Ensure the safety and reliability of your gas fireplace with this high-quality 18-inch 30mV thermocouple. As a vital component of the pilot assembly, this thermocouple acts as a flame sensor, converting heat from the pilot light into a 30-millivolt electrical signal that holds the gas valve open. If your fireplace pilot won't stay lit or your burner shuts off prematurely, a worn or malfunctioning thermocouple is frequently the culprit. This replacement part is designed for precision and durability, providing a fast response time to temperature changes. It is compatible with a wide range of gas-fired heating appliances, including indoor fireplaces, gas log sets, and freestanding gas stoves using either natural gas or liquid propane. The 18-inch lead length offers flexibility for various installation configurations, making it an essential repair part for maintaining consistent warmth and safety in your home.
