The above ICE-MAKER circuit is a circuit diagram of KIT in the Freezer.
Operation of AC solenoid at Machine Room through RELAY and then, opening and closing of
VALVE supplies water to the ICE-TRAY.
This circuit is H/W for the function of Eject, Horizontality noise, Ice-Making Thermal-Sensing,
and Full-Ice Sensing.
Thermal-Sensing part of this circuit is the same as that of MAIN H/W and circuit of HOR/INV S/W,
LEVER S/W is the same as that of DOOR S/W of MAIN H/W.
So, only circuit of EJECT MOTOR operation is described as follows.
By rotating clockwise Motor, HIGH signals outputted from MICOM PORT NO #9 is inputted to
1C05 @ and by output from IC05 17, the current is supplied to IC04 @ through MOTOR.
At this time, since © terminals of IC04 is connected with CCW PORT, IC04 @ output PORT turns ONand
MOTOR operates counter-clockwise by the current to GROUND.
On the clockwise operation, CW PORT #8 is outputted as HIGH and Eject, Horizontality noise and so on are
operated by the clockwise operation of the relevant IC PORT.
For the instruction of the above circuit related with detailed operation, refer to the function descriptionof ICE-
MAKER of this SVC MANUAL.
