An ice-making device of a refrigerator includes: an ice-making unit installed within a refrigerator and making ice cubes; a dispenser provided on a refrigerator door to allow the ice cubes to be taken out of the refrigerator; an ice duct guiding the ice cubes made in the ice-making unit to the dispenser; and an introduction preventing unit preventing an object from being introduced into the ice-making unit through the ice duct. A method for controlling an ice-making device of a refrigerator includes: inputting an ice cube extract signal; making ice cubes by driving an ice-making unit provided within the refrigerator and breaking the ice cubes according to the inputted signal; sensing an internal temperature of an ice duct that guides the ice cubes made in the ice-making unit to a dispenser provided on a refrigerator door; and stopping an operation of the ice-making unit when the sensed temperature is higher. Because an introduction of an external object into the ice duct is prevented and the operation of the ice-making unit is stopped, the external object can be prevented from being damaged, so the user can stably use the ice-making device of the refrigerator.
