Safe checks
Keep people clear
Stay out from under the door and keep vehicles out of the doorway.
Do not touch the bottom brackets
The cable attaches to brackets at the bottom of the door that are under high tension. Loosening them can cause serious injury.
Springs and cables are dangerous
Garage door springs and cables hold enormous tension and can cause serious injury. Never adjust, loosen or remove springs, cables or bottom brackets yourself. Only pull the emergency release when the door is fully closed: releasing a raised door with a broken spring can make it fall. Keep children and pets away from a damaged door.
Common causes
Cable off the drum
If the door closes on an obstruction or goes slack, the cable can unwind from the drum on the spring bar.
Frayed or rusted cable
Cables wear and rust over time, especially near the bottom brackets in damp garages. Frayed strands mean the cable is near failure.
Snapped cable
A broken cable usually leaves one side of the door lower than the other. The door can bind or fall.
Spring failure
A broken spring often causes cable problems too. See spring repair.
What to have ready when you call

- Whether the door is crooked, stuck or closed
- Whether you can see a loose, frayed or broken cable
- Whether you heard a loud bang
- Whether a vehicle is trapped
How garage door cable repair usually works
- Secure the door. The door is clamped so it cannot move while tension is released.
- Release tension safely. The technician unwinds the springs with proper tools before touching the cables.
- Replace cables. Both cables are usually replaced together so they match in length and wear.
- Rebalance and test. The door is leveled, the springs are retensioned and the opener and safety reverse are tested.
If a cable came off because the door hit something, the technician may also check the tracks, rollers and drums for damage.

Call 833-877-1717Garage door cable loose questions
Can a garage door cable be replaced alone?
Technicians usually replace both cables at once so they wear evenly, and check the springs and drums at the same time.
Why did my cable come off?
Common reasons are an obstruction under the door, a broken spring, worn drums or a door that went slack.
Is a frayed cable dangerous?
Yes. A frayed cable can snap and let the door drop. Stop using the door and have it inspected.
Can I call at night or on a weekend?
Yes. You can call 833-877-1717 at any time, including nights, weekends and holidays. Whether an independent provider can come out right away depends on your ZIP code, the time and provider capacity, so availability is not guaranteed.
