Possible Causes
Loose or damaged wiring harness between boards, Failed display/user interface board, Failed main control board, Corroded connectors at top hinge or rear
How to Fix / Troubleshooting
Safety first: Disconnect power before removing control covers or handling wiring.
- Power reset: Unplug the refrigerator for 5 minutes, then restore power. Sometimes CF clears after a hard reset.
- Inspect harness connections: Remove the control panel cover (usually at the top of the fresh food compartment or on the door) and verify all ribbon cables and harness plugs are fully seated.
- Check hinge wiring: On French-door models, inspect the wiring bundle at the top door hinge for pinched or broken wires, especially if the door has been removed previously.
- Board diagnosis: If wiring is intact, either the main control board or the user interface board is not communicating. Visual inspection for burnt components or corrosion can help, but board-level diagnosis is advanced; replacement of one or both boards is typically required.
