Abstract: A method of controlling a refrigerator may include operating a first cooling cycle for a first storage compartment to drive a compressor and operating a first cooling fan for cooling the first storage compartment, and switching to a second cooling cycle for cooling a second storage compartment to drive the compressor and operating a second cooling fan for cooling the second storage compartment when a stop condition of the first cooling cycle is satisfied. The method may also include switching to a third cooling cycle for cooling the first storage compartment to drive the compressor and operating the first cooling fan when a stop condition of the second cooling cycle is satisfied.
