Freezer displays F7 and alarm sounds; temperature may be too high despite compressor running

Safety first: Unplug the appliance before cleaning coils or accessing the compressor area.

Steps:

• 1. Check installation: Ensure the freezer has the ventilation clearances specified by Miele (top, sides, and rear). Remove any items blocking air grills.
• 2. Clean condenser: Access the rear or front kick panel (depending on model) and locate the condenser coil. Use a soft brush and vacuum to remove dust and lint. Do not bend the fins.
• 3. Verify condenser fan operation: On models with a condenser fan, observe if it runs when the compressor is on. If not, test the fan motor and replace if defective.
• 4. Ambient temperature: Confirm the room temperature is within Miele's specified operating range. Extremely hot rooms can trigger overheat faults.
• 5. Reset and monitor: After cleaning and ensuring proper airflow, reconnect power and monitor operation. If F7 returns, the condenser temperature sensor or control board may be faulty and require professional diagnosis.
