Signs this system needs attention
- The door rises unevenly
- A cable is hanging beside the track
- Cable is tangled around a drum
- The bottom corner lifts before the other side
What the repair involves
The technician secures the door, checks the drums and bottom fixtures, replaces damaged cable where appropriate, restores equal cable tension and verifies that the door tracks evenly.
Lift cables connect the spring system to the bottom of the door. Wear often appears near the bottom bracket, where moisture can promote corrosion, or near the drum, where a cable that is not tracking correctly can fray against an edge.
A damaged cable can be the result of another fault rather than an isolated failure. Uneven spring tension, a cable that has left its drum, damaged travel hardware or a door that is no longer square can all load one side more heavily.
Both cables are inspected because they carry the same door and work through the same cycles. The door must be secured before cable tension or bottom hardware is touched.
Safety first
Do not remove a bottom bracket or cable while the spring system is under tension. The bottom fixtures are load-bearing parts.
