Dual Run Capacitor
The dual run capacitor provides the essential electrical phase shift required to generate starting torque in the compressor motor. When the capacitor's dielectric strength fails, the compressor cannot initiate rotation and instead enters a 'stalled' state, producing a loud electromagnetic hum as the windings are energized without mechanical movement. Because the compressor is not rotating, refrigerant is not circulated, leaving the indoor air warm while the outdoor unit remains loud.
