Dual Run Capacitor
The dual run capacitor is responsible for creating the electrical phase shift necessary to initiate rotation in the compressor and fan motors. When the capacitor fails, the motors cannot overcome inertia or refrigerant head pressure, leading to an 'inductive hum' while the components remain stationary. Replacing this component restores the starting torque and protects the motor windings from thermal damage.
