Dual Run Capacitor
The capacitor provides the essential electrolytic 'kick' (starting torque) required to initiate the rotation of the compressor and fan motors. Over time, heat causes the internal dielectric film to degrade, leading to a loss of microfarad (µF) capacitance. Without this phase-shifted current, the motors will stall and fail to start, often resulting in an audible hum or complete silence.
