E7 error displayed; freezer may not cool properly and fan operation may be erratic or stopped.

Safety first: Unplug the freezer before accessing the fan. Beware of sharp metal edges and ice.

Access the evaporator fan:

• Remove drawers and the rear interior panel to expose the evaporator and fan shroud.
• The fan is typically mounted above or in front of the evaporator coil.

Check for obstructions:

• Inspect for heavy ice buildup around the fan blades or shroud.
• Spin the fan blade gently by hand; it should rotate freely without scraping.

Electrical checks:

• Disconnect the fan connector.
• Measure resistance across the fan motor terminals; an open circuit indicates a failed motor.
• Inspect the wiring harness from the fan to the main PCB for damage or loose connections.

Corrective actions:

• Manual defrost: If ice is blocking the fan, fully defrost the freezer (doors open, towels in place) until all ice is gone. Do not chip ice with sharp tools.
• Replace fan motor: If the motor is open or noisy/grinding when spun, install a new Blomberg-compatible evaporator fan motor. Transfer the fan blade if it is separate and undamaged.
• Repair wiring: Replace any damaged wires or connectors using proper crimp terminals.

Test: Reassemble the rear panel, restore power, and listen for the fan starting once the compressor has run for a few minutes. Confirm that E7 does not return and that airflow is strong.
