Abstract: A refrigerator includes a first heater, a second heater, and a third heater, and the third heater is located inside a frost detection flow path and generates heat. Accordingly, during a defrosting operation, the inside of the frost detection flow path may be prevented from being blocked. Or freezing of the frost check sensor provided in the frost detection flow path may be prevented.
