How a Cable Comes Off the Drum
The lifting cables on a garage door wind around grooved drums attached to the torsion spring shaft. When everything is aligned, the cable stays seated in its groove as the door opens and closes. If the drum shifts, a roller binds, or the cable frays and loses tension, the cable can slip out of its groove and bunch up or hang loose on one side of the door.
This often shows up as a door that tilts to one side, stops partway, or makes a grinding or popping noise as it moves. Because the door is still under spring tension even when the cable is off, attempting to force it back into place without the right tools and technique can be dangerous.
Common Reasons a Cable Slips Off the Drum
Several everyday issues can cause a cable to jump its track over time.
Rollers that no longer sit flush in the track can pull the door and cable out of alignment as it travels up and down.
If a drum works loose on the shaft, its grooves no longer line up with the cable, which can let it slip free.
A cable that has thinned, frayed, or stretched over years of use is more likely to jump the groove under tension.
When one torsion spring is more worn than the other, uneven pull on each side can push a cable off its drum.
A bump from a vehicle, a slammed door, or forcing a stuck door can knock a cable loose from its drum.

Stop Using The Door
Avoid using the automatic opener or forcing the door by hand once you notice it hanging unevenly or making unusual noises.
Check For Obvious Damage
Look for a visibly loose, bunched, or dangling cable on one side, but avoid touching springs, cables, or drums directly.
