Freezer fan not running, uneven temperatures, possible F06 fan error on display

Safety first: Unplug the refrigerator before removing freezer panels.

Steps:

• 1. Confirm symptom: Food near the evaporator cover may be frozen solid while other areas are soft. Little airflow is felt when the door switch is held closed.
• 2. Remove drawers and back panel: Take out freezer baskets and unscrew the rear inner panel to access the evaporator and fan.
• 3. Check for frost/ice: If the fan area is heavily iced, defrost the unit completely. This may indicate an underlying defrost problem (see defrost-related faults).
• 4. Inspect fan motor: Look for signs of water ingress, rust, or burnt smell. Ensure the fan blades are intact and not rubbing.
• 5. Electrical check (optional): With the unit unplugged, disconnect the fan and measure motor resistance. An open circuit indicates a failed motor.
• 6. Replace fan motor: Install a genuine V-ZUG freezer evaporator fan motor, reconnect the harness, and reassemble the panel ensuring no wires are trapped.
• 7. If F06 remains: The main control board may not be driving the fan. Professional diagnosis is recommended.

Warning: Metal edges inside the freezer can be sharp; wear cut-resistant gloves.
