Crafted from sturdy metal, garage door cables are designed for strength. However, their flexibility, essential for traversing the pulley system or wrapping around drums, increases the likelihood of breakage. Wear and tear over time compromise their strength, leading to eventual breakage.

Regular checks on cable strength are crucial to spot signs of fraying promptly. Rust, another common culprit, can corrode cables, rendering the garage door dysfunctional. Unlevel doors signal potential cable issues, especially in torsion spring setups where cables may wrap around drums, causing movement interruptions. Reconnecting cables is hazardous due to the extreme tension in the spring.

For extension spring setups, inspecting pulleys is essential. Worn-out pulleys can disrupt cable movement, resulting in an uneven door or getting stuck. In such cases, pulley replacement may be necessary.
