How to get garage door back in alignment?

To get garage door back in alignment when it is crooked, uneven, or binding in tracks, you need to realign tracks and ensure rollers, cables, and springs are balanced, with professional help recommended if springs or cables broken due to high tension danger. First, stop using automatic opener and pull emergency release cord to disconnect trolley so door can be moved manually without opener strain. Close door if possible, or clamp it with locking pliers on tracks below rollers to prevent falling, as door weighs 150 to 300 pounds. Inspect cause of misalignment: check if vertical tracks are loose and not plumb, using level to see if they lean, check if track mounting bolts loose, if rollers worn or out of track, if cables loose or off drums, or if springs broken causing uneven lift. If springs broken or cables off drums, call professional as high tension dangerous. If tracks loose and springs intact, loosen track mounting bolts slightly, not fully removing, and tap vertical tracks with rubber mallet to bring them back to plumb and spaced about half inch from door edge, and ensure horizontal tracks level. Use level to verify. Guide any rollers that have slipped out back into track channel by prying track open slightly with pliers and lifting door evenly with helper. Tighten bolts securely once tracks plumb. Lubricate rollers with silicone spray, test manual operation by lifting halfway to check balance, then reconnect opener and test automatic. Professional alignment costs 125 to 300 dollars.
