Abstract: A method controls a refrigerator including first and second trays defining an ice chamber, a driving unit for moving the second tray, an ice bin for storing ice produced in the ice chamber, and an ice-fullness detection means for detecting whether or not the ice bin is full of ice. The method includes supplying water to the ice chamber when the second tray is at a water-supply position, making ice after the second tray has moved to an ice-making position in an inverse direction after the water supply has been completed, determining whether the ice bin is full of ice after the ice making is completed, moving the second tray to an ice-separating position and then rotating in the inverse direction if it is not determined whether or not the ice bin is full of ice, and determining again whether the ice bin is full of ice after ice separation is completed.

Abstract: An ice maker of a refrigerator includes an upper assembly having an upper tray that defines upper portions of a plurality of ice making chambers as well as a lower assembly located vertically below the upper assembly that is configured to rotate relative to the upper assembly. The lower assembly includes a lower tray that defines lower portions of the plurality of ice making chambers. Each of the plurality of ice making chambers is configured to receive water when the lower assembly rotates relative to the upper assembly and generate an ice piece within when the upper and lower portions of the ice making chambers are joined. The lower tray includes a deformable portion that is configured to, based on an outward expansion of the ice piece within the ice making chamber during ice generation, change from a first shape to a second shape.
