1. A method for controlling a refrigerator, the method comprising:
sensing a temperature of a storage compartment;
operating a cool air supply at a first cooling power in response to the sensed temperature of the storage compartment being equal to or greater than a first reference temperature;
in response to the sensed temperature of the storage compartment becoming equal to or less than a second reference temperature that is less than the first reference temperature while the cool air supply is operating at the first cooling power, operating the cool air supply at a second cooling power that is less than the first cooling power;
in response to the sensed temperature of the storage compartment being less than the first reference temperature and greater than the second reference temperature while the cool air supply is operating t the first cooling power, operating the cool air supply at tai first cooling power;
in response to the temperature of the storage compartment becoming equal to a third reference temperature that is less than the first reference temperature while the cool air supply is operating at the second cooling power, adjusting the first cooling power of the cool air supply, and operating the cool air supply at the adjusted first cooling power; and
in response to the temperature of the storage compartment being less than the third reference temperature and greater than the second reference temperature while the cool air supply is operating at the second cooling power, operating the cool air supply at the second cooling power.
