ABSTRACT:
Disclosed is a method of controlling an operation for determining an optimum ice removing period based on the present temperature in a freezing compartment and the present temperature in an ice making compartment in an automatic ice maker of a refrigerator. A controlling section measures a first present temperature of an ice tray through an ice making sensor installed at a portion of the ice tray and compares the first present temperature with a first reference temperature. If the first present temperature is the same as or higher than the first reference temperature, the controlling section compares an accumulated value of time computed based on a weight value established according to a range of the present temperature of the freezing compartment with a reference time. If the accumulated value is the same as or larger than the reference time, the controlling section compares a second present temperature of the ice tray, measured through the ice making sensor, with a second reference temperature and carries out an ice removing operation. Therefore, the efficiency of the ice making can be maximized through a reduction in the ice making time. Further, the electric power consumed by the ice maker or the refrigerator can be reduced.
