If a cable is loose or snapped: stop using the door, don't run the opener, and don't pull the emergency release if the door is open. Keep everyone out from under it. Cables work under spring tension, and a door with a failed cable can hang crooked, jam, or drop.
What a snapped or loose cable looks like
From a safe distance, look for:
- A cable hanging loose at a bottom corner of the door
- A cable off its drum at the top of the door on either side
- One side of the door lower than the other, or the door hanging crooked
- The door jamming partway or coming off track on one side
- Frayed, rusty, or kinked cable you can see without touching it
- A snapping sound followed by the door stopping or dropping on one side
Why garage door cables fail
Lift cables run from the bottom corners of the door up to the spring system. They do the actual lifting. Common causes:
- Age and wear. Cables fray over thousands of open-close cycles.
- Rust and moisture. Damp garages speed up corrosion. Angi's Raleigh guides note that local humidity is hard on garage door parts.
- Spring problems. When a spring breaks or loses tension, a cable can go slack and jump off its drum. Broken spring repair
- Off-track doors. A twisted door can pull a cable out of place. Off-track repair
- Damaged drums or pulleys. A worn drum or bad pulley can chew through a cable.
A broken cable is often a symptom, not the whole story. A good technician will check the springs, drums, track, rollers, and bottom brackets in the same visit.
Why you shouldn't rewind the cable yourself
On torsion systems, the cables wrap around drums on the spring shaft above the door. On extension systems, they run through pulleys connected to the springs. Either way, the cables hold the door against the springs' stored energy.
Angi's cable repair guide describes the parts that hold the door in place as being under "a tremendous amount of pressure," and says an unexpected release can cause severe injuries. That's why we don't publish step-by-step cable instructions, and why Angi's guide says this is not an acceptable DIY project.
Leave springs, cables, drums, and bottom brackets alone.
What to do right now
- Stop using the door and don't press the opener.
- Keep people, pets, and cars clear of the door's path. Don't walk or park under an open or crooked door.
- Unplug the opener if you can reach the plug safely, so nobody triggers it by accident.
- Lock the door between the garage and the house if the garage door is stuck open.
- Take a photo from a safe distance of the bottom corners and the drums at the top, then request help.
- If your car is trapped, say so and choose "ASAP." Don't try to lift the door or re-seat the cable to get the car out.

Should both cables be replaced?
If one cable failed from age, the other has the same miles on it. Angi's cable guide recommends replacing both as good practice for safety and cost. New cables add little once the technician is already there with the tools and labor.

Frequently asked questions
My garage door cable came off one side. Can I put it back on?
Please don't. Re-seating a cable means working with the spring system under tension and a door that may be unbalanced. Angi's cable repair guide says cable repair is not an acceptable DIY project for that reason.
Should both garage door cables be replaced?
Angi's cable guide calls replacing both cables good practice for safety and cost. The second cable has the same age and wear, and new cables add little to the labor that's already happening.
How much does garage door cable repair cost?
Angi's national cable repair guide (updated July 2026) puts the average at $225, with a typical range of $100–$350. Re-seating a misaligned cable runs about $75–$200 per cable, according to the same guide. Extra parts or after-hours visits cost more.
