What Garage Door Cables Do (And Why They Matter)
Garage door cables may look small, but they do some heavy lifting—literally. These cables work along with your door’s torsion or extension springs to lift and lower the door smoothly.
When one of these cables wears out or snaps, your door becomes unstable, or worse, it gets stuck. That’s not only frustrating but also dangerous. Ignoring a frayed or broken cable can cause the door to come crashing down or damage the track.
Knowing how to handle a garage door cable repair gives you an edge—and helps you avoid expensive service calls in the future.
Signs Your Garage Door Cable Is in Trouble
How do you know if your garage door cable is damaged or about to snap? Here are a few red flags:
- Your garage door looks crooked or off-balance.
- One side lifts while the other lags behind.
- You hear a loud snapping sound, and the door suddenly stops moving.
- The cable looks frayed, loose, or is completely detached.
If you spot any of these signs, don’t wait. Cable problems usually get worse fast, and they don’t fix themselves.
Safety First: What You Must Know Before Starting Repairs

- Use winding bars—never screwdrivers—to release spring tension.
- Wear gloves and safety glasses.

How to Fix a Garage Door Cable: Step-by-Step Instructions
Here’s where the rubber meets the road. Follow these clear, safe, and simple steps for a full DIY garage door cable repair:
Step 1: Keep the Door From Moving
Use vice grips or pliers to lock the door in place by clamping them just below the bottom roller on each side.
Step 2: Release Tension from the Springs
Use winding bars to carefully unwind the tension from the torsion springs. Never rush this step. Follow your manufacturer’s specs exactly.
Step 3: Remove the Old, Broken Cable
Detach the snapped garage door cable from the drum at the top and the bottom bracket. Toss it.
Step 4: Thread and Install the New Cable
Feed your new cable through the pulley system. Keep it aligned straight, without kinks or slack.
Step 5: Secure the Cable
Connect the cable to the bottom bracket, then wrap it around the drum at the top. Make sure it’s snug.
Step 6: Wind Up the Springs Again
Re-tension the torsion springs with winding bars. Count your turns and match the original setting to avoid imbalance.
Step 7: Test the Door
Remove the vice grips and manually lift the door to test smooth operation. It should open evenly, without hesitation or noise.

How to Prevent Future Cable Breaks
Here’s the thing—garage door cables don’t last forever. But with a little care, you can make them last a whole lot longer.
Keep Your Eyes on the Cables
Do a monthly checkup. Look for fraying, rust, or loosening. Catching small issues early = big savings.
Use the Right Lubricant
Spray a silicone-based lubricant on the cables, rollers, and tracks every few months. Don’t use WD-40—it attracts dirt.
Don’t Let the Door Slam
A garage door that crashes down puts extra strain on the cables. Adjust your springs if needed, or hire a pro.
