The present invention relates to a heater controller and a heater control method of a refrigerator, and more particularly, to a heater controller and a heater control method of a refrigerator, which control a heater mounted in a refrigerator dispenser. In the present invention, a dispenser of a refrigerator door is provided with a water tank. In order to prevent water in the water tank from being frozen over, the heater is mounte d at an outside of the water tank. In addition. by measuring an outer surface temperature of the water tank and then recognizing a water temperature in the water tank based on the oute r surface temperature of the water tank, the heater is controlled to be turned on/off based on a range of the water temperature in the water tank. Furthermore, in the present invention, an ambient temperature at a position of the refrigerator is measured, and then, the heater outputs heat energy according to a range of the ambient temperature. Then, t he heat energy of the heater is transmitted to the water tank. As a result. the wate r temperature in the water tank is properly controlled, so that the water tank is prevented from being frozen over.
