Cable Repair

Signs of cable wear include visible fraying, stretching that causes uneven door operation, unusual grinding noises, cables that appear thinner than normal, or doors that don't stay in position when partially opened. Regular inspection during maintenance visits can catch these issues early.

For safety and proper balance, both cables should typically be replaced together. Garage doors require balanced tension from both sides for safe, smooth operation. Even if only one cable appears damaged, replacing both ensures consistent performance and prevents future imbalance issues.

Cables should be visually inspected during annual maintenance, though replacement frequency depends on usage and environmental conditions. Heavy-use commercial doors may need replacement every 3-5 years, while residential doors typically last 7-10 years. Environmental factors like humidity and temperature extremes can accelerate wear.

Yes, cable issues can lead to imbalanced doors that cause excessive wear on rollers, tracks, and hinges. The uneven load can also strain springs and opener motors, potentially leading to more extensive and expensive repairs if not addressed promptly.

Aircraft cable (7x19 construction) is commonly used in garage doors and features multiple strands of wire for strength and flexibility. The numbers indicate the number of strands and wires per strand. Higher-quality cables have more wires per strand, providing better strength, flexibility, and resistance to fatigue.
