CONTROL BOARD LAYOUT AND SUMMARY TABLE
The electrical connection points on the control board are labeled alphanumerically. These labels correspond with
the alphanumeric control board summary table, located on wiring diagrams. By referencing the summary table, it is
possible to identify which components are connected at which connection points on the control board. Below is a
layout diagram of the control board and a copy of a summary table (See Figures 3-2 & 3-3).
NOTE: All components on control board are non-replaceable. If problems with control board are identified, the
complete control board must be replaced.
