Here're some of my symptoms:

-the system does know that the door is open. It definitely knows when the door is closed
-the belt moves out of the way sometimes one sec to 30 sec pause after the door is open.
-coincedentally, if you manually release the belt, then it moves out of the way.

The signal to tell the motor to run, I assume are: door trigger is open or the dome lights are on. Dome lights always come on as they should so I don't think it is telling the belt system to turn on. So there must be a sepate signal coming from the door trigger, which I assume is negative switching.

I mentioned relays because the motor may draw an amp or two, specially as the track wears due to age and not properly lubricated. Typically, relays are used to switch current but i don't know what's happening in this case.

The search continues....!
