Possible Causes
Failed display PCB, Loose connector between display and main board, Blown low-voltage fuse on PCB, Damaged display backlight
How to Fix / Troubleshooting
Safety: Disconnect mains power before accessing the control area.
- Check if unit cools: Listen for compressor and fan operation. If cooling continues, the issue is likely limited to the display/UI.
- Inspect connectors: Remove the control panel and verify all plugs between the display board and main PCB are secure.
- Check for fuses: Some boards have small fuses protecting the display circuit. Test and replace with identical ratings if blown.
- Replace display board: If wiring and fuses are good, install a new Grundig display / UI board.
