Possible Causes
Loose ribbon cable between UI and main control, Moisture in control panel, Failed user interface board, Defective main control board
How to Fix / Troubleshooting
Safety: Unplug the freezer before opening the control console.
Procedure:
- Access the control console: Remove screws securing the front/top control panel and gently lower it.
- Inspect ribbon cable: Check the flat cable between the user interface (buttons/display) and the main control board. Reseat both ends firmly.
- Look for moisture or corrosion: If there are signs of condensation or liquid intrusion, dry the area thoroughly and clean corrosion with electronic contact cleaner.
- Check for physical damage: Cracked boards or burnt components on the UI or main control indicate replacement is needed.
- Replace faulty board: If reseating cables does not clear E9, replace the user interface board first. If the issue persists, replace the main control board.
Tip: Avoid using excessive water or cleaners near the control panel to prevent future moisture damage.
