Main Control Board
The main PCB contains the AC-to-DC rectification circuit that powers the refrigerator's logic. A failure in the switch-mode power supply section of this board prevents the microprocessor from initializing, resulting in a total loss of user interface response and component activation. Replacing the board restores the necessary DC voltage rails for the unit's operating system.

Electronic Control Board
This secondary control board governs specific load distributions. In some production runs of the WRF series, a short circuit in the DC bus of this board can pull down the entire system voltage, mimicking a total power loss. It is the primary alternative failure point for power-related issues that originate within the logic-level circuitry.

User Interface Control Board
While less common for a 'no cooling' symptom, a shorted UI board can interrupt the communication bus (LIN/CAN) of the refrigerator. If the UI board fails in a manner that grounds the 5V logic rail, the main board may enter a protective shutdown mode, making the entire appliance appear electrically dead.
