Cable Replacement · Utah County
Two thin cables carry the entire door.
On a torsion spring door, a steel cable runs from a bracket at the bottom corner of the door up to a grooved drum on the shaft above the opening. As the spring unwinds, the drum takes up the cable and lifts that side of the door. There's one cable per side and that's the whole lifting system. Everything the springs do reaches the door through those two cables.
Cables fail for reasons you can usually see once you know where to look. Corrosion at the bottom is the most common one in Utah, because the bottom bracket sits at floor level where snowmelt, road salt and standing water collect off the car. The strands rust from the inside, the cable loses strength, and it lets go at the fitting. Misalignment is the second cause. If a drum is out of position or the cable isn't spooling into its grooves cleanly, the cable rubs against itself or the drum flange and abrades. The third is slack. If the door closes onto an obstruction, or onto an uneven floor, the drum keeps turning while the door has stopped, the cable goes loose, and it jumps off the drum.
You get a warning if you look. A failing cable frays first, and a frayed cable has broken strands standing out of the lay like whiskers. Run a flashlight along both cables, top to bottom, with the door closed. Look particularly at the last foot above the bottom bracket and at the point where the cable wraps the drum. Any broken strands, kinks, flat spots or rust means the cable is on borrowed time.
When one does snap, the failure is immediate and lopsided. That side drops, the door goes out of square, the rollers come out of the track and the whole thing jams in the opening. That's why a cable call and an off track call are so often the same call. It's also why cables are replaced in pairs. The second cable is the same age, has taken the same number of cycles and has lived in the same wet corner of the garage.
The bottom bracket that the cable attaches to is under full spring tension even with the door closed and the opener unplugged. That's the reason cable work isn't a homeowner job. The tension has to be released and controlled before that bracket is touched.
Before you call · Cable Replacement
Signs a cable is going or gone
- Visible broken strands, kinks or rust, especially near the bottom bracket
- One cable hanging loose while the other is tight
- The door opens or closes crooked, one side leading the other
- The cable has jumped off the drum and is bunched up on the shaft
- A scraping or snapping noise partway through travel
- The door drops on one side and jams in the opening
- Slack cable every time the door reaches the floor
Worth knowing before you call
- Don't run the opener once a cable has failed. The remaining cable is carrying a load it wasn't designed to carry alone
- The bottom brackets stay under full spring tension with the door closed. They are not a bolt to loosen and see what happens
- If the floor is uneven or something is regularly left in the doorway, the new cable will go slack too. Fixing the cause is part of the repair
Why this job goes to Clark
Get both sides lifting evenly again.
Always in pairs
The second cable has the same age, the same cycle count and the same exposure to water on the floor. Replacing one is a half repair.
The drums get checked
A cable that frays in one spot is usually telling you something about the drum it wraps. Grooves, set screws and drum position all get looked at.
Caught early is a small job
A frayed cable spotted during a tune up is a straightforward replacement. A snapped one usually brings bent track and damaged hinges with it.
Questions · Utah County
Cable Replacement FAQ
How do I know if my cables are worn?
Close the door, unplug the opener and take a flashlight down both cables. Broken strands sticking out of the twist, kinks, flattened spots and rust are all reasons to replace. The two places to look hardest are the last foot above the bottom bracket and where the cable winds onto the drum.
Why do the cables rust at the bottom?
Because that's where the water is. Snow comes off the car, melts on the floor and pools at the door line, and road salt comes with it. The bottom bracket and the last stretch of cable sit right in it, so that's where corrosion starts.
One cable broke. Does the other one need doing?
Yes. Same age, same cycles, same wet corner. Replacing only the failed cable leaves a mismatched pair and the door will be back to uneven travel and another failure before long.
Can I just push the cable back onto the drum?
No. Reseating a cable means controlling the spring tension first, then winding both drums so each side takes up exactly the same length. Get that uneven and the door runs out of square and comes off the track again.
What customers say
Clark was fantastic! My garage door cable had come off the spool, leaving the door unable open or close on its own. Not only did he fix the cable, but he also took the extra time to even out the garage door and adjust the track so everything operated smoothly. He answered all my questions, and explained what would need to be done to fix it. Clark was friendly, and incredibly thorough.
