Ice maker and refrigerator including the same

A control method of a refrigerator, the refrigerator comprising an ice tray receiving water to generate ices, a motor capable of being rotated in a forward or reverse direction, an ejector rotating the ices made in the ice tray to discharge the ices from the ice tray, the ejector rotated by the motor, a heater selectively supplying heat to the ice tray, and an ice making compartment fan supplying the cool air to the ice tray, comprising:

• a first step of sensing whether the ejector reaches a first setup position while being rotated;
• 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,
• wherein the ejector continues to be rotated while the second to fourth steps are implemented.
