Dual Run Capacitor
The capacitor provides the essential phase-shift required to create a rotating magnetic field in the compressor and fan motors. When the capacitor fails, the motors cannot generate starting torque, leading to a stalled state where the windings hum or buzz as they attempt to move. This is the most common failure point in HVAC condensing units due to thermal stress and voltage fluctuations.

AC Contactor
The contactor is an electromechanical switch that closes the 240V circuit to the unit. If the magnetic coil is weak or the contacts are pitted/corroded, the relay may vibrate (buzz) instead of making a solid connection. This prevents the high-amperage current from reaching the compressor and fan effectively.

Hard Start Kit
If the capacitor is functional but the compressor is experiencing high internal friction or high head pressure during startup, it may fail to turn over. This kit adds a temporary start capacitor and a potential relay to provide a massive increase in starting torque to break the rotor free from a locked state.
