How to Fix / Troubleshooting
Safety warning: Unplug the cooler before accessing the display area.
- Check interior light and cooling: If cooling and lights work, the issue is likely isolated to the display circuit.
- Access display PCB: Remove the control panel trim and expose the display board.
- Inspect connectors: Ensure the harness from the main control board to the display is firmly connected at both ends.
- Replace display board: If connections are good but the display remains blank or unreadable, replace the "Phiestina display PCB".
- Control board check: If a new display does not light, the "Main control board" may not be supplying proper voltage and may need replacement.
