Abstract: Provided is a refrigerator, which includes a main body, a door, an evaporator, a defrosting heater, a defrosting sensor, and a control part. The main body includes a food storage space and an evaporation compartment. The door selectively closes the food storage space. The evaporator is disposed in the evaporation compartment. The defrosting heater is disposed at a side of the evaporator to remove frost from an outer surface of the evaporation compartment or the evaporator. The defrosting sensor is disposed at a side of the evaporation compartment or the evaporator to sense a frost formation amount. The control part receives a sensed value transmitted from the defrosting sensor, and controls an operation of the defrosting heater according to the sensed value. A sensing period of the defrosting sensor is varied according to a frost formation amount sensed by the defrosting sensor.
