Abstract
A refrigerator includes: a cabinet in which a storage compartment is formed; a refrigerator door for opening and closing the storage compartment; a rack which can move from an initial position to a door opening position to open the refrigerator door; a driving motor which generates a driving force to move the rack; a power transmission unit which transmits power of the driving motor to the rack; a rotation detection unit which detects a rotation number of the driving motor; and a controller that controls the driving motor based on information on the rotation number detected by the rotation detection unit, in which the controller may control the driving motor to a first state until the rack moves from the door opening position to a reference position and may control the driving motor to a second state until the rack moves from the reference position to the initial position.
