Main Power Control Board Assembly
The Main PCB contains the SMPS (Switched-Mode Power Supply) which is responsible for converting high-voltage AC into regulated low-voltage DC. A failure in the oscillation transformer or the voltage regulator on this board causes a total loss of logic power to the refrigerator. This results in a 'dead' symptom where the display, lights, and compressor fail to initialize.

Noise Filter Assembly
This component is the primary entry point for AC power and contains an integrated high-current fuse. If a power surge or internal component short occurs, the fuse will blow to prevent a fire hazard, effectively severing the electrical connection to the rest of the appliance. Replacing the assembly is necessary because the fuse is typically soldered or integrated into the housing for safety compliance.

Display Control PCB
While less likely to cause a total lack of cooling, a failure in the communication bridge of the display PCB can lead to a 'dead' user interface. If the main board is functioning but the UI is unresponsive, it may give the appearance of a total power failure to the user.
