Garage Door Parts FAQ
How do I know if my garage door cable is bad?
Signs of a damaged cable include a crooked door, loud snapping noise, loose hanging cable, or the door getting stuck halfway. A broken cable should be repaired immediately to prevent the door from falling off track.
Can I replace garage door rollers myself?
Garage door rollers are under spring tension and connected to moving tracks. Improper replacement can cause injury or door damage. Professional service is recommended for safe installation and proper alignment.
Why is my garage door loud when opening?
Noise is usually caused by worn rollers, loose hinges, dry bearings, or a failing opener gear. Replacing worn parts and lubricating moving components typically restores quiet operation.
What is the most common garage door part to break?
The most common garage door failure is a broken torsion spring. Springs carry the weight of the door and wear out over time from daily use. When a spring breaks, the door usually will not open.
What causes a garage door to go off track?
A garage door may go off track due to broken cables, bent tracks, worn rollers, or impact damage. Operating the door in this condition can cause further structural damage.
How long do garage door springs last?
Most garage door springs last about 7–12 years depending on usage. High-cycle springs may last longer with proper maintenance.
