Authentic Appliance Parts QP2-4.7 Refrigerator Ptc Refrigerator Start Relay 2 Pin Compressor Overload Protector

The QP2-4.7 PTC Start Relay is an essential compressor protection component for refrigerators. This 2-pin overload protector prevents compressor damage by cutting power during electrical faults or thermal overload conditions. The PTC (Positive Temperature Coefficient) design automatically resets when the compressor cools, eliminating the need for manual intervention.

Compatible with numerous refrigerator models across major brands including Whirlpool, GE, Frigidaire, Bosch, and RCA. Designed as a direct replacement for original equipment manufacturer parts.

Installation is straightforward—simply disconnect power, remove the defective relay from the compressor terminals, and insert the new unit until it seats firmly. Ensure proper polarity alignment with your specific model.

This part helps restore cooling function and protects against repeated compressor failures caused by electrical surges, locked rotors, or inadequate refrigerant charge. Verify model compatibility before ordering using your refrigerator's serial number and parts list.
