Can You Clean A Hot Water Heater Thermocouple?
Yes, you can clean a hot water heater thermocouple. Over time, dust, dirt, and other debris can build up on the thermocouple, leading to malfunction or failure. To clean it, turn off the gas to the hot water heater, remove the thermocouple, and gently clean it with a piece of fine-grit sandpaper or a soft-bristled brush. Do not use any harsh chemicals or abrasives on the thermocouple, as this can damage it. Once it is clean, reattach the thermocouple and relight the pilot light.
