Garage door off its track, or a cable off the drum
If the door is crooked, one side has dropped, or a cable is hanging loose, stop using it and keep everyone out from under the opening. This is one of the two faults we ask you not to touch.
Leave this one alone until we have looked at it.
A torsion spring holds a great deal of energy, and a door off its track can fall. Neither is a job to try with the tools in a garage. Do not force the door or touch the release cord while it is up.
This is emergency work. Leave the door where it is and tell us what it did.
Why a door off its track can fall
A sectional door is held in two places at once. The rollers keep each panel inside the vertical track, and the lift cables carry the weight of the door up to a drum at either end of the shaft. Those two systems only work as a pair. Lose a cable on one side and the load transfers to the other, the door racks out of square, and the rollers on the loaded side are forced against the track until they leave it.
Once that has happened, nothing is holding the door to a fixed path. Running the opener drags a door that is already out of line, which is how a track gets pulled off the wall and how panels get bent past repair. Pulling the release cord while the door is part way up disconnects it from the opener carriage, which may be the only thing still resisting the drop.
Do not force the door, do not pull the release cord while it is raised, and do not try to lever a roller back into the track. A door in this condition is heavy enough to injure someone standing under it.
What has usually failed
A cable off the drum
The cable has unwound or jumped its groove, often after the door closed onto something and went slack while the drum kept turning. The door may still move, but it hangs low on one side and binds against the track.
A snapped cable
Cables fray from the bottom up, where water and grit sit around the bottom bracket. When one lets go under load, that corner of the door drops at once and the door jams in the opening at an angle.
A roller out of the track
Usually an impact, a worn hinge, or a track knocked out of line by a bumper. One panel sits proud of the opening and the door will not travel past that point.
The door is crooked but the cables look intact
If you heard a loud bang from the garage and the door now lifts a few inches and stops, the fault is more likely above the door than beside it. Read what a broken spring looks like. A torsion spring stores a great deal of energy and is not something to inspect by hand.
What we do about it
We straighten and re-track the door, replace failed cables in pairs, and check the drums, bearings and bottom brackets that let the cable fail in the first place. Where a track has been distorted or a panel has taken the load, we say so and do not reinstall a bent part. That work sits under cable and track repair, within our wider garage door repair.
The inspection and estimate are free whether or not you approve the work, and every cable or track part we install is named on the invoice with its specification.
- A door off its track is one of the faults covered under emergency garage door repair.
- If the panels are damaged, a new door may be the better answer than rebuilding the old one. You can see one on your own house first.
- What moves the figure is set out in what affects the price, and you can ask about financing.
If the door is safe where it stands and you prefer not to phone, request a free estimate. Other faults are listed under garage door problems. We cover all of Los Angeles County.
