Garage Door Opener Binding
Have just replaced my old GDO with a 1/2 HP Craftsman Screw type. Have a light sectional door and everything is working fine except for the last panel when closing. When it comes to the last panel, the door stops traveling and the opener keeps going until the linkage arm hits the top of the door.
Have checked the door manually and there are no binds and very easy to move up or down. When I do get it to move down all the way I notice the screw track trying to lift up from the header board. Would reinforcing the top of the door with a metal plate going across the three vertical ribs help? What else might be the problem? Thanks
