Got a Smartrise controller with this door operator and getting a serial comm loss fault and occasional encoder fault. If I put controller on door disconnect it’ll run all day. On normal, when door opens, it hits DOL but door motor keeps running. Already swapped motor/encoder with other car, no change. Looking for suggestions. Thanks

No it’s wired discrete that is from the Smarttech II. Just not sure why it is giving that fault.

I would look at the door board next.
