Abstract
A control method of a refrigerator to prevent frost from being formed in an ice making chamber. The refrigerator includes an ice making chamber refrigerant pipe to supply a refrigerant to make ice in a direct cooling manner and an ice making chamber circulation fan to create a forced air stream to circulate air in the ice making chamber. The control method includes determining whether temperature of the ice making chamber is lower than a predetermined temperature and driving the ice making chamber circulation fan in a state in which the temperature of the ice making chamber is lower than the predetermined temperature and the refrigerant flows in the ice making chamber refrigerant pipe or when flow of the refrigerant in the ice making chamber refrigerant pipe is interrupted in a state in which the temperature of the ice making chamber is lower than the predetermined temperature.
