Ensure your gas fireplace operates safely and efficiently with this high-quality 22-inch 30mV thermocouple. Specifically engineered for gas fireplaces and stoves equipped with SIT gas valves, this thermocouple acts as a vital flame sensor and safety device. When the pilot light is lit, the thermocouple generates a small millivolt electrical signal that signals the main gas valve to remain open. If your fireplace pilot won't stay lit or the burner shuts off unexpectedly, a worn-out or oxidized thermocouple is often the culprit. This durable replacement part is designed for easy installation in millivolt-controlled heating appliances, providing a reliable connection and consistent heat-to-electricity conversion for residential gas hearth systems. It is an essential component for maintaining the pilot assembly in many leading fireplace brands.
