Abstract: A control method for a refrigerator comprises sensing a temperature of a first storage chamber; increasing an output of a first cooling fan if the temperature reaches a value greater than or equal to a second reference temperature; reducing the output of the first cooling fan if the temperature reaches a value less than or equal to a first reference temperature; increasing the output of the first cooling fan if a first reference time has passed after the temperature has reached the value or if the temperature chamber reaches a first setting temperature between the first reference temperature and the second reference temperature; and reducing the output of the first cooling fan if a second reference time has passed after the output of the first cooling fan has been changed, or if the temperature reaches a preset second setting temperature between the first setting temperature and the first reference temperature.
