The defrosting operation cycle control circuit of the refrigerator and the setting method thereof have conventionally performed the defrosting operation at a predetermined cycle according to the cumulative time of the operation time of the compressor. The defrosting operation is performed at an optimum time due to the use state of the refrigerator, and thus there is an advantage of preventing frequent changes in temperature and power consumption in the refrigerator during the defrosting operation.
