Safe first steps

  1. Check the temperature setting of the freezer to ensure it is set to -18 °C or lower.
  2. Inspect the freezer for any visible ice buildup or blockages that may affect airflow.
  3. If ice buildup is present, defrost the freezer according to the manufacturer's instructions.
  4. If the issue persists after checking the temperature and defrosting, arrange a service visit — do not use the appliance.

When to stop

  • Stop if you notice unusual noises or the freezer is not cooling properly — risk of component damage.
