Guide to Replacing a Thermocouple on a Hot Water Heater

The thermocouple refers to a thermoelectric device that turns off the gas when the pilot light is off. In a nutshell, it’s a short piece of tubing that extends from the gas controller to the pilot. The pilot end of the thermocouple and the pilot are placed alongside each other in a bracket that’s attached to the burner. When you have a hot water heater with a pilot light that can’t seem to remain lit, it’s most likely due to a faulty thermocouple.
