If a cable just snapped: stop using the door, unplug the opener if you can reach it safely, and keep everyone out from under the door. Don't pull the red emergency release while the door is up. Then request help.
Garage doors have a lift cable on each side. The cables run from the bottom corners of the door up to the drums or pulleys of the spring system, and they're what actually lift the door. When one snaps or jumps off its drum, the door loses its balance on that side.
What to do in the next ten minutes
- Stop pressing the button. Running the opener against a door with a failed cable can twist the door, pull it off track, or damage the opener.
- Unplug the opener if you can reach the plug without standing under the door.
- Keep people, pets, and cars out of the door's path. Don't walk or park under an open or crooked door.
- Leave the emergency release alone if the door is open. The opener may be what's holding it up.
- Lock the door between the garage and the house if the garage door is stuck open.
- Take a photo from a safe distance of both bottom corners and the drums at the top of the door. It helps the company bring the right parts.
- Request help. Choose "ASAP" if a car is trapped or the door is stuck open overnight.
How to tell it's a cable (and not something else)
From a safe distance, look for:
- A cable hanging loose at a bottom corner, or coiled on the floor
- A cable off its drum at the top of the door
- The door sitting lower on one side, or jammed at an angle
- Frayed, rusty, or kinked cable on the side that's still attached
- A loud snap, then the door stopped or dropped on one side
A broken cable often travels with other damage. If you also see a gap in the spring above the door, see broken spring signs. If a roller has popped out of the track, see off-track repair. If the door stopped partway, read garage door stuck halfway.
Why it's not a DIY fix
Angi's cable repair guide says the parts that hold a garage door in place are under "a tremendous amount of pressure," that an unexpected release can cause severe injuries, and that cable repair is not an acceptable DIY project. On torsion systems, a broken or misaligned cable makes the door exceedingly heavy. On extension spring systems, Angi says a broken cable can let the spring contract rapidly and come loose.
Re-seating or replacing a cable means releasing and re-applying spring tension. That's why we don't publish step-by-step cable instructions. Leave springs, cables, drums, and bottom brackets to a technician.
Why Twin Cities cables fail
- Age and wear. Cables fray over thousands of open-and-close cycles.
- Road salt and moisture. Angi's Minneapolis repair guide says salt and sand from icy roads can corrode metal garage door parts faster. Salty slush dripping off cars sits right where the bottom brackets and lower cable ends are.
- Cold-weather strain. Angi's Minneapolis guide also notes that cold winters can freeze springs and stiffen tracks. A door that's frozen to the floor on one side and then forced up can put uneven load on a cable. See door frozen to the ground.
- Spring failure. When a spring breaks, a cable can go slack and jump off its drum.

What to tell the company
- Which side failed, and whether the door is level, crooked, open, or closed
- Whether you heard a bang (a spring) or a snap (a cable)
- Whether a car is trapped
- The photo of the bottom corners and drums
Ask for a written price before work starts, whether they'll replace one cable or both, and what the warranty covers.

Frequently asked questions
Can I still use my garage door with a snapped cable?
No. The lift cables connect the bottom of the door to the springs that balance it. With one cable gone, the door is unbalanced and can hang crooked, jam, or drop. Angi's cable repair guide says a broken cable usually leaves the door unusable and calls cable repair an unacceptable DIY project.
My car is trapped behind a door with a broken cable. What do I do?
Don't try to lift the door or pull the emergency release to get the car out. Angi's cable guide notes that even knowing how to open the door manually isn't likely to help because of the door's weight. Request help, choose "ASAP," and say a car is trapped.
How much does it cost to fix a snapped garage door cable?
Angi's national cable repair guide (updated July 2026) puts the average at $225, with a typical range of $100–$350. HomeGuide's cable guide (October 2025) lists replacing both cables at $150–$250 and emergency cable repair at $250–$350 or more. The company you're connected with sets its own price.
Should both cables be replaced if only one snapped?
Angi's cable guide calls replacing both cables good practice for safety and cost effectiveness. The other cable has the same age and wear, and a new pair costs little compared with the labor already involved.
