Dual Run Capacitor
The capacitor stores energy to provide a phase-shifted current to the compressor's start winding. Without this specific electrical lag, the motor cannot generate the magnetic torque required to initiate rotation against high refrigerant head pressure. The fan continues to run because it uses a separate, lower-capacitance terminal on the same device that often remains functional longer than the high-capacitance compressor side.

AC Contactor
The contactor acts as the heavy-duty relay that switches 240V power to the compressor and fan. Over time, the silver-plated contacts can become pitted or carbon-fouled, creating high resistance. This can result in a voltage drop significant enough to prevent the compressor from starting while still providing enough current to drive the lower-amperage fan motor.

Hard Start Kit
As compressors age, internal mechanical friction and bearing wear increase the 'break-away' torque required to start. A hard start kit utilizes a potential relay and a dedicated start capacitor to provide a massive, momentary increase in starting torque, allowing the compressor to overcome mechanical binding that a standard run capacitor can no longer handle.
