How to Fix / Troubleshooting
Safety: Unplug the refrigerator before accessing the main control board.
- Power reset: Disconnect power for at least 10 minutes to allow capacitors to discharge, then reconnect and observe if E16 returns.
- Check supply voltage: Ensure the outlet provides stable voltage within the specified range. Avoid using undersized extension cords.
- Inspect main board: Remove the rear electronics cover and visually inspect the Cecotec main control board for burnt components or swollen capacitors.
- Reseat connectors: Firmly reconnect all harnesses, especially those from temperature sensors.
- Replace main board: If E16 persists and sensors are known good, replace the main control board with the exact Cecotec part number. This is best done by a qualified technician.
