Machine Control
The machine control microprocessor board is located in the control console, mounted to the plastic console. The board receives input from the membrane pad/touch screen, door lock switches, and the unbalance switches. The control also communicates with the motor control board to facilitate the various cycles and drive the motor for optimum performance. This is done by monitoring torque and speed of the motor through the motor control board.
Figure
Both incoming and exiting voltage is monitored through the machine control board and the surrounding circuitry. The following table lists the voltages for the various terminals on the microprocessor board. If proper voltage is not present, check switches and wiring for possible loose connections or open circuits by disconnecting the power supply and performing continuity checks of individual circuits. NOTE: Connector P8(2) (White wire) is Neutral input and L1 input is the connector P6(2) (Black wire), L1 output is connector P6(3) (Black wire).
The machince control board outputs can be verified by placing the washer into the Service Mode and performing a Board Output Test. (See Section 2; Service Mode;
Board Output Test.)
