Why does the pilot light on my gas logs keep going out?

If the pilot light on your gas fireplace won’t stay lit, a very likely culprit is a component called a thermocouple. A thermocouple is a safety device and is a component of the ignition system. Its purpose is to not allow the gas valve to open if the pilot light isn’t lit.

How do I clean the thermocouple on my gas fireplace?

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

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.

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.

What do you do when the pilot light goes out on a gas fireplace?

If you notice your pilot light has gone out, the first thing you should do is shut off the gas feed and wait a few minutes.

Why do my gas logs keep shutting off?

If you get dust in the pilot assembly and the pilot needs to be cleaned out, it produces a “lazy” flame, which will be disturbed by the draught of the main burners. The flame lifts away from the thermocouple and causes the temperature on the tip of the thermocouple to drop. This, in turn, makes the gas valve shut off.

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

How much does it cost to replace a thermocouple? 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.

Why does my furnace pilot light keep going out?

…then you most likely have a dirty or restricted pilot light orifice. You see, the pilot light orifice controls the flow of gas to your pilot light. The pilot light needs a strong flow of gas to make a strong, steady blue flame that the thermocouple can sense. But if the orifice is dirty or restricted, the pilot light won’t light properly.

Why does my water pilot keep going out?

Therefore, a dirty thermocouple might be the reason why your water pilot keeps going out. A layer of dirt and grime can hinder the electric current from reaching the thermocouple. As a result, the gas supply will be cut off and the pilot light will go out.

What does the pilot light on a gas fireplace do?

The thermocouple acts as a safety measure. Its function is to make sure there are no gas leaks if the electric igniter fails or if the pilot light shuts off. While pilot light is a small flame that you can find inside a device, this light is always lit.
