  • Page 24: Icemaker Functions

    7-2 ICEMAKER FUNCTIONS 7-2-1 Start Position 1) When power is initially applied or reapplied after power is cut, it detects level of the TRAY after completion of MICOM initialization. The detecting lever moves up and down. 2) The level of icemaker tray is judged by output signal, high and low signal, of HALL SENSOR. Make the tray to horizontal by rotating ice ejection motor in normal or reverse direction so that High/Low signal can be applied to MICOM Pin (P22).
