Furnace Thermocouple Test. So how do you test the thermocouple to see if it is bad or not? Gas furnace will not light. They are all useful, but the best one is probably the closed circuit. Before attempting any repairs, it’s a good idea to inspect and test your furnace thermocouple. The thermocouple typically needs to heat up for 30 to 60 seconds in order to obtain a proper reading. 30 mvdc is the desired reading, with a swing of plus. Knowing how to test a thermocouple with a multimeter is crucial in diagnosing why a pilot light goes out or won't ignite at all. 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. Before starting the tests, thoroughly clean the part to eliminate any. How to inspect your furnace’s thermocouple. There are three different testing methods that you can use to test your thermocouple. I show how to bench test a thermocouple for a gas.
