WINE STORAGE CONTROL BOARD
LAYOUT AND SUMMARY TABLE
The electrical connection points on the wine storage control board
are labeled Alphanumerically. These labels correspond with the
alphanumeric control board summary layout table on the wiring dia-
gram. By referencing the table, it is possible to identify which com-
ponents are connected at which connection points on the control
board. Below is a layout diagram of the control board, followed by
a copy of a summary table. (See Figures 2-2 and 2-3)
NOTE: All components on the control board are non-replaceable.
If problems with the control board are identified, the complete con-
trol board must be replaced.
