Need to know... The output of the motor control circuit should only put 120VAC on one winding (CCW or CW) at a time? If I measure the output of the control board I seem to get 120VAC on both windings, at the same time.
The start capacitor checks good, so I'm thinking the Triac circuitry may have gone bad. It there a way the triac for the motor control can be replaced, instead of the whole control board? 
Whenever the motor is supposed to drive (spin, agitate) it just hums. As I said, there is 120VAC on both windings at this time. I would assume during spin, it should only have 120VAC on one winding (CW or CCW).... 

Have run the diagnostics and it keeps saying replace main control board. Seems there is a less expensive way to repair, $220.00 may be more than it is worth....

Check the caps on the control board to see if they're popped.

Will do.... have to pull the board back out...

Depending on how you are doing your volt reading on the motor windings the 120 volts to both windings at the same time could be misleading.

All loads on these units have a steady 120 Vac supplied to them when machine is powered up.  The triacs gate neutral to loads to turn them on/off.
