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.

Abstract: A refrigerator includes a first tray assembly to define one portion of an ice making cell, a second tray assembly to define another portion of the ice making cell, a heater disposed adjacent to at least one of the first or second tray assemblies, and a controller configured to control the heater. The refrigerator further includes a pusher including a first edge having a surface pressing the ice or at least one of the first and second tray assemblies to easily separate the ice from the tray assemblies, a bar extending from the first edge, and a second edge disposed at the end of the bar; and a pusher link having a connection part connected to the pusher. The controller controls at least one of the pusher or the second tray assembly to move and to change a relative position between the pusher and the second tray assembly.
