Web29 sep. 2024 · How many millivolts should a thermopile produce? Just like the thermocouple, the thermopile can be read with a multimeter to check if it’s the cause of the problem. 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. Can you … WebHow many millivolts are in a gas fireplace? The pilot flame warms the thermocouple and thermopile sensors. When heated, the material in the sensors creates a small amount of voltage. The thermocouple generates about 20-30 millivolts, enough electricity to keep the part of the gas valve that controls gas flow to the correct position.
