Main Power Control Board Assembly
The Main PCB contains the Switched-Mode Power Supply (SMPS) responsible for generating DC logic voltage. Forensic evidence suggests that thermal fatigue or voltage transients often cause the primary switching transistor or the flyback transformer to fail, resulting in a total loss of power to the refrigerator's control systems and user interface.

Noise Filter Assembly
This component serves as the entry point for AC power and filters electromagnetic interference. It contains an internal non-serviceable fuse designed to sacrificialy fail during a high-voltage surge; if this circuit opens, the entire appliance loses the electrical path to the main controller.

User Interface Display PCB
While less likely to cause a 'total' dead state, a localized short-circuit on the communication bus within the door's display board can occasionally pull down the 12V DC rail of the main board, causing the refrigerator to appear unresponsive even if the main board is receiving power.
