The remaining cable and the springs still hold tension that can whip a loose line or drop your door. Switch the opener off, keep people and cars out of the opening, and never touch the cable, the drum or the bottom bracket.

Broken Garage Door Cable in Carrollton, TX
Your garage door cable snapped or came off its drum: a steel line hangs loose beside your door, your door sits lopsided, or it slammed down with a bang. A broken garage door cable leaves one side without lift, so the full weight rides on the other cable and spring. Stop using your door, keep everyone clear of it, and call about your Carrollton garage before the second cable lets go.
What you are seeing
A lift cable hanging loose
Two lift cables run from the bottom corners of your door up to drums on the spring shaft. When one snaps or unwinds from its drum, that side of your door stops lifting with the other.
- Frayed strands
Broken wires along the line near the bottom bracket mark a cable close to failing.
- Cable off the drum
Slack, often after your door hit something on the way down, lets the line jump the drum's grooves.
- Rusted bottom bracket
Corrosion at the anchor point where the cable meets your door weakens its hold.
- Lopsided door
One side sits higher than the other, the clearest sign a lift line has failed.
Leave the cable, drum and bottom bracket alone, keep the opening clear, and call before the other side fails.
(972) 634-8789Safety protocol
Leave a door with a loose cable alone
Spring and cable tension is the most dangerous force on a garage door, and that work belongs with a trained garage door technician.
Loss risk
What a failed cable does next
Your door's weight shifts onto the one cable still holding, and every lift after that pulls at an angle.
- Second cable failure
The remaining line carries double its load until its strands part too.
- Door off level
Your door rises at a tilt, wedging one corner against the jamb.
- Bent bottom section
The bottom panel twists where the snapped line used to hold it.
- Falling door
With no lift line on one side, your door can slam down the moment the opener releases it.
Repair scope
What garage door cable repair covers
Professional cable work treats both sides, because a cable that failed on one side means the other has seen the same wear.
- Tension secured
Spring tension comes off safely before any cable work begins.
- New lift cables
Both lines come off and a matched pair of galvanized steel cables goes on, sized to your door's weight.
- Drums and brackets
Worn drum grooves or a rusted bottom bracket change out with the cables.
- Even wraps
Each line winds into the drum grooves with equal length, so both sides lift together.
Service sequence
From a hanging cable to a level door
Opener off
You stop using your door and keep the opening clear.
Weight supported
Your door stays held at the floor while spring tension comes off.

A matched pair of cables goes on, anchored at both bottom brackets.

Spring tension returns, sized to your door's weight.
Level lift
Your door rises and lowers level, with even wraps on each drum.
Local detail
When the door slammed shut
A bang from the garage followed by a door sitting crooked at the floor usually means a lift line let go on the way down. Leave your door where it landed in your Carrollton garage, keep the car out of the opening, and call.
Triage order
Why one broken cable is the time to call
A single snapped cable is a contained repair; two snapped lines, a bent bottom section and a door wedged at a tilt make a much larger one.
Call from Carrollton or elsewhere in Dallas County while your door still sits where the cable left it.

Common questions
Garage door cable questions from Carrollton
Can a garage door run on one cable?
No. Your door lifts at an angle, the single cable carries double the load, and your door can drop when that line fails.
Is a frayed cable worth calling about before it snaps?
Yes. Broken strands mean the line already lost strength, and renewing a frayed pair is simpler than repairing a door that fell when one parted.
Why replace both cables when only one broke?
Both lines carry the same load through the same cycles, so the unbroken one has the same wear. A matched pair also keeps your door lifting level.
What does a cable off the drum look like?
The line hangs slack beside your door or bunches at the shaft instead of sitting in neat wraps in the drum's grooves, and your door usually sits tilted.
A door held by a broken spring is a door waiting to drop.
Call from Carrollton before a broken spring or cable strips the opener or bends the sections.
