My garage door is jammed. I think I know the problem but I have no other access to the garage besides the roll door.

I think the sleeve that slides the door along the opener track has caught somewhere. The openener hasn't worked for awhile and I have the sleeve unlocked to allow for free movement of the door. Pulling the release cable does nothing. Am I screwed?

Know the answer or have a comment? Post it here!

The load in the sheaves increases as the door lowers. They can look normal to the inexperienced eye. They can even look normal when off the door. Change all four, especially if the door used to work well. Make sure the front pulleys do not rub against the track assembly. Space them out with a washer.
