A refrigerator of the present invention comprises: a storage chamber for storing food; a cool air supplying means for supplying cool air to the storage chamber; a first tray which forms a part of an ice-making cell in which water is phase-changed to ice by the cool air; a second tray which forms another part of the ice-making cell and can be in contact with the first tray during an ice-making process; a water supply valve for adjusting a flow of the water supplied to the ice-making cell; a water supply amount detector for detecting the amount of water supplied to the ice-making cell; and a controller for controlling the water supply valve. The controller controls the water supply valve to supply water to the ice-making cell as much as a first reference water supply amount, for supplying water to the ice-making cell at a water supply position of the second tray. After finishing the water supply as much as the first reference water supply amount, the controller moves the second tray to an ice-making position and determines whether the water supply amount of the ice-making cell has reached a target water supply amount by using the water supply amount detector. When the water supply amount of the ice making cell has reached the target water supply amount, the controller starts ice-making, and when the water supply amount of the ice making cell has not reached the target water supply amount, the controller moves the second tray back to the water supply position and controls the water supply valve to supply water as much as a second reference water supply amount which is less than the first reference water supply amount.

In a refrigerator, a cam of a cam gear rotating by a driving motor is provided with a structure protruding from an edge portion of a cam gear to a center, thereby increasing the thickness of a cam surface. Therefore, it is possible to reduce the magnitude of force directly transferred from the cam gear to a magnet lever.

A refrigerator appliance or ice maker may include an assembly frame, a rotating body, a thermistor wire, and a biasing spring. The rotating body may be rotatably attached to the assembly frame to rotate about an axial direction. The thermistor wire may extend between a static end and a movable end fixed to the rotating body to move therewith. The biasing spring may be fixed to the thermistor wire between the static end and the movable end. The biasing spring may be in biased engagement with the thermistor wire to motivate the movable end toward the static end.

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.
