Fridge freezerCaution — Know When to StopFixLens verified

Safe first steps

  1. Check if the fridge and freezer doors are fully closed.
  2. Inspect the door seals for any damage or debris that may prevent proper sealing.
  3. Ensure that the fridge is not overloaded, which can obstruct airflow.
  4. If the temperature remains high after checking the doors and seals, adjust the temperature settings to a lower value.
  5. If the F1 error persists despite these checks, arrange a service visit — do not use the appliance.

When to stop

  • Stop if you notice any unusual noises or if the appliance is excessively warm to the touch — risk of component damage.
