1. A method for controlling operation of a refrigerator comprising a plurality of storage chambers, a plurality of evaporators installed respectively in the plurality of storage chambers, and a refrigerant passage switching valve to switch refrigerant passages connected to the respective evaporators, the method comprising:
sensing temperatures of the plurality of storage chambers to determine whether the temperatures of the storage chambers reach preset temperatures;
stopping operation of a compressor if the temperatures of the storage chambers reach the preset temperatures; and
controlling the refrigerant passage switching valve after stopping operation of the compressor so that the refrigerant passages to the plurality of evaporators are closed.
