Product details
Part B318-6000K is the main printed circuit board for 40-series Tandem Air uprights built by Riccar and Simplicity. The board carries the switching behind the handle-mounted controls, and it is the part to suspect once the cord, motor and switch have each tested fine on their own and the machine still will not run.
Board failures on this platform tend to show as a machine that ignores the switch completely, one that runs briefly and cuts out, or one that only works in certain positions of the handle, which points at a loose harness connector rather than the board itself. Photograph the wiring layout before disconnecting anything, since the connectors are not always keyed to fit only one way.
