A uniform cooling apparatus for a refrigerator and a control method thereof install a plurality of temperature sensors into a refrigerating compartment, mount an air circulation fan in addition to a prior refrigerating compartment fan into the refrigerating compartment, and thus obtain a uniform cooling effect by minimizing a refrigerating compartment temperature deviation. The uniform cooling apparatus includes: a plurality of temperature sensors which are mounted to at least two positions inside of the refrigerating compartment; and an air circulation fan which is additionally mounted to the refrigerating compartment, is turned on or off according to a deviation among temperatures sensed by the plurality of temperature sensors, and makes a uniform cool air in the refrigerating compartment. The uniform cooling control method for the refrigerator comprising the steps of: (a) sensing a refrigerating compartment temperature by using the plurality of temperature sensors; (b) calculating a temperature deviation among the refrigerating compartment temperatures sensed in the step (a); and (c) driving the air circulation fan if the temperature deviation is higher than a predetermined temperature deviation, and uniformly cooling the refrigerating compartment.
