Abstract: A refrigerator includes an evaporator, a defrost heater, a temperature sensor to detect a temperature associated with the evaporator, and controller to control the defrost heater. In response to a defrosting operation start time point arriving, the controller is configured to perform a defrost operation mode including a pre-defrost cooling mode, a heater operation mode, and a post-defrost cooling mode, perform a pulse operation mode in which the defrost heater is repeatedly turned on and off based on the heater operation mode, and change a magnitude of cooling power supplied in the post-defrost cooling mode based on an ON period of the defrost heater or a temperature of a cooling compartment in the pulse operation mode.
