Abstract
Disclosed is an operation control system for a refrigerator which can prevent extreme change of the internal temperature by an extra method when abnormality occurs in its cooling state. This system judges whether the temperature change is abnormal or not, stops an operation control method based on temperature when the change is abnormal, and controls the operation of the refrigerator by another operation control method based on time in which the stop and the restart are repeated at predetermined intervals respectively.
