Abstract
A method of controlling a refrigerator includes detecting opening/closing of an ice dispensing duct, through which ice is taken out, and storing an opening time of the ice dispensing duct per time interval. Each time interval is classified as a use time when the opening time of the ice dispensing duct is equal to or greater than a reference time and each time interval is classified as a non-use time when the opening time of the ice dispensing duct is less than the reference time.
