Abstract
A refrigerator is defrosted by comparing a sensed temperature in the refrigerator with a predetermined temperature when a defrost start time is reached. If the sensed temperature is too high, a compressor is caused to operate in order to reduce the temperature to the predetermined temperature. Then, the open/closed conditions of the refrigerator doors are sensed, and the defrost heater is activated if the doors are sensed as being closed.
