An automatic ice maker of a refrigerator has a housing, an ice-making container for making an ice by freezing the water making contact with the housing, a motor for generating the driving force to drive the ice-making container, the motor being accommodated in the housing and having a rotating shaft, a power transmitting apparatus for transmitting the driving force generated by the motor to the ice-making container so that the ice-making container is overturned or is returned to an initial position, a first micro switch for sending a first signal to a control unit for reversing a driving direction of the motor by making contact with the power transmitting apparatus, a second micro switch for sending a second signal to the control unit for closing an electric power applied to the motor by making contact with the power transmitting apparatus, and a third micro switch for sensing whether or not an ice cube storage bin which is disposed below the ice-making container is fully filled up with ice, and for sending a third signal to the control unit for stopping an operation of the ice maker when the ice cube storing bin is fully filled up with the ice. Since the automatic ice maker of a refrigerator controls the automatic ice maker by the plurality of the switches, it is easy to stably control the automatic ice maker, thereby decreasing the occurrence of a malfunction thereof.
