do this.

Another way to test the thermocouple is to use dishwashing liquid. This can be used to check for leaks and connections around the burner.

You can also take the thermocouple to your local home center or hardware store. Depending on the type of thermocouple you have, you can usually replace it in under an hour.

Before removing the thermocouple from the water heater, it’s important to make sure it is cool. It’s also essential to not bend the connection between the thermocouple and the pilot.

Determine if the pilot will stay lit

If you have a standing pilot light on your water heater, you might wonder if it will stay lit. You can determine this by using a multimeter to test the thermocouple.

The thermocouple is a small copper wire that senses the heat of the pilot light. It is used to automatically turn off the gas if the flame is out of commission.

When the pilot light is malfunctioning, it is likely due to a faulty thermocouple. This is the most common and easiest fix. However, if the thermocouple is shattered, or you have a closed burner chamber, you will need to call in a professional.

Another common cause of a malfunctioning pilot is a clogged orifice in the pilot tube. This prevents the flame from engulfing the thermocouple. Using a slender needle to loosen this obstruction will allow the gas to flow properly.

There are also a number of other reasons the pilot light may not be burning. A breeze through an open window can snuff it out, as can a downdraft in a vent pipe. Other causes include a broken or misaligned flame sensor.

Most modern water heaters are equipped with a thermocouple device. Although this is a very simple device, it is not without its flaws.

Keeping this piece clean is one of the best ways to extend the life of your heater. The best way to do this is to use a slender needle to gently unclog the pilot tubes. After removing any debris, use rubbing alcohol to wipe the orifice clean.

Once the pilot is relighted, it should stay lit. Repeat the process a few times to ensure the pilot is working correctly.

The water heater pilot light should be a blue color. If you have a manual heater, you can relight the pilot using a wand lighter. Depending on your model, you may have a red or black button on the pilot knob.

If your water heater is showing signs of having a problem, you should turn the temperature control knob to its lowest setting. Keeping the temperature below 120degF will ensure your heater is safe to operate.

Safety considerations

Relighting the pilot light on your water heater can be an easy task to perform if you know what to do. However, there are some safety considerations you should keep in mind.

First, make sure the gas in the room is safe to ignite. If the gas isn’t, you may want to consider calling a plumber to fix it. Once the gas is clear, relighting the pilot can be done.

You should also look out for warnings such as blowing sounds, hissing, or a strange smell. If you notice these symptoms, turn off the gas valve and call a professional right away. It’s also a good idea to open windows and doors to let in air.

A faulty thermocouple or a pilot light that is too low can also cause the pilot to go out. The thermocouple senses the flame and shuts off the gas supply when it goes out.

An old water heater may require some familiarity with how the pilot works to relight. This is especially true if it’s a gas-powered unit. Fortunately, most newer models have a built-in safety mechanism that prevents the heater from igniting.

Before relighting the pilot on a gas-powered water heater, it’s important to follow the manufacturer’s instructions. These will help you relight the pilot safely and effectively.

Having a gas leak is very dangerous, and should only be handled by professionals. The process of repairing a gas leak requires turning off the gas valves and removing the pilot light window.

Usually, the pilot light is located underneath the gas control valve. It can be seen through a small glass window. However, some hot water heaters have a cover over the light.

To relight the pilot on a gas-powered water heating unit, first turn off the gas. This will give the residual gas time to disperse. After 10 minutes, you should be able to see the pilot.

If you’re having problems with the pilot, contact your local plumbing company to repair the problem. A qualified plumber can inspect and relight the pilot. Some modern water heaters have a “vacation mode” that will close the gas supply when the pilot goes out.
