TRUE E800316 Defrost Switch W/3 Wires

The TRUE E800316 Defrost Switch 3 Wires is a temperature-sensitive control component used in commercial refrigeration systems. It is installed in the evaporator defrost circuit and works as a defrost termination switch, monitoring coil temperature during the defrost cycle. When the evaporator reaches a preset temperature, the switch opens the circuit to stop the defrost heater, preventing overheating of the coil and surrounding compartment. It is mounted near the evaporator assembly in refrigerators and freezers and is integrated into the system's defrost control sequence alongside the timer and heating elements to ensure proper frost removal and stable operating temperatures.
