Moisture can form frost inside the refrigerator or on the evaporator. This will reduce
refrigeration capacity. Please defrost the refrigerator to avoid such situations.
• Do not use hard or sharp tools to remove ice or loosen frozen items.
• Do not use mechanical devices or other methods not recommended by the
manufacturer to speed up the defrosting process.
1. Take out all items from the refrigerator.
2. Chill them in another refrigerator if necessary.
3. Turn off the refrigerator.
