Cable Snapped or Frayed
in Glendale, AZ
The lift cables on a garage door carry a significant load every time the door moves. They are under high tension even when the door is sitting closed. In Glendale, homes built in the 1980s and early 1990s often still have original cables that are past their service life. Heat and dryness cause the individual wire strands to fray and break one by one until the cable fails, sometimes all at once. A dropped door on one side puts dangerous strain on the spring system and the opener.
Quick Answer
Garage door cables are the steel wires that hold the door up when the springs do their job. When a cable snaps or frays badly, the door can drop suddenly on one side. This happens more often on Glendale homes built before 1995 where the original cables have never been replaced. Do not operate the door if a cable has snapped. Call (928) 404-0934 so a technician can replace the cable safely with the door secured.
Telltale Signs
Warning Signs to Watch For
- The door hangs lower on one side when closed
- You can see a frayed or kinked section of cable near the drum or bottom bracket
- One side of the door dropped suddenly while operating
- The door is stuck and the opener sounds strained when trying to move it
- There is a loose loop of cable visible on the garage floor or hanging off the drum
Root Causes
What Causes Cable Snapped or Frayed?
Age and Wire Strand Fatigue
Steel cables are made of many thin strands twisted together. Each strand flexes slightly every time the door moves, and after years of use, individual strands start to break. Glendale homes built in the early 1990s that have never had cable service are almost certainly running on cables that have broken strands you can't see from the outside.
The Fix
Cable Replacement
A technician releases the spring tension safely before removing the old cable, then installs a new cable of the correct diameter and length for your door. Both sides get replaced at the same time because a cable on one side is typically as old as the cable on the other.
Bottom Bracket Wear or Failure
The cable attaches at the bottom of the door on a bracket near the floor. If that bracket rusts, loosens, or cracks — which happens faster in garages that collect monsoon moisture and then dry out repeatedly — the cable slips off or the attachment point fails and the cable goes slack instantly.
The Fix
Bottom Bracket and Cable Replacement
A technician replaces the failed bracket and the cable together, since a cable that has been running on a bad bracket is likely kinked or damaged. The new bracket gets fastened to solid door material, not corroded metal.
