Control Board Layout & Summary Table - Sub-Zero 700TC-3 Service Manual

Electronic Control System
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 the 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 and 3-3)
NOTE: All components on the control board are non-replaceable. If a problem with the control board is identified,
the complete control board must be replaced.
