How to Fix / Troubleshooting

Safety: Sealed system diagnosis and repair require specialized tools and certification.

User checks:

Clean condenser: Pull the unit out and thoroughly clean the condenser coils and ventilation grills.
Check door seal: Ensure the door gasket seals tightly all around. Replace if cracked or deformed.
Reduce load: Avoid overloading the cabinet and allow space for air circulation between bottles.
Monitor frost pattern: If you can see the evaporator, a small patch of frost only near the inlet and the rest warm suggests a refrigerant or blockage issue.
Call a technician: If basic cleaning and sealing do not restore proper cooling, contact a Neff-authorized technician for leak detection and sealed system repair.
