Safety: Garage doors are heavy and spring/cable systems can be under significant tension. Do not loosen or disassemble high-tension hardware unless you are qualified to do so.
Track Problems to Watch For
Visible bends, gaps around rollers, rubbing, scraping, or sections pulling away from the wall can indicate track or mounting trouble.
Track Problems Affect Other Parts
Poor alignment can place extra stress on rollers, hinges, cables, and the opener.
Do Not Hammer a Loaded Track
When a door is partly open or under load, forcing track components can make the door unstable. The safe repair method depends on the door's position and condition.
