ABSTRACT:
The automatic ice making device includes ice sensor for detecting ice-making in ice chill tray, heater for heating ice to separate the ice from ice chill tray, motor rotating discharging member for discharging ice from ice chill tray, position detecting switch for detecting rotating position of discharging member, ice storage amount detecting switch for detecting overs and shorts of discharged and stored ice, water supply valve for supplying water to ice chill tray, and controller for controlling electric conduction to heater and motor. When power supply to controller is once interrupted and re-started, ice storage amount detecting switch detects shortage of ice so as to hold motor not to drive until ice sensor detects temperature below a predetermined temperature.
