A garage door cable coming off is one of the easier problems we fix. When you catch it early and leave the door alone, it usually stays a small job. When you keep forcing the door, it can turn into a big one in a hurry.
We just saw that happen. A homeowner had a cable come off, figured he could handle it, and kept forcing the door. By the time we got there, more than half the rollers had come out of the track and the door was falling out of the opening. We got it back in the track, and now it closes level again. Here is the short video from that job:
Watch on YouTube: cable-off door forced out of its track. There is also a 20-second Short.
I want to walk you through what a cable-off door is, why forcing it makes things worse, what usually causes it, and when it is time to put the tools down and call us. If you are standing in your garage right now looking at a loose cable, read the next section first.
If your cable is off right now, do this first
- Stop using the opener. Do not keep hitting the wall button or the remote. Every run puts more stress on a door that is already out of balance.
- Do not force the door up or down by hand. This is exactly how the door in our video ended up out of its track.
- Leave the door where it is. If it is stuck partway, let it stay there. Do not try to “help it” the rest of the way.
- Keep people, kids, pets and cars clear. Do not walk or park under a door that is crooked or has a cable hanging.
- Call us. Tell us what you see: which side the cable is off, whether the door is crooked, and whether any rollers look like they are out of the track.
What a cable-off garage door actually is
Most homes around Houston have a sectional garage door with torsion springs on a bar above the opening. On each end of that bar is a drum, and a steel lift cable runs from each drum down to a bracket at the bottom corner of the door.
The springs do the heavy lifting. The cables are how that spring force gets to the door. When everything is working, both cables wind and unwind evenly on their drums, both sides of the door move together, and the rollers ride smoothly up and down in the tracks.
A “cable off” means one of those cables has come off its drum, gone slack, or slipped out of place. Now one side of the door is being lifted and the other side is not. That is when you see the door hanging crooked, one side lower than the other, or a loose cable dangling by the track.
Why it matters: a small problem that grows fast
On its own, a cable off is usually a straightforward repair. The trouble starts when the door keeps getting moved while it is out of balance.
The door goes crooked
With one side lifting and the other side not, the door twists in the opening. The low side drags, and the high side pulls against the track.
The rollers start coming out
Rollers are made to ride straight up and down in the track. When the door is twisted, they get pulled sideways. Push or pull on the door enough and they pop out, one after another. In our video, more than half of them came out.
The door can fall out of the opening
Once enough rollers are out, the tracks are not really holding the door anymore. That is what we found on this job: the door was falling out of the opening. At that point it is not just a repair problem. It is a safety problem.
A garage door is heavy
A garage door is one of the heaviest moving things in your house. A door that is out of its track can shift or drop without much warning, and it does not care who or what is underneath it. That is why we tell people to stop and leave it alone.
Common reasons a garage door cable comes off
We cannot tell you exactly why a cable came off without looking at the door, but these are the usual suspects we check:
- Something in the way when the door closed. If the door comes down on a trash can, a bike or a car bumper, the cable on that side can go slack and jump off the drum.
- A spring that has broken or lost tension. When the spring is not holding tension right, the cable can loosen up and unwind off the drum. If you hear a loud bang in the garage, a broken spring is a good bet. More on that on our garage door spring repair page.
- A worn or frayed cable. Cables wear over time, especially near the bottom bracket. A frayed cable can stretch, slip or snap.
- Bent or loose track. If a track gets bumped or the brackets work loose, the door can bind on one side and throw off the cable.
- Opener problems or settings. An opener that keeps pushing or pulling when the door is binding can make a small problem much worse. If you think the opener is part of it, see our garage door opener repair page.
- Someone forcing the door. Like in our video, trying to muscle a crooked door up or down is one of the fastest ways to turn a cable off into a door off track.
Signs your cable is off (or about to be)
- One side of the door sits lower than the other when it is closed or partway open
- A cable hanging loose near the track or off the drum at the top
- The door jerks, shakes or stops partway
- Rollers that look like they are riding on the edge of the track, or are out of it
- A big gap at the bottom on one side when the door is closed
- Frayed or rusty strands on a cable near the bottom corners
If you see any of these, stop running the door and give us a call before it gets worse.
DIY vs. calling a pro
I get it. A lot of homeowners are handy, and a loose cable looks like it should be simple to put back. Here is the honest answer.
What is fine for a homeowner to do
- Stop using the door and the opener
- Look the door over from a safe spot and take a few photos to send us
- Clear the area around the door and keep everyone out from under it
- Keep up with normal care: keep the tracks clear of debris and watch for frayed cables or a door that looks uneven
What to leave to us
- Putting a cable back on the drum. The cable is tied to the spring system, and that system holds a lot of stored energy. Doing this wrong can hurt you.
- Anything involving the springs. Adjusting, winding or unwinding torsion springs is not a DIY job.
- Getting rollers back in the track. With a crooked, heavy door, this has to be done in the right order or the door can come down.
- Forcing the door in any direction. This is the big one. The customer in our video was trying to fix it himself, and each time he forced it, it got worse.
A simple fix stays simple when nobody forces it. The longer a crooked door keeps getting pushed around, the more there is to fix.
How we fix a cable-off, off-track door
Every door is a little different, but here is the general approach our techs take:
- Secure the door first. Before anything else, we make sure the door is not going to shift or drop while we work on it.
- Look at the whole system. Cables, drums, springs, rollers, tracks, hinges and the opener. We want to know why the cable came off, not just put it back.
- Get the door back in the track. We work the rollers back into the tracks and get the door sitting straight in the opening.
- Get the cables right. We get both cables back where they belong, and replace a cable if it is worn or damaged. See our garage door cable repair page for more.
- Check the balance and test it. We run the door, watch both sides, and make sure it opens and closes level.
On the job in the video, we got the door back in the track and now it closes level. That is the goal every time: a door that moves evenly on both sides and sits right in the opening.
How to keep a cable from coming off again
- Keep the area under the door clear before you close it
- Do not run the opener if the door looks uneven or sounds wrong
- Look at the cables near the bottom corners now and then for fraying or rust
- Listen for new grinding, popping or banging sounds
- Have the door looked over by a pro if it has been a while, especially if the springs are original
Our garage door repair in Houston page covers the other problems we see most often, from springs to openers to doors off track.
If the power goes out and your door is working normally, our guide to manually releasing and reengaging your garage door walks you through it. Do not use the release on a door that is off track or has a cable off. Leave that one to us.
Frequently asked questions
Can I still use my garage door if a cable came off?
No. Stop using the opener and do not move the door by hand. Running a door with a cable off can pull rollers out of the track and make the door fall out of the opening, like the one in our video.
Is a cable-off garage door dangerous?
It can be. A garage door is heavy, and when one side is not being held up, the door can shift or drop. Keep people, pets and cars out from under it until it is fixed.
Can I put the cable back on the drum myself?
We do not recommend it. The cables work with the springs, which hold a lot of stored energy. Putting a cable back the wrong way, or forcing the door to do it, can hurt you and damage the door.
Why is my garage door crooked?
A crooked door usually means one side is not being lifted the same as the other. A cable off, a broken spring, or a door binding in the track are common reasons. Stop using it and have it checked.
My rollers came out of the track. Can the door be saved?
In a lot of cases, yes. On the job in our video, more than half the rollers were out and the door was falling out of the opening, and we got it back in the track so it closes level. We will tell you honestly what we find once we see it.
Should I keep pressing the remote to see if it fixes itself?
No. A cable that is off will not fix itself, and every run can make things worse. Leave the door where it is and call us.
