WebFeb 21, 2024 · The thermocouple stops the flow of gas whenever there is a power outage. It closes the valve of the gas line that provides gas to the pilot light. Therefore, the pilot light goes out when the power goes out. You say that the thermocouple requires [electrical] power to operate. See Above.

WebThe thermocouple is what controls the supply of gas to the pilot light at all times. The thermocouple’s other end, a metal rod, gets pointed right over the flame of the pilot light. The rod reads the flame’s temperature accordingly. The temperature then gets registered by the rod, providing a small amount of voltage to keep the gas supply open.
