The Fix: Pilot Light to Gas Fireplace Won’t Stay Lit This can be an indication that your fireplace thermocouple is either bad or worn out. However, if your pilot is lit but the gas fireplace isn’t, then there’s probably a problem with your thermopile.

Why does my pilot light go out when I turn it to on?

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 gas fireplace light and then go out?

A common problem with gas fireplaces lies in the components called the ignition assembly. When a fireplace refuses to remain lit, there’s probably an issue in one of the several pieces that make up the ignition assembly, which are: the pilot light assembly, pilot tubing, thermocouple, and thermopile.

How do I clean the thermocouple on my gas fireplace?

How to Clean the Thermocouple in a Gas Fireplace Turn off the fireplace gas valve and remove the front panel from the fireplace. Find the thermocouple, which is located next to the pilot light and looks like a small straight pipe. Use a can of compressed air to gently blow away any dust and dirt from the thermocouple.

How much does it cost to replace a thermocouple in a gas fireplace?

When replacing a thermocouple or thermopile with the help of a professional, you can expect to pay between $150 and $250.

How do I stop the wind from blowing out my pilot light?

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.

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 do I know if my thermocouple is broken?

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.

Why does furnace pilot go out?

The thermocouple on your heating system is a safety device that determines whether or not your furnace pilot light is lit. A thermocouple that is dirty or malfunctioning will often shut off your gas supply in error, causing the pilot light to go out and your furnace to stop working.

Why does my fire keep going out in my fireplace?

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.

How long does a thermocouple last on a gas fireplace?

How to Tell if You Have a Bad Thermocouple? Thermocouples can last up to 10 years if properly installed and maintained, while furnaces can last 15-20 years, although either may wear out sooner in multifamily units.

Can you clean a thermal coupler?

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. Cleaning a thermocouple is not a fix for an issue, such as inaccurate readings.

Can you light gas fireplace without pilot?

Natural gas appliances and fireplaces have traditionally used a standing pilot light to ignite the flame/heat source. Because these systems do not rely on external electricity, they work seamlessly even if the power goes out for an extended period of time. This does require electricity to start up.

Can wind cause a pilot light to go out?

Being exposed to drafts or wind – Most pilot lights simply blow out. Luckily, this is one of the easiest problems to fix.

Should the pilot light always be on in a gas furnace?

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.

Why do thermocouples go bad?

Soot buildup on the thermocouple may block the flame. Under constant exposure to a hot flame, a thermocouple wears down over time. Even a slight residue can make the thermocouple malfunction.

Can I replace a thermocouple myself?

1 cause of pilot lights that won’t stay lit is a worn-out thermocouple. It’s easy to replace and a new one costs $5 to $10. Then detach the thermocouple from the burner and take it with you to the home center or hardware store to ensure you buy the right replacement.

How much does it cost to fix a pilot light?

You can replace the thermocouple yourself for around $20. If you hire a contractor to do the work, it will cost $45 to $150. A contractor fixing the thermocouple and the pilot light will usually be able to replace both in one hour, meaning it will be $45 to $150 for both.
