Only Cancel works on KitchenAid

Any of the green lights go on when they are selected, but only the cancel button starts the motor. Something that may be a clue is that we always used heavy wash and that stopped working. So when testing the door switch (which has gone bad in the past) I put it on Normal wash and it came on. Since the door was open, I stopped it. It hasn’t come on again since. Then, the same thing happend with Light wash. Came on once, never again. Now only cancel is working.

Could this be the electronic control board and is there a sure way to test it?

Any suggestions on anywhere else I might troubleshoot?

Thanks
