Thermostatic Switches

All Pro Truck Parts stocks thermostatic switches for heavy-duty truck air conditioning systems. Thermostatic switches cycle the AC compressor on and off based on evaporator temperature — a failed switch can cause the evaporator to freeze up or the compressor to run continuously. We carry replacement thermostatic switches for the most common Class 6 through Class 8 truck AC systems.
