I just installed a new Genie Screw drive garage door opener. I adjusted the open and closing settings with no problem. When I open the door, no problem. When I go to close it, it gets about 1/2-3/4 of the way closed, the track looks like it bends upwards some, then pops and shakes a bit, and then closes.
This can't be normal. I've checked the heights, lowering the motor unit some and still had the same problem. Could it be the brackets that attach the motor unit to the ceiling, causing too much play? They don't look like the sturdiest things in the world.
I'm stumped... I've spent too many hours just staring at it trying to figure it all out... any help would be great!
