Thermopile testing

The thermocouple compared to the thermopile.

WebbThe image shows that the pilot light is heating up the thermopile. Thermopile is designed to generate about ½ Volt(500-750 millivolt) of electricity if it’s heated for about 2 minutes. The pilot light, a small flame, delivers this heat.. Once the wall switch is closed, the electricity goes from the thermopile to the gas valve and turns the gas valve on. WebbThe process for testing a thermopile is very much the same, except you connect the leads to the wire connections on the gas valve. The reading on the meter must be approximately 350 millivolts after the pilot flame has been burning for two minutes. Anything that is less indicates the thermopile is bad. Final Thoughts
