Abstract: Provided are an ice maker, a refrigerator and a control method therefor, enabling the efficient separation of ice from ice making grooves in an ice tray at the time point when the ice making is completed, regardless of the size (capacity), operation rate, surrounding temperature and cooling capacity of a refrigerator. To this end, the ice maker, according to the present invention, comprises: an ice tray having ice making grooves formed therein; an ice separating motor driven so that ice is separated from the ice making grooves; a temperature detection unit; and a control unit for controlling the ice separating motor, wherein the control unit operates the ice separating motor or an ice separating heater at an ice separation starting time point or a heating starting time point calculated using temperatures detected according to time by the temperature detection unit, or a cumulative ice making time.

Abstract: Proposed are an ice maker and a refrigerator including the ice maker. The ice maker includes a drive motor arranged inside a casing and configured to rotate an ice-making tray or an ejector pin, a gear set operating in unison with the drive motor, an in-unison operating lever provided to operate in unison with the gear set, a magnet being provided on one side of the in-unison operating lever, and a printed circuit board arranged to one side of the in-unison operating lever, a position detection sensor being provided on the printed circuit board in such a manner that an electric contact point is established according to trajectory followed by the moving magnet.

Abstract: Provided are an ice maker, a refrigerator, and a method for controlling the same, which can accurately detect whether ice-making water in accommodated in an ice-making groove is full.
