Compressor Start Relay and Overload Assembly
The clicking sound is the physical actuation of the bimetallic overload protector. This occurs when the PTC thermistor fails to energize the start windings of the compressor, leaving the motor in a locked-rotor state that draws high current. The overload protector opens the circuit to prevent the compressor from overheating, then resets as it cools, creating a repeating cycle.

Compressor Run Capacitor
The run capacitor provides the necessary phase-shifted current to maintain the magnetic field required for the compressor motor to achieve sufficient torque. If the capacitor has suffered a dielectric breakdown or lost its capacitance, the compressor may struggle to turn over, resulting in a stall that triggers the overload protector click.

Main Power Control Board
While less likely given the specific 'clicking' symptom usually associated with the compressor, a failed relay on the main control board can chatter or fail to provide stable voltage to the cooling circuit. This intermittent power delivery can cause the compressor's protective components to actuate as they see unstable current loads.
