Possible Causes

Failed display backlight LEDs, Loose connector between UI and main board, Partial failure of UI PCB, Low voltage from main board to UI

How to Fix / Troubleshooting

Safety: Unplug the wine cooler before removing the control panel.

Steps:

  • Check for faint display: Shine a flashlight at an angle; if you can see numbers faintly, the backlight has failed.
  • Inspect connections: Remove the control panel and verify that the ribbon cable and connectors between the UI and main board are secure.
  • Replace UI PCB: If connections are good and the display remains blank or dim, replace the Fagor user interface/display board.
  • Main board: If a new UI does not restore the display, the main PCB may not be supplying correct voltage and should be replaced.
