The invention discloses a refrigerator and a defrosting method thereof. The defrosting method comprises the following steps that the minimum frosting time and the maximum frosting time which are allowed by accumulated running time of a compressor and the minimum frosting time and the maximum frosting time which are allowed by power-on time are set; starting from the refrigeration shutdown time after defrosting, N compressor starting and shutdown cycle times are continuously recorded, whether door opening, environment temperature changing and set temperature changing occur in one cycle or not is judged, ad if yes, whether the refrigerator enters defrosting or not is judged according to the accumulated running time of the compressor; and if not, whether the refrigerator enters defrosting or not is judged according to the minimum frosting time and the maximum frosting time which are allowed by the accumulated running time of the compressor or the power-on time. According to the refrigerator defrosting method, th
