Inverter Power Control Board
The clicking sound is the audible manifestation of the board's protection relay or the compressor's thermal overload protector cycling after a failed startup attempt. This board is responsible for converting AC to DC and providing three-phase pulse-width modulation to the compressor; if the IPM (Intelligent Power Module) on the board fails, it cannot generate the torque needed to spin the motor, resulting in the reported clicking and no cooling.

Main Power Control Board
The main board manages the communication signal sent to the inverter board; if the logic circuit responsible for the 'compressor run' command fails or sends an intermittent signal, it can cause the inverter to cycle rapidly. This results in repeated relay clicking as the system fails to maintain a stable refrigeration cycle.

Digital Inverter Compressor
Internal mechanical seizure, known as a locked rotor, causes the motor to draw excessive current upon startup. This high amperage trip is detected by the inverter board or a physical overload protector, which cuts power to prevent a thermal event, creating the clicking sound as the protection circuit resets.
