The attached link may help.......the videos show methods of resyncing the motors or manually overriding them, but I am not sure if the ACE motor controller is easily accessed. I think mine is behind paneling on the passenger side near the ceiling......no easy access panel that I can see; but we don’t use our bunk. (hope my link works). I would also ensure the bunk is not hung up on the slide track somehow (ACE "may" have a different bunk drop/slide system than other coaches but still uses the dual motor controller I believe).
