A refrigerator comprising: a refrigerator body; a refrigerating compartment defined at a first portion of the refrigerator body; a freezing compartment defined at a second portion of the refrigerator body, the second portion of the refrigerator body being different than the first portion of the refrigerator body and the freezing compartment being separated from the refrigerating compartment by a barrier; at least one evaporator configured to cool air used in regulating operating temperatures in the refrigerating compartment and the freezing compartment that differ, with the freezing compartment having an operating temperature that is lower than an operating temperature of the refrigerating compartment; a refrigerating compartment door that is configured to open and close at least a portion of the refrigerating compartment; a freezing compartment door that is configured to open and close at least a portion of the freezing compartment; an ice compartment positioned at the refrigerating compartment door and configured to receive cool air from the freezing compartment; an ice maker positioned within the ice compartment and configured to freeze liquid water into ice; a full ice sensor configured to detect completion of ice making by the ice maker; one or more door ducts (120, 130) positioned at the refrigerating compartment door and configured to guide cool air from the freezing compartment to the ice compartment; a refrigerating compartment supply duct configured to guide cool air from the freezing compartment to the refrigerating compartment; a refrigerating compartment return duct configured to guide cool air of the refrigerating compartment to the freezing compartment; a first unit that is positioned at the barrier that separates the freezing compartment and the refrigerating compartment, that is configured to connect, through one or more passages in the barrier (211,212), the one or more door ducts to the freezing compartment when the refrigerating compartment door is oriented in a closed position, and that is configured to close the one or more passages in the barrier when the refrigerating compartment door is oriented in an opened position; and a second unit positioned at the ice compartment and configured to open and close a passage defined in a wall that separates the ice compartment from the refrigerating compartment, the second unit configured to communicate with the ice compartment and refrigerating compartment based on whether or not ice making by the ice maker has been completed. a refrigerator body;
