Removal And Replacement - Hoshizaki DIM-40DE-HC Service Manual

7. REMOVAL AND REPLACEMENT

The replacement controller board is in common use for the entire IM_N models (HE).
To replace:
1) Unplug the icemaker or disconnect the power source.
2) Remove the front
3) Disconnect all the connectors from the controller board. Remove the controller board
from the control box.
4) Install the replacement controller board in the control box. Reconnect the connectors.
5) Replace the control box cover.
6) Plug in the icemaker or connect the power source. As the replacement controller
board has not been set for the proper model code, the 7-segment display illuminates
"00". When the controller board P01873-02 is used, the hyphen on the top left lights
up.
* The code "00" does not belong to any model.
7) Press the service 1 switch to increase the first digit in the 7-segment display, and the
service 2 switch to increase the second digit. The digit changes in the following order:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F, H. Set the proper model code according to
the model code list provided with the replacement controller board (see 3. [d] MODEL
CODE SETTING MODE). When a preset model code is displayed, the dot on the
bottom right lights up.
8) When the chosen preset model code is displayed, press the reset switch to store the
board memory (the display shows "on" and the machine will then always start up with
this memorized program as default).
9) Replace the front cover.
