How do I know if my garage door spring is broken?
The clearest signs of a broken garage door spring are a loud bang from the garage, a door that suddenly feels extremely heavy or will not lift at all, and a visible gap in the coiled spring above the door. A door with a broken spring is carrying its full weight and can fall, so it should not be operated.
Springs and cables are not a DIY job. A garage door spring stores enough energy to cause serious injury, and the cables and bottom brackets are under load whenever the door is not fully open.
Checking, cleaning and looking are safe. Adjusting, releasing or replacing anything under tension is not. Call (702) 454-3667.
What you will notice first
Most people hear it before they see it. A torsion spring failing makes a single loud bang, often mistaken for something falling over in the garage. If that happened and the door will not open afterwards, the spring is the first thing to suspect.
The next sign is weight. A balanced garage door feels almost weightless because the spring, not the opener, carries the load. When the spring goes, the door is suddenly a hundred and fifty pounds or more of steel, and an opener designed to guide it rather than lift it will strain, stop, or reverse.
Visually, look at the spring mounted on the bar above the door opening. A broken torsion spring shows a clear gap of an inch or two where it has separated. On older doors with extension springs running along the horizontal tracks, a failure usually looks like a spring hanging loose or stretched out of shape.
Why the door should not be used
Without the spring there is nothing counterbalancing the door. If it is part-way open and the opener releases it, or if someone pulls the emergency release, the door can come down under its own weight. Do not operate it, do not try to lift it by hand, and do not park under a partly open door while waiting for a repair.
This is also why a broken spring is not a DIY job. A torsion spring under load stores a large amount of energy, and releasing it without the correct winding bars is how people lose fingers. The tools are cheap; the failure mode is not.
What the repair involves
A technician measures the existing spring, confirms the door weight it was sized for, and fits a replacement rated for that weight. The door is then rebalanced so it holds position part-way open and the opener returns to guiding rather than lifting.
Springs are rated in cycles rather than years, so a technician will often look at the rest of the hardware at the same time: rollers, hinges, cables and the bottom brackets all age alongside the spring and are far cheaper to address while the door is already apart.
Common questions
Can I still open my garage door if the spring is broken?
You should not. The door is carrying its full weight, often over a hundred and fifty pounds, and it can fall. Lifting it by hand is how people are injured. Leave it where it is and call for service.
Should both springs be replaced if only one broke?
On a door with two springs, both have usually done the same number of cycles, so the second is generally close behind the first. A technician will advise based on the condition and age of the remaining spring. We do not quote spring work per spring until scope is confirmed on site.
How long does a spring replacement take?
Most spring work is finished within a single arrival window. Doors with unusual sizing, or where other hardware has failed at the same time, can take longer, and the technician will tell you before starting.
