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: The present invention relates to a refrigerator. A refrigerator of the present invention may comprise: a first tray assembly forming a part of ice-making cells; a second tray assembly forming the other part of the ice-making cells; and a heater. In order to reduce the transfer heat, which is transferred from the heater to any one of the first and second tray assemblies, to ice-making cells formed by the other tray assembly, the one tray assembly may comprise a first part forming at least a part of the ice-making cells. The degree of heat transfer of the first part may vary along the outer circumferential surfaces of the ice-making cells.
