Greetings all, Info: My garage was built in the 1940s. It is a 4 unit garage for four condos, with no other access other than each garage door. To my knowledge all units have their own electric openers. My garage opener is a 15 year old champlain but it works well and I just replaced the internal gear coupling last year. Problem: As of 2 weeks ago my garage door stopped opening electronically or manually. It currently sits in closed position with a 2-4 inch opening on the bottom right, meaning it is slanted. I can view into my garage through the door window so I know that the left rail disengaged from the ceiling. This would explain the door trying to open on the right side but not the left. If I could get in their I could find a way to reattach the rail but currently that's not possible. The door appears to be wedged on its track. I was thinking of using a tire-jack to realign the door then manually release it. Has anyone ever had this problem? If so what steps did you take to fix it? Is this something I should just call professionals for? Thanks.

I'm installing a 7' tall, multi-section, Reliabilt, steel garage door and the door hits the roof. I'm considering cutting 4" off the bottom of the vertical tracks to get the door to clear the roof. But I'm unsure what this will do to the door operation. Does anyone have experience shortening the vertical tracks to lower the height of the door during opening? Did it have any adverse effect on the opening or closing of the door?
