Garage Door Cables Snapped or Fraying
in Albuquerque, NM
Garage door cables are steel wires that work with the springs to lift and lower the door evenly. In Albuquerque, the combination of summer monsoon moisture and very dry winters causes these cables to fray at the ends where they wrap around drums at the top of the door. A broken cable on one side causes the door to drop at an angle, which can damage the door, the tracks, and anything underneath.
Quick Answer
Lift cables run along each side of your garage door and help the springs carry the door's weight. In Albuquerque, rust from monsoon season humidity and dry-air fatigue from the rest of the year work together to fray those cables faster than you'd expect. A snapped cable can drop one side of the door suddenly. Call someone before you use the door again, because a cable under tension can cause serious injury.
Telltale Signs
Warning Signs to Watch For
- One side of the door is lower than the other when opening or closing
- You can see individual wire strands sticking out from the cable
- The door jerks or lunges to one side when it moves
- The cable has come off the drum at the top corner of the door
- The door came down hard and fast on one side without warning
Root Causes
What Causes Garage Door Cables Snapped or Fraying?
Rust and Corrosion at Cable Ends
The ends of the cables sit in metal ferrules and wrap around steel drums, two places where moisture sits after Albuquerque's monsoon rains. That trapped moisture rusts the cable from the inside out, and the individual wires break one at a time until the cable snaps.
The Fix
Cable Replacement with Corrosion-Resistant Cable
A technician releases the spring tension safely before touching the cables, then removes both cables and fits new galvanized or coated steel cables. Both sides get replaced even if only one snapped, because the other is usually just as corroded.
Cable Drum Misalignment
If the drum at the top of the door shifts out of position, the cable wraps unevenly and starts to fray where it bunches up. This often happens on doors in homes built in the 1980s in the North Valley, where original hardware has never been adjusted and has shifted slowly over 30 or 40 years.
The Fix
Drum Realignment and Cable Replacement
A technician resets the drum to its proper position on the torsion bar and then installs a new cable. If the drum itself is cracked or warped, it gets replaced before the new cable goes on.
Spring Failure Overloading the Cable
When a spring breaks, the full weight of the door shifts onto the cables instantly. Cables are not designed to carry that load alone, and the sudden stress snaps or badly frays them in the same event that breaks the spring.
The Fix
Combined Spring and Cable Replacement
A technician replaces the broken spring and both cables in the same visit. Doing them together makes sense because the labor to access both is nearly the same, and the cables are already stressed.
