1. A method for controlling a refrigerator including a first tray configured to form a portion of an ice chamber, a second tray configured to form another portion of the ice chamber, a driving unit configured to move the second tray, an ice bin configured to store ice generated in the ice chamber, and an ice-fullness detection device configured to detect an ice fullness of the ice bin, the method comprising:
moving the second tray to a water supply position in a first direction;
performing water supply to the ice chamber based on moving the second tray to the water supply position;
based on completion of the water supply, moving the second tray to an ice making position in the first direction;
performing ice making after the second tray is moved to the ice making position;
determining the ice fullness of the ice bin while moving the second tray toward an ice separation position in a second direction opposite to the first direction after completion of the ice making;
based on the ice fullness of the ice bin not being detected while moving the second tray toward the ice separation position in the second direction, moving the second tray to the ice separation position to thereby separate the ice from the ice chamber;
moving the second tray to the water supply position in the first direction after ice separation is completed; and
before determining to supply water to the ice chamber the water supply position, moving the second tray in the second direction from the water supply position toward the ice separation position to thereby determine again the ice fullness of the ice bin.
