An ice maker of a refrigerator includes a tray assembly having an upper tray that defines upper portions of a plurality of ice making chambers. Each of the plurality of ice making chambers is configured to receive water and generate an ice piece. The tray assembly also includes a lower tray that is located vertically below the upper tray, that is configured to rotate relative to the upper tray, and that defines lower portions of the plurality of ice making chambers, wherein at least one of the upper tray or the lower tray comprises a flexible tray made of a flexible material. Additionally, a case is configured to accommodate the flexible tray to restrict a deformation of the flexible tray. A heater that is located between the case and the flexible tray is configured to supply heat to the plurality of ice making chambers through the flexible tray.

A refrigerator includes a cabinet, an ice maker configured to make spherical ice, and an ice bin for storing the ice. The ice maker includes an upper assembly including a plurality of hemispherical upper chambers, a lower assembly disposed below and pivotably coupled to the upper assembly, wherein the lower assembly includes a plurality of hemispherical lower chambers that are configured to come in contact with the plurality of hemispherical upper chambers to define a plurality of spherical ice chambers, a driver configured to pivot the lower assembly, and an ice-full state detection lever that is coupled to and configured to be pivoted by the driver, wherein the ice-full state detection lever is configured to pivot in the same direction as the lower assembly to detect whether the ice bin is in an ice-full state.
