Why does my gas fireplace keeps going out?

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.

What does it mean when your gas fireplace light won’t stay on?

You checked your pilot light and reset it, but the fireplace still won’t run continuously. If this happens, be sure to check your pilot light again. You might find that you have an even bigger problem with your unit. What does it mean if your gas fireplace pilot light won’t stay lit?

What should the flame be on a gas fireplace?

Apart from your pilot being lit, the flame must stay a steady blue. Your pilot should be about 90 percent blue, with very little yellow. It should also be touching the surrounding sensors such as the thermocouple and thermopile.

What should the voltage be for a gas fireplace to stay lit?

Three hundred millivolts or higher voltage is a sign of a good thermopile. A reading below 300 millivolts would require you to replace the thermopile. It’s always a good idea to test your thermocouple with a multimeter to rule out the possibility of it being the reason behind your gas fireplaces not staying lit.

Why is my gas fireplace not staying on?

Faulty wall switch may be the cause why your gas fireplace won’t stay lit. This is a common problem for most gas fireplaces. Thermocouple and thermopile are directly connected to the wall switch. When your wall switch is flipped on it transmits current that triggers the flame.

Why you should turn off your gas fireplace pilot light?

Pilot OFF: No gas is being wasted so you are conserving energy and saving money! No heat is being generated by the pilot so the glass door on your fireplace will not be warm to the touch. With the pilot off, there are still trace amounts of gas molecules in the burner and pilot tubes of your fireplace.

Should I keep the pilot light burning on a gas fireplace?

Leaving the gas on keeps this compound moving out of the tubes. Keeping the pilot light on will also keep moisture out of the unit and in turn, help prevent corrosion. Plus, if the fireplace is located in the basement, it may also help to reduce humidity levels.

Why will gas logs not stay lit?

If you can’t keep your gas logs stay lit, likely your pilot light (flame) is poor or that your thermocouple is bad. Check that your flame is blue and check your thermocouple for voltage. These problems could be manifestations of more serious issues.
