Gas Fireplace Thermocouple And Thermopile

Cleaning the thermocouple is a pretty simple process but should only be done when the fireplace is turned off and is completely cool.

Gas fireplace thermocouple and thermopile.

This one covers the thermopile wiring on the gas fireplace. Replacing the thermocouple is quick and something you can easily do yourself. It does this by generating a small electric current on the order of. As the heat reaches the second junction of the thermocouple it generates electrical voltage.

If your pilot light stays lit for a few moments but continues to go out after relighting it may very well need the thermocouple replaced. When turned on the pilot in a gas stove generates heat which travels through a thermocouple. The thermocouple on your gas fireplace is a heat sensitive device that keeps the pilot gas tube open while the pilot is lit.

The thermocouple lasts for 10 years or more and when it fails the pilot won t stay lit and the fireplace won t work. The thermocouple on your gas furnace is a heat sensitive device that transmits a small electrical signal to the gas valve to keep it open when the pilot is on. They produce enough current to power up a small circuit board used in conjunction with a more modern electronic gas valve.

The thermopile is the compilation of several thermocouples together. The thermocouple on a gas fireplace may eventually become clogged with dirt and soot which can reduce the effectiveness of the thermocouple and may eventually prevent the fireplace from lighting as expected. Gas fireplaces and fireplace inserts use thermocouples and thermopiles primarily to generate electricity. A gas fireplace thermocouple is a safety device that measures heat and recognizes if a pilot light has gone out shutting down the fuel supply such as gas or propane.
