Webb7 maj 2024 · Step By Step Thermopile Testing Guide With Multimeter. Here is the step-by-step procedure to check the current in the thermopile of your gas fireplace pilot unit: Step 1: Set the digital multimeter to DC (Direct Current). The multimeter will not read the voltage if you set it to AC (Alternating Current) volts. 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.
