Freezer is cold at the bottom but warm at the top; upper shelves are soft while lower drawers are frozen.
Safety Warning
This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.
If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the freezer before removing interior panels.
Check for airflow blockage:
- Ensure large packages are not blocking air vents at the back or top of the freezer.
- Rearrange contents to allow free air circulation.
Inspect evaporator fan:
- Remove drawers and the rear interior panel to access the evaporator and fan.
- Check for ice buildup around the fan and air channels. If present, fully defrost the unit by turning it off and leaving doors open until all ice melts.
- Spin the fan blade by hand; it should move freely.
Electrical test:
- Disconnect the fan and measure motor resistance. An open circuit indicates a failed motor.
Corrective actions:
- Defrost and clean: Remove all ice and ensure drain channels are clear to prevent re-freezing.
- Replace fan motor: If the motor is open or noisy, install a new Blomberg-compatible evaporator fan motor.
Test: Reassemble, restore power, and verify that air can be felt moving at the top vents after the compressor has run for several minutes.
