Water Heater Thermocouple Cleaning

Thermocouples on water heaters are delicate parts that are easily damaged by the elements of water heating systems. They can be cleaned by removing their cover to gain access to the thermocouple. To do this, you can use an emery cloth or steel wool. To clean them effectively, you should make sure to use abrasive materials or cloth. Avoid using flammable products or harsh chemicals.

Remove Burner Assembly

The thermocouple is connected to the thermostat and may be attached to a vapor sensor. Unplug the vapor sensor and disconnect the wires from the thermostat. Next, remove the burner assembly and the thermocouple. Take pictures of the thermocouple before disassembling it.

Remove Screws

After removing the screws, you can use an emery cloth to sand the ends of the thermocouple. This will remove any stubborn stains and leave the sensing area clean and clear. Then, wipe the exposed areas with a microfiber cloth. Using a steel pool will help you remove stubborn stains and dirt. Be sure to turn off the gas supply and unplug the water heater before tackling the task.
