4.3 Manual Defrost System
This refrigerator uses a manual defrost system. Frost buildup in the freezer compartment is normal and should be defrosted periodically to maintain efficiency.
- Defrost when frost accumulation reaches about 1/4 inch (0.6 cm) thick.
- Turn off the refrigerator and unplug it from the power outlet.
- Remove all food items and place them in a cooler.
- Leave the freezer door open to allow frost to melt naturally. Do not use sharp objects or heating devices to speed up defrosting.
- Wipe away melted water with a clean cloth.
- Once defrosted and dry, plug the refrigerator back in and allow it to cool before returning food.
