Refrigerant Step Valve Assembly
The step valve uses a stepper motor to oscillate a cam that directs refrigerant flow to either the fridge or freezer evaporators. A clicking sound indicates the internal motor is unable to rotate the valve plate, usually due to mechanical binding or internal gear stripping. This prevents the heat exchange cycle from reaching the evaporators, leading to a total loss of cooling.

Main Power Control Board
The main PCB contains relays that switch power to the compressor and fans; a 'clicking' sound often originates from these relays rapidly cycling on and off. If the board's micro-controller detects an implausible resistance from a sensor or a voltage irregularity, it may cycle the compressor relay without successfully starting the cooling loop.

Inverter Power Control Board
This board translates signals from the main PCB into 3-phase power for the compressor. If the inverter fails, it can produce an audible click as it attempts to initialize the compressor's permanent magnet motor, failing to overcome the starting torque and resulting in a 'no cooling' state.
