Abstract: The present disclosure relates to a refrigerator. The refrigerator includes an evaporator, a defrost heater, a temperature sensor to detect an ambient temperature of the evaporator, and controller to control the defrost heater, wherein, 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 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. Accordingly, defrosting efficiency and power consumption may be improved, and cooling power after defrosting may be efficiently supplied.
