Garage Door Cable Snapped or Frayed
in Columbus, GA
Garage door cables are steel wire ropes that run along both sides of the door and connect to the springs. They carry a lot of tension, and when one snaps, the door goes crooked and becomes dangerous fast. Columbus humidity corrodes these cables from the inside out, which means the first sign of a problem is often the cable failing without much warning. Homes in areas like South Columbus near the Fort Moore corridor have a high number of older garage doors where this kind of cable wear has gone unnoticed for years.
Quick Answer
Garage door cables work with the springs to hold the door's weight and keep it moving evenly. When a cable snaps or unravels, one side of the door loses support and can drop suddenly. In Columbus, rust from year-round humidity eats through cable strands faster than in drier climates. Stop using the door immediately and call for service. A door with a broken cable can fall.
Telltale Signs
Warning Signs to Watch For
- The door hangs at an angle with one side lower than the other
- You see a steel cable lying loose on the garage floor or hanging off the drum
- The door makes a loud bang and then won't move
- The opener strains and the door moves only a few inches before stopping
- You can see fraying or broken strands on the cable when you look closely
- The door moves unevenly, jerking on one side during travel
Root Causes
What Causes Garage Door Cable Snapped or Frayed?
Rust and Corrosion on Cable
Columbus gets humidity levels above 70 percent for much of the year. That moisture works into the braided steel strands of the cable, causes rust, and weakens individual wires until the whole cable snaps under the load. Cables on the bottom of the door are the most exposed to water splash from rain.
The Fix
Cable Replacement
Both cables are replaced at the same time, not just the broken one. Replacing only one leaves a worn cable in place that is likely to fail soon. The drums and bottom brackets are inspected for damage caused by the failed cable.
Cable Drum Misalignment
The drum is the spool at the top of each side of the door that the cable wraps around. If a drum slips or is installed off-center, the cable wraps unevenly, which creates pressure at one spot and wears through the cable strands at that point. This happens more often when springs have been replaced without a full cable check.
The Fix
Drum Realignment and Cable Replacement
The drum is repositioned to the correct angle on the torsion bar, and new cables are wound onto it properly. The spring tension is also verified because an unbalanced spring setup is usually what caused the drum to shift in the first place.
Broken Spring Overloading Cable
When a torsion spring breaks, the full weight of the door transfers to the cables instantly. Cables aren't built to hold the entire door load on their own, and they snap or pull off the bottom bracket under that sudden weight. This is why a spring failure and a cable failure often happen together or close together in time.
The Fix
Spring and Cable Replacement Together
Both the broken spring and the damaged cable are replaced in the same visit. Fixing one without the other leaves the system unbalanced and increases the chance of another failure within weeks.
