  3. If the temperature is still incorrect, unplug the fridge for 5 minutes and then plug it back in.
  4. If the error persists after resetting, arrange for a professional service visit to check the fridge compartment sensor.

When to stop

  • Stop if the fridge compartment temperature does not stabilize after the reset — risk of food spoilage.
