2. CONTROLLER BOARD
Note: Refer to the controller board service manual.
IMPORTANT
If receiving a service call, ask the user to turn off the power to the icemaker
and turn it on again, while watching the icemaker. This will reset the
controller, and in some cases normal operation will resume.
CAUTION
1. Check that the icemaker has been earthed properly. If not, the controller
board will not work properly.
2. Do not change wiring and connections, or the controller board will not
work properly.
3. Do not touch the reverse side of the controller board and tiny electronic
devices on it.
4. Do not repair the electronic devices and parts on the controller board
in the field (except for fuse replacement). Replace the whole board
assembly when it fails.
5. To get static free, always touch the metal part of the icemaker before
servicing. Electrostatic discharge will cause severe damage to the
controller board.
6. The signal ground wire must be connected to the control box when
replacing the controller board after service.
7. The controller board is fragile. Handle with care.
* Do not drop the board on the oor.
* Make sure that the board is placed correctly into the guides in the
control box. Mis-alignment could cause breakage when replacing the
control box cover.
* Handle the board by the edges only. Do not touch the electric parts and
devices.

Evaporator
Thermistor
2. Bin Control Switch
Procedure
CAUTION
Thermistor sensor part is fragile,
glass sealed. Handle with care.
* Disconnect the connector CN13 on
the board.
* R e m o v e t h e s c r e w a n d t h e
thermistor holder on the evaporator.
* Immerse the sensor part in a glass
co nt a i n i n g i c e a n d wat e r for 5
minutes.
* Check the resistance between CN13
connector pins.
* Replace the thermistor in its correct
position.
* Connect CN13.
Manually set the micro switch in the
TRI P and RE S ET p os i tio n s, and
check the period.
