Safe first steps
- Check if the fridge and freezer doors are fully closed.
- Inspect the door seals for any damage or debris that may prevent proper sealing.
- Ensure that the fridge is not overloaded, which can obstruct airflow.
- If the temperature remains high after checking the doors and seals, adjust the temperature settings to a lower value.
- 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.
