F4 · Freezer temperature sensor failure

Safe first steps

1. Unplug the fridge freezer from the power outlet to ensure safety while inspecting.
2. Check the temperature settings to ensure they are correctly set for the freezer.
3. Inspect the freezer for any visible ice buildup that may affect the sensor's function.
4. If ice buildup is present, defrost the freezer completely and then plug it back in to see if the error clears.
5. If the error persists after defrosting, the temperature sensor likely needs replacement — arrange a service visit.

When to stop

• Stop if you notice any unusual smells or sounds coming from the appliance — risk of fire.
