What garage door cables do
The lift cables work with your springs to raise and lower the door's weight in a controlled way. When a cable frays or snaps — usually from rust, wear, or a spring failure — one side of the door can drop, jam, or hang crooked. It's a common companion to a broken spring.
Is the door safe to use?
No. With a broken cable the door's weight isn't properly supported, so it can slam down or come further off track. Don't run the opener. If the door is open, keep people and cars from underneath it until it's repaired.
Why cable replacement is a pro job
Cables run right next to high-tension springs, which can cause serious injury if handled wrong. We replace cables in matched pairs, inspect the springs and rollers at the same time, and re-balance the door. Most cable repairs are same-day — see garage door repair or call us.
Frequently Asked Questions
Should I replace one cable or both?
Both. Cables wear at the same rate, so replacing them in a matched pair prevents a second failure soon after.
Can a broken cable damage anything else?
Yes — running the door on a broken cable can bend track, damage panels, or strain the opener, so it's best to stop and call right away.
