A refrigerator and a method for controlling the same are provided to reduce a manufacturing cost by not installing a temperature sensor and a defrosting temperature sensor. A method for controlling a refrigerator includes the steps of: sensing a temperature of external air(S101); setting on/off time of a compressor and a defrosting time of a defrosting heater on the basis of the sensed external temperature(S102); cooling a freezer in accordance with the set on/off time of the compressor(S109); and turning on the defrosting heater if the freezer is needed to be defrosted, and turning off the defrosting heater after a predetermined set time(S115,S117). |
