[Specific Application] The 619154 thermocouple is compatible with Norcold N300 and N300.3 series RV refrigerators. Fits both 2-way and 3-way model Norcold N300 refrigerators. [Strong Function] The thermocouple signals the gas valve that the pilot is lit, allowing it to remain open. It functions as a safety device by detecting the heat of the flame and generating a voltage to keep the gas flowing. [Great Feature] The 619154 thermocouple converts heat energy from the pilot light into an electrical current, which opens the solenoid valve and allows gas to flow to the appliance. [Superior Material] Made of high-quality metal material. Offers strong durability, corrosion resistance, and anti-rust performance. Enhanced quality enables longer service life.
