Possible Causes
Door left open or frequently opened, Power outage or recent warm loading, Failed evaporator fan, Dirty condenser coil, Refrigerant leak or weak compressor
How to Fix / Troubleshooting
Safety: Basic checks can be done with power on; unplug before removing panels.
- Verify door closure: Ensure the door closes fully and the gasket seals all around. Correct any obstructions.
- Allow recovery time: If you recently loaded warm bottles or had a power outage, allow 24 hours for temperature to stabilize.
- Check airflow: Listen for the evaporator fan running when the compressor is on. If silent, inspect and replace the fan as needed.
- Clean condenser: Remove the grille and vacuum the condenser coil to improve cooling efficiency.
- If temperature does not drop: After cleaning and verifying fans, persistent high temperature may indicate a sealed system issue requiring a Wolf-authorized technician.
