Before anything else

The first few minutes,in this order.

None of these needs tools, and none of them puts you under the door.

1. Stop pressing the buttonAn opener doesn’t know the door has left the track. Every press drives the door harder against whatever is holding it, which is how one roller out becomes a folded section and a bent rail. Take the remotes out of the cars, and tell everyone in the house not to touch the wall button or the keypad.
2. Cut the opener’s power, if you can do it safelyThe safest way is the breaker for the garage outlet, if you know which one it is. Unplugging the opener is fine too, but only if you can reach the plug without standing under the door or leaning a ladder against the track. If the only way to the plug is under the door, leave it and keep people out instead.
3. Clear the area, and keep it clearKeep children, pets and cars out of the opening and out from under the open part of the door. Don’t drive in or out under it, even if there seems to be room. A door that has shifted once can shift again without anyone touching it.
4. Keep your hands off the doorDon’t lift it, don’t pull it down, and don’t try to guide a roller back into the track. Leave the emergency release cord alone too. If a spring or cable has let go, the opener may be carrying part of the door’s weight, and releasing it can let the door drop.
5. Look from a distance, and take photosNote which side is affected and where the rollers are out: near the floor, at the curve, or up by the ceiling. Look for a slack or dangling cable, a gap in a spring above the door, and dents in the sections. Photos from where you stand help us bring the right parts, and they help an insurer if a car was involved.
6. Call, and say what you seeTell us whether the door is open, closed or hanging, and whether a car is behind it. If a car is trapped, the spring safety guide covers what can and can’t be done safely, and an emergency call is the way to reach us fastest.

The cause

Why doors come off their tracksand why the cause matters most.

A roller doesn’t leave a straight, well-fastened track on its own. Something pushed it out, pulled it out, or let it drop, and putting the roller back without finding that is how the same door is off track again next month.

Something hit it

The most common cause by a distance is a vehicle. A car reversed into a door that wasn’t fully up, or nudged a closed door, bends the sections inward and pushes the rollers out of the track at the point of impact. Bikes, trailers and a mower backed in at an angle do the same on a smaller scale.

An impact rarely damages only the rollers. The track is usually kinked where the rollers were forced out, and the sections that took the hit may have bent hinges or cracked stiles. That’s why a door that was hit should be looked at even if it seems to run afterward.

A lift cable let go on one side

The door hangs from two steel cables, one at each bottom corner, wound onto drums at the top. If one cable frays through, snaps, or slips off its drum, that side loses its support. The door tilts, the rollers on the low side bind, and the high side can ride out of its track.

This is the off-track door that most often gets made worse, because it can look like a track problem when it’s really a cable problem. The cable is under tension from the springs, so it’s look-only. Cable repair has its own page, and a door that went crooked right after a loud bang may have a broken spring behind it.

The opener kept pulling

An opener pushes and pulls the door with steady force. If the door can’t move, because a slide lock is engaged, something is in the way, or a spring has failed and the door is too heavy, the opener can drag one side ahead of the other until rollers pop out.

A correctly set opener stops or reverses before that happens. One whose force has been turned up to push past a sticking door won’t. That setting is technician work, and the reversing guide explains why raising it is never the fix. A door that simply won’t lift is a different problem, covered in our guide to a door that won’t open.

The track worked loose or out of line

Each vertical track is held to the wall by brackets, and the ceiling tracks are held up at the back by supports hung from the framing. When those fasteners loosen, the tracks drift apart or out of line, the rollers ride near the edge of the track instead of the center, and one day a roller comes out at the weakest point, usually the curve.

You can sometimes see it coming: a gap that looks wider at the top than at the bottom, a track that visibly moves when the door runs, or a door that has started to wobble or rub on one side.

Worn or broken rollers

A roller with a worn wheel, a seized bearing or a bent stem doesn’t roll; it drags, climbs, and eventually jumps out. Older steel rollers without bearings are the usual culprits, and they tend to announce themselves first with grinding and squealing, which the noise guide sorts by sound.

A single cracked roller is often what lets an otherwise sound door come out at one spot. Replacing the set usually costs less than repairing what a failed roller eventually does to the track.

Something in the track

Less often, it’s simply something in the way: a tool left on the bottom of the track, packed dirt or gravel at the floor, or a storage rack or bike hook that the door catches as it goes up. The rollers climb over it and come out. If you can see the cause at floor level with the door closed, it’s fine to remove it, but don’t run the door to test it; the roller that climbed out still has to be put back properly.

On the visit

What a proper repair involves,in the order it has to happen.

The order matters more than any single step. A door is made safe before anyone touches a roller.

Secure the door first. Before anything is loosened, the door is clamped or blocked so it can’t move while the rest of the job is done.

Check the springs and cables before the rollers. If a cable has come off its drum or a spring has failed, that is dealt with first, with the load taken off in a controlled way. Reseating rollers on an unbalanced door only puts it back in the same position.

Get the rollers back in, or replace them. Rollers are eased back into straight track, and any that are cracked, worn or bent are replaced rather than reused.

Straighten or replace the track. A kink where the rollers were forced out gets straightened if the metal allows it, or that length of track is replaced. The vertical tracks are set true and the right distance apart, and the ceiling tracks are rehung level on their rear supports.

Tighten or replace what let go. Brackets, hinges and fasteners that loosened or bent are tightened or replaced. A section that took an impact is assessed, and replaced only if it can’t be made sound.

Balance and test. The door is balanced and run by hand before the opener is reconnected. Then the opener’s limits and force are checked, and both safety tests are done: the photo-eye test and the contact-reversal test with a 2x4 laid flat under the door.

Most off-track repairs are finished on the visit when the track can be straightened and the sections are sound. A badly bent section, or a door that has been off track more than once, sometimes means ordering parts, and occasionally means a conversation about the whole door. Either way, you see the damage and the price is agreed before work starts.

On the visit

What we do when we come outto a door that’s off its track.

We make the door safe before we touch it, then find out why it left the track. That usually means looking at the cables and springs before the rollers, because the rollers are rarely the whole story.

You see what failed before any work starts, and the price is agreed before we pick up a tool. When we leave, the door has been balanced by hand, run on the opener, and put through both safety tests, including the contact-reversal test with a 2x4 laid flat.

We work across all of Riverside County from our shop on Industrial Avenue in Riverside, and looking at a door costs nothing.
