An automatic icemaker for a refrigerator. The icemaker has an ice tray, an ice receiving container for receiving ice pieces formed in the ice tray, a water reservoir for storing a water to be supplied to the ice tray, a pump installed at one side of the water reservoir, a supply hose for guiding a water pumped by the pump to the ice tray, an overflow hose for recirculating a water overflowing from the ice tray to the water reservoir, and a sensor for detecting the overflowing water by making contact with the overflowing water and sending an electric signal to an ECU so as to stop a water supply. The pump continuously supplys a water to the first vessel, and when the sensor makes contact with the water, the sensor sends an electric signal to the ECU and the ECU stops an operation of the pump. The icemaker continuously supplys water until the water fills up the ice tray so that the control circuitry thereof is simple, and guides the overflowing water to the water reservoir so that the forming of an unnecessary ice in an ice making compartment is avoided.
