How to Fix / Troubleshooting
Safety: Unplug the freezer before accessing the compressor or control board.
Steps:
- 1. Check control settings: Ensure the freezer is not in demo mode and that the temperature is set correctly.
- 2. Listen for relay click: If no click is heard from the control when cooling should start, suspect the control module.
- 3. Inspect compressor area: Remove the rear panel and check wiring to the compressor and start device. Repair any loose or burnt connections.
- 4. Replace start device: If the start relay/PTC is suspect, replace it with a Neff-compatible part.
- 5. Control module replacement: If the compressor never receives power despite correct wiring and start device, replace the main control module.
