Snapped or Frayed Cable? Stop Immediately.
Expert Cable Replacement to Restore the Safety and Balance of Your Door.
The Lifelines of Your Garage Door
The Critical Role of Your Garage Door Cables
While your garage door springs provide the raw power, the high-tension steel cables are the critical lifelines that transfer that energy to lift the door’s immense weight. Working in perfect sync with the drums and springs, these cables bear hundreds of pounds of force with every cycle. When a cable becomes frayed, worn, or snaps, the entire system is dangerously compromised, becoming unbalanced and unpredictable.
Symptoms of a Failing or Broken Cable
- A Slanted or Crooked Door: A broken cable on one side will cause the door to hang unevenly and often become jammed in the tracks.
- Visible Fraying or Corrosion: You can see broken steel strands or significant rust on the cable, usually near the bottom brackets or the top drums.
- Sudden, Loud Noise Followed by a Crash: If a cable snaps during operation, the door can suddenly fall on one side, creating a loud and dangerous impact.
- Cable Slipped Off the Drum: You might see a loose, spaghetti-like cable hanging or notice it has come unwound from the grooved drum at the top of the door.
DANGER: Cable Replacement Requires Professional Expertise
Garage door cables are directly connected to the high-tension spring system. Attempting to replace a cable without properly securing the door and completely releasing all spring tension can cause the spring to unwind violently, resulting in severe injury. This is not a simple fix; it is a hazardous procedure that requires specialized knowledge, tools, and a deep understanding of the door’s mechanics to perform safely.
Frequently Asked Cable Questions
Yes, always. Cables are installed in pairs and are exposed to the exact same amount of wear and tear. If one has failed, the other is significantly weakened and likely near the end of its service life. Replacing both ensures the door remains perfectly balanced and saves you from a second, inevitable repair call.
The most common causes are natural wear and tear over thousands of cycles, corrosion from moisture (especially at the bottom of the door), or fraying from rubbing against a misaligned track. An improperly balanced spring can also put extra stress on the cables, leading to premature failure.
Yes. A frayed cable is a snapped cable waiting to happen. The integrity of the cable is compromised, and it can fail without warning. If you see any signs of fraying, stop using the door immediately and call us to prevent a more dangerous and damaging failure.
