How to Fix / Troubleshooting

Safety first: Unplug the refrigerator before removing the control panel or display housing.

Steps:

  • 1. Clean the panel: Wipe the touch surface with a soft, dry cloth to remove moisture or residue that may affect sensitivity.
  • 2. Power reset: Unplug the unit for 5 minutes, then reconnect and test the panel.
  • 3. Access the UI board: Carefully remove the trim and screws holding the display. Check the ribbon cable and connectors for secure fit and corrosion.
  • 4. Inspect for damage: Look for signs of water ingress or burnt components on the UI PCB. If present, replace the display/control panel assembly.
  • 5. If UI is good but still unresponsive: The main PCB may not be communicating with the UI and may require replacement.
