ABSTRACT:
An apparatus and method for controlling of a refrigerator automatic ice machine is disclosed. A first detection plate is installed on another end of the rotation shaft of the ice transfer motor, for detecting an initial position of an ice tray, the ice-fullness of the ice box and rotation angle of the ice transfer motor. A second detection plate is installed on one end of the ice-fullness lever, for detecting the ice-fullness of the ice box. A pulse generator generates pulse trains by the combination of movements of the first and second detection plates according to the driving of the ice transfer motor. A controller generates a forward or a reverse rotation control signal according to the pulse trains provided from the pulse generator and provides the forward or the reverse rotation control signal to the motor driver. According to the construction of the above, the ice fullness of an ice box of an automatic ice machine can be exactly sensed and errors in sensing the ice-fullness and driving an ice transfer motor can be prevented.
