Thank you for all that information. Unfortunately the problem is the console.
In this case the console has a failed component. They only sell new consoles for this not electronic parts individually.
That said, you need a new console. Its easy to replace, no soldering required everything plugs into the console.
I will help if you need me, no extra cost ;-)
The best place to get the new console for this model is: Treadmill Doctor:
TOLL FREE 8am - 5pm Mon - Fri CST

In any case, I will stick with you until this is complete.
