The invention provides a control method of an air-cooled refrigerator. The air-cooled refrigerator comprises a refrigerating chamber, a refrigerating chamber door, a refrigerating evaporator, a refrigerating draught fan, a temperature sensor used for detecting the temperature of the refrigerating evaporator and a compressor, wherein the refrigerating evaporator and the refrigerating draught fan are used for refrigeration of the refrigerating chamber. The refrigerating evaporator is arranged to be capable of being controlled to communicate with or not communicate with the compressor. The control method comprises the steps that when the refrigerating chamber door is opened under the condition that the refrigerating chamber is in the refrigerating state, the refrigerating draught fan is switched off until the refrigerating chamber door is closed, and the refrigerating evaporator and the compressor are kept communicating with each other until the refrigerating chamber door is closed or until the temperature of the refrigerating evaporator is lower than a first temperature threshold value. According to the control method of the air-cooled refrigerator, the refrigerating draught fan is controlled to be always switched off under the condition that the refrigerating chamber door is opened, so that the situations that due to the fact that the refrigerating chamber door is opened, wet and hot air entering the refrigerating chamber circulates to the refrigerating evaporator, and more wet and hot air is sucked into the refrigerating chamber are avoided, it is avoided that the humidity and/or the temperature in the refrigerating chamber change/changes greatly, and therefore the preservation effect of the air-cooled refrigerator is continuous and stable.
