Re: Broken Garage Door
Be extremely careful working on this particular roller. It has the counter-spring cable attached to it's bracket, which is under extreme load. If you start taking bolts loose or yank on that cable, it can come loose with very hazardous results!
You can probably work with a few basic tools and get the roller shaft back into position. Once you do that, make sure the shaft mounts are not bent which would cause a repeat of this situation.
I suspect that there is a bind somewhere causing the door to cant in the tracks, causing the shaft to come loose from it's moorings. Once you get the shaft back into place, disconnect the door opener and operate the door by hand a few times to see if you can find the problem. It could also just be loose hardware, make sure all the bolts at each hinge/roller are tight, then check the track for being tight and in proper working order, i.e., no damage.
I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!
