Safety first: Disconnect mains power before removing the control panel or top cover.

Check power at outlet: Plug another appliance into the same outlet to confirm power supply.
Inspect control panel: Look for signs of moisture, cracks, or burnt smell around the display and buttons.
Reset electronics: Unplug the fridge for 10–15 minutes, then plug back in. Some transient faults clear with a reset.
Access UI board: On many models, the UI is in the door or top front. Remove the trim and screws to access the board. Check that all connectors are firmly seated.
Dry moisture: If condensation is present, gently dry the area with a soft cloth and allow several hours before reassembly.
Replace UI board if dead: If there is no display or response after reset and connections are secure, the user interface board likely needs replacement.
Further checks: If a new UI does not restore function, the main control board or wiring harness may be faulty and should be tested by a technician.
