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.
Signs of a cable problem
- A cable hanging loose at the bottom corner of the door or coming off the drum at the top
- One side of the door lower than the other, or the door hanging crooked
- The door jams partway or comes off track on one side
- Frayed, rusty, or kinked cable you can see from a distance
- A snapping sound followed by the door stopping or dropping on one side
Why garage door cables fail
- Age and wear. Cables fray with thousands of cycles.
- Rust and moisture. Humidity and damp garages speed up corrosion. Angi's Raleigh guides point out that the area's 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 up a cable.
Why cables aren't a DIY repair
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 on each side. 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.
Cables, drums, and springs: often a package
A broken cable is often a symptom, not the root cause. A good technician will check:
- The springs. Are they balanced and correctly tensioned?
- The drums and pulleys. Are they cracked, worn, or out of line?
- The track and rollers. Did the door twist or come off track?
- The bottom brackets. Are they rusted or bent where the cable attaches?
If one cable failed from age, ask about replacing both. Angi's cable guide recommends it.

Frequently asked questions
My cable came off. 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.
Why did my cable break on one side?
Cables wear, fray, and rust over time, and one side can simply go first. A cable can also come off its drum if the spring tension is wrong, the drum is damaged, the door came off track, or something obstructed it.
Should both 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 cost of labor that's already happening.
How much does garage door cable repair cost?
