IPC: F25C1/04
Abstract: A method for controlling a refrigerator according to the present embodiment is a method for controlling a refrigerator comprising a first tray forming a part of an ice chamber, a second tray forming another part of the 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 comprising the steps of: supplying water to the ice chamber in a state in which the second tray has moved to a water-supply position; making ice after the second tray has moved from the water-supply position to an ice-making position in the inverse direction after the water supply has been completed; determining whether or not 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 same in the inverse direction if it is not determined in the step of determining whether or not the ice bin is full of ice that the ice bin is full of ice; and determining again whether or not the ice bin is full of ice after ice separation is completed.
