The General Electric WR08X21100 Refrigerator Overload & Start Relay helps ensure reliable compressor startup and protects against electrical overload. This component is designed for compatible refrigerators to regulate power to the compressor during the start cycle. It works by briefly boosting the electrical current needed to start the compressor, then switching off once normal operation begins, while the overload function cuts power if excessive heat or current is detected. This helps prevent damage to the compressor and other internal parts. Replacing a faulty relay can restore proper cooling performance, reduce strain on the system, and support consistent, efficient refrigerator operation.
