The Dometic thermocouple (Part# 407144377) is a critical temperature-sensing component for Dometic RV refrigerators. This 350mm thermocouple monitors cooling performance and signals the refrigerator's control board to maintain proper internal temperatures. If your RV fridge isn't cooling evenly or the compressor cycles erratically, a faulty thermocouple is often the culprit.
