Abstract: A method for controlling the refrigerator includes turning off a cold air transmission unit and operating a cold air generator with cooling power, which is previously determined, as the temperature of the second storage compartment is equal to or less than a second reference temperature, turning on the cold air transmission unit and operating the cold air generator with the cooling power, which is previously determined, when the temperature of the storage compartment is equal to or greater than a first reference temperature, calculating, by a controller, an operating ratio of the cold air transmission unit based on an ON time and an OFF time of the cold air transmission unit, upon determining that the temperature of the storage compartment is equal to or less than the second reference temperature and adjusting the cooling power of the compressor based on the operating ratio of the cold air transmission unit.

Abstract: A method for controlling a refrigerator includes providing an initial input value to a heater configured to supply heat to an evaporator, performing a continuous operation of the heater based on the initial input value to increase a temperature of the evaporator to a predetermined temperature, determining a period of time taken to increase the temperature of the evaporator to the predetermined temperature, determining whether the period of time is within a reference period of time, operating the heater based on a first input value that is equal to the initial input value based on a determination that the period of time is outside of the reference period of time, and operating the heater based on a second input value that is less than the initial input value based on a determination that the period of time is within the reference period of time.
