Possible Causes
Loose connector to display PCB, Failed display/control board, Faulty low-voltage output from main control board
How to Fix / Troubleshooting
Safety: Unplug the unit before accessing control boards.
Steps:
- Check if cooling works: Listen for compressor and fans. If the unit cools normally, the problem is likely limited to the display/control board.
- Access display board: Remove the front control panel trim and inspect the display PCB and wiring.
- Reseat connectors: Unplug and reconnect the harness between the main board and display board.
- Inspect for damage: Look for burnt components or cracked solder joints on the display PCB.
- Measure low-voltage (technician level): A professional can verify that the main board is supplying the correct DC voltage to the display. If not, the main board is faulty.
- Replace faulty board: Replace the display/control board if only the display is dead; replace the main control board if it is not providing power to the display.
