Gas Fireplace Thermocouple And Thermopile

The thermopile is the compilation of several thermocouples together.

Gas fireplace thermocouple and thermopile.

It does this by generating a small electric current on the order of. They produce enough current to power up a small circuit board used in conjunction with a more modern electronic gas valve. 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 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.

Replacing the thermocouple is quick and something you can easily do yourself. Thermopiles are used to provide something like an output in response to temperature. When turned on the pilot in a gas stove generates heat which travels through a thermocouple. This one covers the thermopile wiring on the gas fireplace.

As the heat reaches the second junction of the thermocouple it generates electrical voltage. 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. Cleaning the thermocouple is a pretty simple process but should only be done when the fireplace is turned off and is completely cool. 750mv thermocouple for heat glo heatilator fireplace thermopile replacement fireplace stove accessories for fire gas stoves heat glo gas stoves oven water heater frying furnace 24 aluminum 4 4 out of 5 stars 171.
