Garage door cable came off?
If a lift cable is loose, off the drum, frayed, or broken, stop operating the door and keep clear. The door may be unsupported or uneven, and connected components can retain stored energy.

Possible Causes
- 01 Cable wear, corrosion, abrasion, or incorrect winding
- 02 Spring failure shifted load and threw the cable off
- 03 Drum lock screw loosened from vibration
- 04 Misaligned or bent track let the roller pop out, taking the cable with it
- 05 Vehicle impact bent a bracket
Safe First Checks
Stick to what you can see and what your door’s own manual asks of an owner — nothing more. Do not adjust springs, cables, drums, brackets, force, travel, or an unstable door.
- Look from a distance: is the cable hanging loose, off its drum, or snapped clean through?
- Note whether the door is level without touching or attempting to move it
- Do not run the opener; continued movement may worsen damage or instability
When to Stop and Request Service
This one isn't a judgment call: a cable that came off may still be tied to a wound spring. Don't touch the cable, drum, or brackets, don't run the door, and keep people clear. Call — releasing that tension safely is exactly what the right tools are for.
Frequently Asked Questions
Can I put the cable back onto the drum?
Do not handle or reposition a lift cable. It may be connected to stored spring energy, and the door may be unsupported. Keep clear and request qualified assessment.
Should one or both cables be replaced?
Both sides get looked at, always — cables work as a pair, and the survivor has been carrying extra load. We also check the drums and springs they connect to, so the repair holds instead of repeating.
