Garage door cables work with the springs to lift and lower the door, and a frayed or snapped cable is not a repair to attempt yourself. If your door hangs crooked, one side drops faster than the other, or you can see frayed strands at the drum, stop using the door and call for service.
Signs Your Cables Need Attention
- The door hangs unevenly or looks crooked when open or closed.
- Visible fraying, kinks, or rust on the cable.
- Slack in the cable instead of it staying taut.
- A sudden loud noise, which can mean a cable snapped.
- The cable has come off the drum at the top of the track.
Why This Isn't a DIY Repair
Cables stay under tension from the springs whenever the door is closed. Replacing or re-seating one means safely controlling that tension first, the same skill and tools a full spring job requires. A cable that's handled while still under tension can snap back suddenly.
What You Can Safely Do
- Look at the cables and drums from the floor without touching them.
- Stop using the opener if the door is hanging crooked or off-kilter.
- Keep people and vehicles clear of the door.
- Call and describe what you see, frayed strands, slack, or a cable off the drum.
What a Repair Visit Involves
We release the spring tension safely, inspect both cables and the drums they wind on, and replace whatever has failed. Cables typically get replaced in pairs, since both carry the same load and wear at a similar rate. We confirm the door is balanced and moving evenly before we finish.
FAQ
Can I repair a garage door cable myself?
We don't recommend it. Cables stay under spring tension whenever the door is closed, and handling one without releasing that tension safely first can cause injury.
How long do garage door cables last?
There is no dependable calendar interval. Use, moisture, abrasion and drum condition affect wear; replace frayed, corroded or damaged cables promptly after inspection.
Can I replace just one cable?
It's possible, but we usually recommend replacing both, since they carry the same load and tend to wear out around the same time.
What's the difference between cable repair and replacement?
Repair covers re-seating a cable that slipped off a drum or replacing hardware around it. See our cable replacement guide for what full replacement involves.
