This capacitor stores and releases electrical energy to support the appliance's circuit during startup and operation. Replacing a weakened capacitor can restore reliable performance and reduce humming, hard starting, or stalling in the affected component.
- Provides a power boost at startup and helps stabilize voltage during operation
- Helps the connected component start promptly and operate smoothly under load
- Common failure signs include humming, slow or no start, or intermittent operation
- Contribute to overheating or a tripped breaker/fuse when the component tries to start
What's included: One capacitor. Install notes:
- Disconnect power at the breaker or unplug the appliance. Before handling, safely discharge the old capacitor using a proper resistor-rated tool.
- Photograph or note wire positions; move each lead to the same-labeled terminal on the new capacitor and ensure snug connections.
- Mount the capacitor securely in its bracket; keep terminals covered and clear of metal surfaces.

Loud clicking from the back of my refrigerator Randy W. • Granbury , TX • March 04, 2015
Research question lead to others that had the same issue. Consensus lead to a common repair. Compressor overload switch going bad. After ordering the correct parts, I changed out both the switch and the motor start capacitor just in case. After cleaning the equipment, I then put everything back together. Results were, clicking gone, seems to be quieter operation because of cleaning, more efficient cooling and nerves calmed.
