Dual Run Capacitor
The dual run capacitor is responsible for providing the phase-shifted voltage to the compressor's start winding. If the dielectric material within the capacitor fails, the compressor cannot overcome its static inertia (locked rotor), while the fan (on a separate capacitor tap) may continue to spin. This is the primary failure mode for the GSX16 series when the unit hums but does not engage the refrigeration cycle.

Hard Start Kit
As compressor bearings age or if the system experiences high head pressure during startup, the standard run capacitor may provide insufficient torque. A hard start kit utilizes a potential relay and a dedicated start capacitor to provide a high-torque boost, overcoming mechanical stiction or high-pressure differentials that the standard capacitor cannot resolve.

AC Contactor
Although the fan is running, a two-pole contactor can suffer from localized carbon tracking or pitting on only one set of contacts. If the contacts feeding the compressor's 'Common' or 'Run' terminals are fouled, the fan will receive power while the compressor remains electrically isolated, preventing the motor from energizing.
