Garage Door Problems
A garage door cable came off the drum or hangs loose.
One lift cable may hang beside the track, coil loosely near the top drum, or lose tension while the opposite side stays tight. The door may stop crooked, wedge in the opening, or sit on the floor with slack cable visible on one side.

What you're seeing
Why it happens
A cable can leave its drum after the door is lifted unevenly, a spring loses tension, a cable frays or stretches, a drum shifts, a bottom fixture is damaged, or the door hits an obstruction and the cable unloads. Putting the cable back without correcting the reason it unloaded usually recreates the problem.
Homeowner checks
What you can check safely
- Stop the door and keep everyone clear of the opening.
- Photograph both drums, both cables, and the door position from a safe distance; this helps preserve the failure pattern before anything moves.
- Disconnect power to prevent accidental opener activation, but do not pull the manual release if the door is hanging or crooked.
- Look for frayed strands, rust, a shifted drum, or a bent bottom bracket without touching them.
Is it safe to keep using the door?
Do not grab, cut, wind, or pull a loose cable. Do not loosen the bottom bracket or cable drum set screws. Spring torque can remain in the system and can move hardware suddenly. A crooked door can also drop or leave the track when its restraint changes.
What the fix involves
The repair secures the door, removes spring tension in a controlled way, inspects both cables and drums, corrects the underlying spring, alignment, obstruction, or hardware problem, and installs matched cables if wear is present. The cables are then set evenly and the door is balanced through full manual travel before the opener runs it.
This is handled by our Springs, Cables & Tracks service across Connecticut. Call to check current availability.
Quick answers
Can the same cable simply be put back on the drum?
Only after it is inspected and the reason it came off is corrected. A kinked, frayed, rusted, or stretched cable should not be reused, and the opposite cable needs inspection too.
Why is the door crooked when a cable comes off?
Each cable lifts one side. If one loses tension while the other continues to pull, the door racks in the opening and can bind its rollers in the tracks.
Should I pull the emergency release?
Not while the door is crooked, hanging, or partly open. Disconnecting the opener can remove one restraint and allow an unstable door to move unexpectedly.

The cable on the floor is the visible failure; equal lift on both sides is the real repair.
