A fundamental safety device of the gas heating system is the thermocouple. Mounted directly in the pilot flame, the thermocouple is an electric sensor that detects heat and controls the gas valve. If the pilot light is on, the thermocouple maintains the fuel supply open, but if the pilot light is out, the device senses the lack of flame and switches the gas valve closed. Consequently, the function of the thermocouple is to determine whether it is safe to keep the gas flowing through the system, or not.

Pledge: We will test the thermocouple for proper responsiveness to and, if necessary, replace it.
