Cable Failure in Los Angeles: Diagnosis, Repair, and Prevention

Lift cables work with the springs to move a door that may weigh several hundred pounds. A safe repair must address why the cable failed, not simply install a new wire rope.

Why Garage Door Cables Fail

Cable damage usually starts where the cable wraps around the drum or passes near the bottom bracket. Rust, a rough drum groove, a seized bearing, or a door that sits crooked can fray one strand at a time until the cable snaps. In coastal Los Angeles neighborhoods, humid salt air accelerates corrosion. In hotter inland valleys, dry rollers and repeated thermal expansion place extra side load on the cable. We inspect both cables, drums, bearings, bottom brackets, tracks, and spring balance so the replacement is not damaged by the same underlying problem.

Why We Usually Replace Cables as a Matched Pair

When one cable fails, the cable on the other side has completed the same number of cycles and has carried the same load. Replacing only the broken side can leave the door lifting unevenly because the older cable may be stretched or internally worn. A matched pair with the correct diameter, length, and construction keeps the door level and distributes load evenly. We also confirm that each cable seats correctly in its drum grooves before setting tension and testing the door by hand.

What a Complete Cable Repair Includes

The door is first secured so it cannot fall or shift. We release system tension using the correct tools, remove damaged cables, inspect the drums and attachment points, install door-rated replacements, and reset the counterbalance system. The final checks include manual balance, cable tracking through a full cycle, opener force, photo-eye reversal, and the condition of rollers and hinges. If a spring, drum, or track caused the failure, we explain that finding before additional work is performed.

What to Do While Waiting for Service

Keep the door fully closed if it is already down, move people and pets away, and do not pull the emergency release or attempt to lift the door. If the door is stuck open or hanging unevenly, do not stand beneath it or try to support it with household objects. A cable can still carry substantial tension even when it looks loose. Photograph the door from a safe distance and tell the technician whether you heard a snap, saw the door tilt, or noticed a cable hanging beside the track.
