A refrigerator and a control method thereof to control a rotational direction of an ice making motor to detect an ice full state of an ice storage without separating the ice from the ice maker. The refrigerator includes an ice making tray making ice therein, an ejector separating the ice, an ice storage storing the separated ice, an ice full state sensing lever detecting the ice full state of the ice storage, an ice making motor driving the ejector and the ice full state sensing lever, and a controller detecting the ice full state by driving the ice full state sensing lever by rotating the ice making motor in an ice moving direction, and detecting release of the ice full state by driving the ice full state sensing lever by rotating the ice making motor in the opposite direction after the ice full state is detected.
