How to Fix / Troubleshooting
Safety: Unplug before removing the control panel.
Steps:
- Check for response: Press buttons to see if the unit responds (fan/compressor sounds). If it does, the issue is likely limited to the display.
- Inspect connections: Remove the front/top panel to access the display control board. Reseat any ribbon cables or connectors between the display and main board.
- Look for damage: Check for cracks, burn marks, or corrosion on the display board, especially if water has dripped onto the panel.
- Replace display board: If reseating cables does not restore the display, replace the display control board assembly.
