What Does a Garage Door Cable Do?

Garage door cables work together with a set of torsion springs to lift and lower your garage door. Your door has two cables that attach to the bottom edges and wrap around drums at the ends of the metal bar on your ceiling. As the spring unwinds, it turns the cable drums, which pull the cables and lift the door.

Cable Snapped? Here's Why

Garage door cables are exposed to humidity and moisture, which can cause them to rust and weaken over time. Also, as the door opens and closes, the moving parts can cause the cables to fray and break unexpectedly.

What Are the Warning Signs of a Failing or Broken Cable?

Cable failure isn't always obvious. For example, you may not always hear a loud noise when the garage door cable snaps. If you try to open the door and it won’t open, or it opens only a few inches before it stops, that’s a good sign of a broken cable. Examine the cables on the door. If it looks like a rope with frayed ends, it’s likely about to fail. Also, check the door tracks and rollers. If the wheels look like they're popping out of the track, the cable may have lost tension and can no longer hold the door in place.

Is It Safe to Operate a Garage Door With a Broken Cable?

Never open a garage door if you know the cable is broken. This is a major safety issue. Cable tension can cause the door to crash down unexpectedly, resulting in property damage or injury.

If the cable fails, it could also damage the garage door opener motor as it tries to compensate for the weight. When a cable snaps, the door is no longer balanced, so other parts, like the springs and the other cable, are under stress. Disconnect the opener or flip the breaker, then contact a professional for repairs.

Can Homeowners Safely Replace a Garage Door Cable Themselves?

Many online videos show how to replace a garage door cable. However, this task is best left to a professional. Changing cables requires specialized tools, such as winding bars, locking pliers and cable cutters. Because the cables are under tension, the wrong move could cause the doors to come crashing down. Sometimes, cables snap during installation, which can also cause injuries. Keep safety in mind. A licensed and insured garage door technician also has the experience and knowledge to manage the tension safely and ensure your door is perfectly balanced.
