CONTROL BOARD LAYOUT AND SUMMARY TABLE

The electrical connection points on the main control board are labeled alphanumerically (See Figure 2-2). These
labels correspond with the alphanumeric control board summary table, located on wiring diagrams (See Figure 2-3).
By referencing the summary table, it is possible to identify which components are connected at which connection
points on the main control board.
NOTE: All components on control board are non-replaceable. If problems with control board are identified, the
complete control board must be replaced.
