Inverter Power Control Board
This board translates logic signals from the main PCB into 3-phase DC power for the compressor. On this model, high-voltage spikes or component fatigue frequently cause the inverter to fail, resulting in a compressor that never starts despite the rest of the fridge appearing functional.

Fridge Evaporator Cover Assembly
This is a known pattern failure where moisture accumulates and freezes on the evaporator, eventually encasing the fan in ice. This stops air circulation to the fresh food compartment, meaning the compressor runs but cold air is never moved into the cabin.

Main Control Board
The main PCB manages the defrost cycles and the 3-way refrigerant valve. A stuck relay or logic error on this board can prevent the system from switching from 'defrost' back to 'cool' or prevent the valve from directing refrigerant to the evaporator coils.
