Defrosting

The cooling fins of the refrigerator operate at below freezing temperature and will naturally form frost from humidity, which is always
present in the air. The humidity inside the refrigerator increases:
- With higher outside temperature and humidity.
- With the storage of non-sealed fresh foods or warm foods.
- With the amount of time that the door(s) are open.
- With any air leakage into the refrigerator.
Although the refrigerator is not frost -free, it is made to limit frost on the cooling fins. At regular intervals, the temperature control system
automatically melts most of the frost from the cooling fins. The water from the cooling fins drains into a collection cup that is attached to
the back of the refrigerator. The heat of the cooling system evaporates the water from the collection cup.
It is normal for frost to collect inside the freezer. Excess frost decreases the cooling performance of the refrigerator. Defrost the
refrigerator and freezer as necessary:
- Remove all food from the refrigerator.
- Turn the refrigerator OFF.
