How to Test a Thermocouple with a MultiMeter - Heating
So how do you test the thermocouple to see if it is bad or not? You will need a multimeter that will read millivolts (most meters read small voltage like millivolts, which is 1/1000th of a volt) and a source of fire such as a lighter or small torch.
How to Test a Thermocouple: 14 Steps (with Pictures) - wikiHow
Jun 22, 2024 · A thermocouple is a safety device that helps control the gas supply in gas-heated furnaces. When it stops working, the furnace’s pilot light also turns off. For a basic test, attempt to turn on the pilot light again. If you’re still unsure or don’t have a working pilot light, test the thermocouple with a multimeter.
