A faulty, misaligned, dirty, or damaged thermocouple is often the culprit behind your pilot light going out. The thermocouple is an automatic safety shutoff device that prevents the gas valve from opening if the pilot light is out.
Why does my pilot light go out when I release the pilot light knob?
The most likely of those is that the thermocouple needs to be replaced. The button you press to light the pilot bypasses the thermocouple. When you release the button, the thermocouple ensures that unburned gas doesn’t get released by shutting off the gas when it’s not heated by the burning pilot light.
Can you turn up a pilot light?
If the pilot flame is too small, you may be able to make it larger by turning the pilot adjustment screw on the valve control counterclockwise with a screwdriver to open it. If this screw isn’t labeled, consult the appliance owner’s manual to identify it.
Can you manually light a pilot light?
Use a grill lighter or long match to light the pilot light valve at the bottom of the oven. Some ovens are designed to be manually lit at each use. In this case, slowly turn the temperature knob while holding the flame to the pilot light valve. Close the oven door after the pilot light ignites.Why won't my pilot light stay lit on my propane heater?
If the thermocouple is too far from the flame, this can cause the pilot to go out and shut down the propane heater; you can fix this easily by moving the thermocouple closer to the flame. The thermocouple could also be worn out, in which case it needs to be replaced.
Can you clean a thermocouple?
Yes, you can clean a thermocouple, but the task must be done with a light touch. Remove the thermocouple from the process assembly, using a steel wool or emery cloth, lightly clean the tip removing any build up.

Why does my pilot light keep going out on my hot water heater?
Your thermocouple senses when your pilot light is burning. … If it senses that your water heater pilot light keeps going out, the thermocouple will shift off the gas supply to the heater. Over time, thermocouples can malfunction, accumulate dust buildup, or the device can get bent away from the pilot light’s flame.Can you fix a thermocouple?
Thermocouples are designed to detect a pilot light’s loss of heat and close the gas valve to prevent a gas leak. Replacing a thermocouple is a relatively easy fix that can take less than two hours.
How do you reset the pilot light on a gas fireplace?Turn the knob from the “Off” to the “Pilot” position. Push in the pilot knob, which manually sends gas into the system. Push the igniter button once every second until it lights. Depending on how long it’s been since the gas fireplace was last used, ignition may take multiple attempts.
Article first time published onShould the pilot light always be on in a gas heater?
Most furnaces with electronic ignition have a device called a hot surface igniter. … The difference is that the flame is only lit (by an electronic spark) when your furnace is ready for a heating cycle. When the pilot light is not needed, it is completely off, saving you money on gas.
Do you smell gas when pilot light goes?
Pilot light safety is important to prevent fire or poisoning from natural gas the pilot burns. … If you smell the “rotten egg” odor of escaping gas, check to see if the pilot light is extinguished. If it is not, turn the gas valve to the “off” position and call your gas company.
How do you adjust a gas flame?
- Light all surface burners.
- Turn the knob on the burner being adjusted to Lo.
- Remove the knob.
- Insert a small, flat-blade screwdriver into the valve shaft.
- Turn the valve to adjust the flame.
- Replace the knob.
How do you know if you have a bad thermocouple?
If you can’t get the flame to light at all, and you’re sure the gas is on, there’s probably an obstruction in the pilot tube. If the flame lights and goes out when you release the gas control knob after holding it in for the recommended 20 to 30 seconds, that’s the sign of a thermocouple malfunction.
How do I stop my furnace pilot from blowing the wind?
You can prevent a faulty pilot light from wind by fixing your thermocouple, gas release, protecting against downdrafts, capping your chimney, and checking your firebox cover.
Why does my gas fireplace keep going out and coming back on?
A thermo pile enables gas to move through the burner system, delivering the gas fireplace’s heat and light. … One of these devices could have gone bad or may have shorted out, causing your fireplace to turn shut down or turn back on at random.
Why does my fire keep going out?
The ‘Fire Triangle’ taught us that fire needs three things to burn: oxygen, heat and fuel. … While the most common causes of log burners going out are insufficient oxygen, fuel or heat, stoves also rely on a properly functioning chimney. The purpose of this is to draw out exhaust fumes that could suffocate your fire.
Should I turn off the pilot light on my gas fireplace in the summer?
Your Utility Bill Perhaps the most important reason to turn off gas fireplace pilot light in summer is because of the money and energy you will be saving. If you leave the pilot light on during the summer it is simply sitting there burning gas, which is wasting gas and contributing to an exorbitant energy bill.
Is a flame sensor and thermocouple the same thing?
People tend to use the terms “flame sensor” and “thermocouple” interchangeably. In truth, while they basically perform the same job, they’re not the same thing. If your furnace uses an electronic controller, it’s got a flame sensor. Thermocouples are used on standing pilot furnaces that have pilot lights.
How do you maintain a thermocouple?
- Do not allow excessive bending of the thermocouples. …
- Use protection tubes for corrosive atmospheres.
- Always inspect protection tubes when changing thermocouples. …
- Do not locate the thermocouple too close to a heating element.
How do I know which thermocouple to buy?
You want to get one that is about the same length as the one you have. They are sold in in 6″ increments for the shorter lengths, 18″, 24″, 30″ and so on. For a water heater, 18″ and 24″ are common, although longer ones are possible. Remove the old thermocouple and measure it to see what length you need.
What do thermocouples do?
A thermocouple is a sensor that measures temperature. It consists of two different types of metals, joined together at one end. When the junction of the two metals is heated or cooled, a voltage is created that can be correlated back to the temperature.
How much does it cost to replace a thermocouple?
It costs $150 to $250 to replace a thermocouple. It checks to make sure the pilot light is on. It will shut the gas off if it’s not.
How much does it cost to replace a thermocouple on a hot water heater?
Thermocouple – $20 to $150 The thermocouple is an apparatus that senses whether the pilot light is lit and triggers the gas control valve. Repairs typically cost about $150 to have it done professionally, though a new thermocouple itself only costs about $20 on average.
Does the pilot light stay on in a gas fireplace?
Most gas fireplaces rely on a “continuous pilot light,” a type of pilot that remains lit so long as gas is flowing to the unit. Some newer, more energy-efficient models rely on an electronic ignition that only lights the pilot when the fireplace itself is turned on.
Does the pilot light always stay on?
A pilot light means heat, and it also means fuel usage. That flame doesn’t stay ignited by magic – it needs gas. Which means as long as that light is on, you’re using your fuel supply to maintain it.
Do you turn pilot light off in summer?
Should I Turn Off My Pilot Light In The Summer? If you have an older furnace, turning off your pilot light can be an excellent idea. A continuously burning furnace pilot light will generate heat and moisture throughout the summer months – in a small amount to be sure, but still undesirable once the weather heats up.
Is it bad if the pilot light goes out?
A pilot light is a small flame that is built into your gas heating appliances, such as a furnace or water heater. … If the pilot light goes out for any reason, the current stops, the valve closes, thus preventing any gas from leaking.
What Colour should a pilot light flame be?
The color of the pilot light should be blue because that means that only natural gas—without any other condensates—is reaching the pilot light through the gas main. The principal chemical compound found in natural gas is methane, and methane burns blue.
Is my pilot light too high?
Next to the “Pilot” indicator on the furnace’s control switch, there is a small screw located near the pilot light-thermocouple assembly. … If it extends well above the thermocouple, it’s too strong. If the flame covers the top of the thermocouple and burns steadily with a yellow tip, that’s just about right.
Why is my fireplace pilot light so loud?
If there is a roaring sound that occurs when the pilot light is on, it is usually because the flame needs to be adjusted. A grinding or shrieking noise is usually caused by a fan or blower. … Newer gas fireplaces with blowers are usually a lot quieter than a lot of older fan systems, which can sometimes be quite noisy.
