Garage door cable, roller and track repair

Signs of a cable or track problem

• One side of the door is higher than the other
• A cable is loose, frayed, or hanging off its drum
• Rollers have popped out of the track
• The track is bent, often after someone backs into it
• Grinding, scraping, or popping as the door moves
• The door stops and won't go further in one direction

Lift cables run from the bottom of the door up to drums on the spring shaft. Rollers ride inside the track on both sides.

What can be fixed

Lift cables

Cables fray at the bottom bracket where moisture collects. Techs replace both at once so they wear evenly.

Rollers

Old steel rollers wear flat and get loud. Sealed nylon rollers are quieter and are often rated for far more cycles.

Hinges and brackets

Cracked hinges between panels let the door flex and bind. They're inexpensive to replace during the same visit.

Tracks

Small dents can be straightened. A badly bent track section needs replacing so the rollers run smoothly again.

A door that's off its track or hanging by one cable can drop without warning. Leave it closed if possible, unplug the opener, and keep children and pets away until a tech arrives.

Questions about cables and tracks

Can I still use my garage door if a cable snapped?

No. With one cable gone, the door lifts unevenly and can jam or fall out of the track. Leave it where it is and keep people and cars clear.

How do I get my garage door back on track?

This is a job for a technician. Getting rollers back in the track usually means releasing spring tension and re-hanging cables, which is where injuries happen.

Why is my garage door so loud?

Worn metal rollers, dry hinges, and loose track bolts cause most of the noise. Nylon rollers with sealed bearings are much quieter and last far longer.
