Abstract: The ice maker for refrigerator and driving method thereof disclosed herein have advantages over a full ice level detection method using mechanical device in that an ice height can be more accurately detected by a detection signal reflected from ice, wherein an ultrasonic signal is transmitted to the ice to sense the height of ice in the ice storage bin using the reflected ultrasonic signal, enabling to precisely detect the ice height, prevent the overflow of ice, prolong the life and prevent the failure of the ice maker for refrigerator.
