How to Fix / Troubleshooting
Safety: Unplug the unit before accessing the compressor area.
Steps:
- Check for vibration: Lightly touch the compressor shell when the unit should be cooling. No vibration or warmth suggests it is not running.
- Inspect start device: Remove the compressor terminal cover and check the start relay and overload for burn marks or loose fit.
- Replace start device: If the relay rattles when shaken or shows damage, replace it with the correct Neff part.
- Test again: Restore power and observe if the compressor starts and cooling resumes.
If the compressor still does not start or trips repeatedly, a professional sealed‑system diagnosis is required.
