Dual Run Capacitor
The capacitor stores energy to provide the necessary electrical phase shift to start the compressor and fan motors. When the dielectric material inside fails, the motor cannot overcome static inertia, resulting in a 60Hz magnetic hum from the windings while the rotor remains stationary. Replacing this component restores the starting torque required for the cooling cycle to begin.

Definite Purpose Contactor
The contactor acts as the heavy-duty relay that sends high-voltage power to the unit. If the copper contacts are pitted, charred, or if the solenoid coil is partially shorted, it will produce a loud humming or buzzing sound while failing to pass sufficient current to start the compressor. This component is the primary physical bridge between the thermostat's call for cooling and the unit's power supply.

Hard Start Kit (Relay & Start Capacitor)
As compressors age, internal friction (stiction) or high head pressure can make it difficult for a standard run capacitor to initiate rotation. A hard start kit provides a significant boost of torque for a fraction of a second to break the rotor free. This is the standard engineering solution for a 'stuck' compressor that is humming but failing to cycle.
