ABSTRACT:
A control circuit for an auger type ice maker using a relay which is responsive to a predetermined level of an ice making water in a tank and to of a predetermined level of stored ice, and a timer circuit responsive to the commencement of the ice making cycle which corresponds to the detection of the water level and the completion of the ice making cycle which corresponds to the detection of the ice level, both by the relay. This timer circuit is arranged so that during the starting operation it starts to drive the auger motor at the beginning of the ice making cycle and then after a first predetermined time starts to drive the compressor, and during the stopping operation, it stops the compressor after a second predetermined time after the detection of the completion of the ice making cycle and then after a third predetermined time stops the auger motor. Should a short interruption of the supply of water occur, the timer circuit can ignore it because of its delay time. A backup function is also provided for the case of an abnormal ice level of stored ice.
