ELECTRONIC CONTROL BOARD
Control Board
General
P-Model control boards use a dual voltage
transformer. This means only one control board is
needed for both 115V and 208-230V use.
The control board along with inputs controls all
electrical components, including the ice machine
sequence of operation. Prior to diagnosing, you
must understand how the inputs affect the control
board operation.
Refer to specific component specifications
(inputs), wiring diagrams and ice machine
sequence of operation sections for details.
As an example, refer to “Ice Thickness Probe” in
the service section of this manual for information
relating to how the probe and control board
functions together.
This section will include items such as:
• How a harvest cycle is initiated
• How the harvest light functions with the probe
• Freeze time lock-in feature
• Maximum freeze time
• Diagnosing ice thickness control circuitry
