Inverter Power Control Board
The clicking sound is the electromechanical relay or thermal overload protector on the inverter board cycling as it fails to start the compressor. This component is responsible for converting AC power into the variable frequency 3-phase DC signal required by the compressor; when the board's internal power module fails, it enters a repetitive restart loop. Replacing the board restores the necessary current to break the compressor's static friction and resume the refrigeration cycle.

Main Power Control Board
The main PCB sends a low-voltage pulse-width modulation (PWM) signal to the inverter board to dictate compressor speed. If the communication relay on this board is faulty or high-impedance, it may send intermittent signals that cause the inverter to 'click' as it struggles to interpret the start command. This is less common than inverter failure but is the secondary cause of drive-train communication errors.

Digital Inverter Compressor
An internal mechanical seizure, known as a locked rotor, prevents the compressor from turning despite receiving the correct electrical signal. This state creates excessive back-electromotive force, tripping the inverter's safety circuit and causing a clicking sound as the system attempts to retry the start sequence. This represents a terminal failure of the sealed system's mechanical core.
