Main Power Control Board (PCB)
The main PCB manages the distribution of power to all sub-systems via a Switch Mode Power Supply (SMPS) circuit. Failure of the transformer or voltage regulator on this board prevents the creation of the 5V and 12V DC rails required for the microprocessor and display to boot. This results in a completely non-responsive appliance with no signs of life.

Noise Filter Assembly
The noise filter is the primary interface between the wall outlet and the internal wiring, containing induction coils and a ceramic fuse. If a voltage spike occurs, the internal fuse clears to protect the control boards from thermal damage. Once this fuse is blown, the circuit is physically opened, resulting in zero current flow to the rest of the refrigerator.

User Interface (UI) Display PCB
The UI board provides the visual feedback for the appliance's power state. If the board's internal logic fails or a short circuit occurs on the communication bus, the display will remain dark even if the main PCB is sending power. In some failure modes, a shorted UI board can pull down the logic rail of the main board, causing a 'dead' appearance across the entire system.
