A sectional door rides up and back on small wheels, the rollers, that run inside two steel tracks. When rollers leave a track, the door stops being guided: it tilts in the opening, binds halfway, or scrapes and grinds as it moves. Something usually pushed it there. A bumper touched the bottom panel, a bin was in the way when the door came down, a cable let one side drop, or a track bracket worked loose over time.
What you may see
- Rollers sitting outside the track, usually near the bottom or at the curve where the track turns back toward the ceiling.
- A gap between the door and the frame on one side, or a panel bowed where it was pushed.
- A track bent inward or pulled away from the wall.
- Grinding or popping as the door moves, and an opener that stops and reverses.
Why not to force it back
An off-track door is still hanging on its springs and cables, and it is no longer running where it was designed to run. Pushing rollers back in, prying a track straight or letting the opener drive the door through the bind can move the whole door suddenly. The Consumer Product Safety Commission puts it in one line:
If doors are not "balanced," or if they bind or stick, they should be serviced by a professional.
— CPSC Publication 523
What to do until someone comes
- Stop using the opener. Unplug it if you can reach the plug without standing under the door.
- Keep people and cars out of the opening.
- Look for a broken cable or a gap in a spring from where you stand. A door that left the track because a cable let go is a different job from one that was bumped.
- Take photographs before anything is moved if a vehicle was involved.
What the visit covers
A technician secures the door, puts it back in its tracks, and replaces rollers, hinges, track sections or brackets that were bent. Because a door that came off track may also have stressed its cables and springs, those are checked too. The price is named after that inspection. When the work is done the door should run straight, stay balanced, and pass the monthly reverse test described in residential opener manuals.
