Gas fireplace shuts off and pilot goes out.

In this hvac training video i show up close how the thermocouple pilot light and gas valve work on a water heater furnace fireplace as well as other ap. Gas fireplace won t stay lit but the pilot light does. Why does my gas fireplace go out after only a few minutes of running. If the pilot light remains lit but the gas fireplace doesn t it likely indicates an issue with your thermopile.

If the thermocouple fails to shut off the gas all the gas flowing through the furnace could get into your home. I have replaced the valve the thermopile and over temp sensor. It starts up fine runs for about 5 10 minutes than completely shuts off pilot and all. Crack a window near the fireplace and see if there s a difference.

This in turn makes the gas valve shut off. Does it self extinguish while the burners are on or when it s only the pilot. The thermocouple safeguards against a catastrophic buildup of gas. The butane lighter is located near the center of the gas logs.

However if you find that your gas fireplace or similar appliance has a pilot light that won t stay on even after consistently being fixed or relit one of these issues could be the reason.

Gas fireplace shuts off and pilot goes out after that you need to insert the butane lighter into the gas tube. The flame lifts away from the thermocouple and causes the temperature on the tip of the thermocouple to drop.
