Hi, Have a old dover on service that has drove my nuts! The unit has damping motor that is running in only the dn dir,but when going up the unit runs slow speed and the damping motor does not spin. The unit has a 16/15 relay were most compsites have a 14/15 relay. I know there is a issue with the damping motor.The damping motor was rewound and I think this was wound wrong. I can email prints if someone can help,Thanks
