Duet dryer is non-responsive on automatic cycles but keypad self tests okay

Hello,

I have a dryer that I think is having a problem with the control board. If I put the selector on an automatic cycle with the controls off, the controls are non responsive. If I put selector on manual cycles, it works just fine.. If I put the selector in between manual and automatic cycles, it turns on with the control on button, and if I quickly move the selector to an automatic cycle it starts and runs the cycle just fine.. It seems like the electronic control (one with the selector) is bad, but I run the self test and it reports all selector, led and button functions operating correctly. This makes me think I have a bad control board (the one on the side of the cabinet.) Have you ever seen this particular behavior? Does my logic make sense regarding which board is bad?

Thanks for your time,
Jason
