Garage doors ride on rollers inside two metal tracks, one on each side. When one or more rollers pops out of its track, the door can jam, hang crooked or twist. A door in that state is under uneven strain from its springs and cables and can come down without warning.
How to tell your door is off track
- The door is visibly crooked, with one side higher than the other.
- You can see rollers outside the track, or the track itself is bent.
- The door stopped partway and won't go up or down.
- There's a gap between the door and the track, or panels look bowed.
- A cable is loose, frayed or hanging off its drum at the top corner.
What to do right away
- Stop using the door and unplug the opener. Forcing an off-track door usually bends the panels and tracks further.
- Keep everyone clear, especially kids, pets and anyone who needs to get to a car.
- Don't try to force it back with a hammer, pliers or the opener.
- Don't pull the emergency release if the door is partly or fully open. If a cable or spring has failed, the door could drop.
- Take a few photos of both sides and the top corners. They help the technician know what to bring.
Common causes
Something hit the door
A broken or slipped lift cable
Loose or misaligned tracks
Worn rollers or hinges
An obstruction in the track
Why this is a job for a technician
Getting a door back on track safely usually means taking tension off the springs, supporting the door's weight, straightening or replacing track sections, and re-seating the rollers and cables. Every part of that involves the same stored spring energy that makes spring repair dangerous. Technicians also check for hidden damage, like a bent panel or a cracked bracket, that would cause the problem to come back.
What the fix usually involves
Depending on what caused it, the repair may include:
- Securing the door and releasing spring tension.
- Straightening or replacing bent track sections.
- Replacing a broken or frayed lift cable and re-seating it on the drum.
- Replacing damaged rollers or hinges.
- Re-tensioning the springs, balancing the door and testing the opener's safety reverse.
If a panel is badly bent, the technician may recommend a panel replacement or, on an older door, a full new door. Ask for both options in writing so you can compare.
How to prevent it
- Keep the tracks clear and wipe out debris a few times a year.
- Watch for rollers that wobble, squeak or look cracked.
- Don't ignore a door that starts to shudder, jerk or sound different.
- Make sure the opener's photo eyes are aligned and the auto-reverse works.
- Back out slowly. Most off-track doors start with a small bump.
