If you have a Marathon, there is no manual override. The worm drive has a clucthing mechanism when the TV swings down, but none when it swings into the ceiling. This is a flaw that destroys the worm gear, consequently with our 2002 XLII we needed the motor replaced. (Twice) We no longer have this problem, we no longer have the coach! Sorry
