Garage Door Cables Broken or Frayed
in Grand Rapids, MI
Cables are the steel wire ropes that connect the bottom of the door to the spring system. They keep the door moving evenly on both sides. In Grand Rapids, the road salt and moisture that come with lake-effect snow winters corrode the steel wires, causing the cables to fray from the inside out before you can see the damage on the surface.
Quick Answer
Garage door cables carry the weight of the door alongside the springs. When a cable frays or snaps, the door can drop suddenly on one side or fall completely. In Grand Rapids, road salt and garage moisture corrode cables faster than in drier climates. A technician replaces both cables at the same time. Do not try to run the door with a broken cable.
Telltale Signs
Warning Signs to Watch For
- One side of the door is lower than the other
- A cable is visibly hanging loose on one side of the door
- The door dropped suddenly while closing
- You can see frayed or unraveling wire strands on the cable
- The door shudders or jerks while moving
Root Causes
What Causes Garage Door Cables Broken or Frayed?
Cable Corrosion from Salt and Moisture
Grand Rapids winters mean vehicles bring road salt into the garage every day from November through March. Salt and damp air corrode the small steel wires inside the cable, weakening them strand by strand until the cable snaps under load.
The Fix
Cable Replacement with Corrosion-Resistant Cable
A technician replaces both cables even if only one has broken. Galvanized or coated cables resist rust better and last longer in a salty, wet environment.
Cable Drum Misalignment
Cables wrap around drums at the top of the door. If a drum works loose or spins off-center, the cable wraps unevenly and frays against the drum edge. This happens on doors that have gone years without any maintenance.
The Fix
Drum Realignment and Cable Replacement
A technician secures the drum in the correct position and replaces the frayed cable. The spring tension is checked at the same time because a misaligned drum is often a sign the whole system is off-balance.
Spring Failure Causing Cable Snap
When a spring breaks, all the weight of the door shifts suddenly onto the cables. A 200-pound door dropping its full weight onto a cable in an instant is more than most cables can handle, and they snap or slip off the drum.
The Fix
Spring and Cable Replacement
A technician replaces both the broken spring and the damaged cable together. Fixing one without the other leaves the repaired part under more stress than it should carry.
