The run capacitor stores and delivers the precise electrical charge needed to start and sustain the condenser fan motor or compressor. When this capacitor degrades or fails, you'll typically notice symptoms such as the unit humming without starting, the motor running sluggishly or overheating, or the system shutting down shortly after startup. Replacing it with the correct OEM part ensures factory-matched performance and protects your motor investment.
