Possible Causes
Blown low-voltage fuse on control board, Failed display module, Loose harness connection to UI board
How to Fix / Troubleshooting
Safety: Unplug the freezer before accessing the control board or display.
Steps:
- Verify cooling: Listen for compressor and fans. If they run, the main control may still be working and only the display is out.
- Access control area: Remove the control panel or rear control box cover.
- Check fuses: Look for small fuses on the control board. Test with a meter and replace with the same type and rating if blown.
- Inspect connectors: Ensure the harness to the display/UI board is fully seated.
- Replace display/UI board: If fuses and wiring are good but the display remains blank, replace the user interface/display module.
