The present invention relates to a control method of a refrigerator which operates a cooling cycle including two storage compartments, a compressor, a condenser, a valve, fans, and evaporators for cooling the respective storage compartments, with one of the fans (5) corresponding to the storage compartment for storing items at relatively low temperatures being activated for a set amount of time even after the compressor is deactivated at the completion of cooling of the storage compartment for storing items at relatively low temperatures. In a refrigerator comprising a first storage compartment for storing an item, a second storage compartment for storing an item at a lower temperature than the first storage compartment, a cooling cycle including a compressor, a condenser for condensing a refrigerant from the compressor, a valve for directing the refrigerant from the condenser to first and second evaporators, with the first and second evaporators evaporating supplied refrigerants to cool the first and second storage compartments, respectively, and first and second (5) fans for circulating cool air from the first and second evaporators, respectively, and a controller for controlling…
