Abstract
A refrigerator includes an ice tray, a motor, an ejector including a rotary shaft and a protrusion pin, and a heater for selectively supplying heat to the ice tray. A control method of the refrigerator includes a first step of sensing whether the ejector is rotated to reach a first setup position; a second step of driving the heater and stopping driving of an ice making compartment fan if the first step is satisfied; a third step of determining whether the ejector is rotated to reach a second setup position; and a fourth step of stopping driving of the heater if the third step is satisfied, and wherein the ejector continues to be rotated while the second to fourth steps are implemented.
