Refrigerator dead: no lights, no display, nothing running
Work from the outlet inward: supply, cord, door/display harness, then the boards. Many 'dead display' calls on French-door and side-by-side units are harness faults at the door hinge, not failed boards.
Before you start
- Checking voltage at the outlet and the board is a live test: insulated probes, one hand, no jewelry.
- Unplug the unit before you disconnect harnesses or remove boards; let inverter boards discharge.
