ABSTRACT:
An ice removal motor control circuit and method for an automatic ice maker is provided, which ice maker includes a load voltage detector for detecting a load voltage applied across an ice removal motor, a comparator for comparing the load voltage with a predetermined reference voltage, and a controller for outputting a control signal to an ice removal motor controller to stop operation of the ice removal motor when the load voltage is larger than the reference voltage. Thus, an excessive load is prevented from being applied to the ice removal motor, thereby protecting the ice removal motor and relevant elements from being damaged and further improving reliability of the automatic ice maker.
