2. CONTROLLER BOARD
Note: Refer to the controller board service manual.
IMPORTANT
If receiving a service call, ask the user to turn o󰀨 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.
* Handle the board by the edges only. Do not touch the electric parts and
devices.
