A method for preparing clear ice includes supporting an ice tray via a rotating assembly within a housing and separating an interior volume of the housing into a first air chamber and a second air chamber. The first air chamber is below the ice tray and the second air chamber is above the ice tray. Water is supplied into the ice tray and the ice tray is cooled with a cooling device thermally coupled to a bottom surface of the ice forming plate. The cooling device is exposed to chilled air from within the appliance in the first air chamber. Ambient air is supplied from outside the appliance into the second air chamber within the interior volume of the housing. The surface of the water in the ice tray is exposed to the ambient air.

An ice maker includes an upper assembly provided with an upper tray which has an upper chamber recessed upwardly to define an upper side of an ice chamber in which water is filled to generate ice, a lower assembly provided with a lower tray which has a lower chamber recessed downwardly to define a lower side of the ice chamber, and a lower supporter which supports a lower side of the lower tray, in which the lower assembly is rotatably connected to the upper assembly. The ice maker also includes an upper ejector provided with an upper ejecting pin which separates ice from the upper tray after ice-making is completed, in which the upper ejector is connected to the lower assembly to be interlocked with each other, such that when the lower assembly is rotated, the upper ejector is lifted and lowered.
