The invention discloses a control method for preventing a refrigerating chamber from freezing, a storage medium and a refrigerator. The method comprises the steps of judging the current temperature mode of the refrigerating chamber when the opening and closing operation of a door of the refrigerating chamber is monitored; judging whether first temperature collected by a first temperature probe in the refrigerating chamber is higher than a preset first temperature threshold when the current temperature mode is a normal mode; if the first temperature is higher than the first temperature threshold, monitoring whether the duration that the first temperature is higher than the first temperature threshold reaches a preset duration threshold; and if the duration reaches the duration threshold, switching the temperature mode of the refrigerating chamber into an anti-icing mode. According to the control method, whether heat load food is put near the temperature probe in the refrigerating chamber is judged, so that the temperature mode is automatically switched to the anti-icing mode, and the anti-icing operation is performed so as to prevent other food in the refrigerating chamber from icing and freezing because the air door of the refrigerating chamber is opened for a long time.
