Kenmore Dishwasher No Start

Kenmore Model 66513742K601 installed Dec’07 now will not start. Only indications of power are High Temp, Sani Rinse and Heated Dry Options will press and
get green light. All other buttons dead. Door lock switches and fuse on
control board all ohm check good. Door lock appears to engage switches OK.
Checking door switches by depressing them both with door open still
doesn’t produce power. Should I suspect bad control board? Is there
anyway to test it without replacing it with new? Any DIY diagnostic
that I have over looked?
