7 Signs Your Garage Door Spring Is Broken (And What to Do in Atlanta)

If your garage door suddenly feels impossibly heavy, stops halfway, or you heard a loud bang from the garage last night, you may have a broken spring. In Metro Atlanta, torsion and extension springs fail thousands of times a year — especially during temperature swings when metal expands and contracts.

Garage door springs counterbalance the full weight of your door — often 150 to 250 pounds. When they break, the opener alone cannot safely lift the door. Continuing to use a door with a broken spring can strip opener gears, bend tracks, or cause the door to fall unexpectedly.

1. You Heard a Loud Bang From the Garage

A snapping torsion spring releases stored energy instantly and often sounds like a gunshot or car backfire. Many Atlanta homeowners discover a broken spring this way — especially early in the morning when the door is first opened for the commute.

If you were not in the garage when it happened, look for a visible gap in the spring coil above the door. A intact torsion spring should have tight, even coils with no separation.

2. The Door Feels Extremely Heavy

Try lifting the door manually using the emergency release cord. If it takes significant force or will not budge, the spring is likely broken or out of balance. A properly balanced door should lift smoothly with moderate effort and stay open about three to four feet off the ground on its own.

3. The Door Only Opens a Few Inches

Modern openers have force limits. When a spring fails, the opener may try to lift the full door weight, hit the limit, and reverse — leaving the door open just a few inches. Some homeowners mistake this for an opener problem when the root cause is actually the spring.

4. The Door Closes Too Fast or Slams Shut

Springs control descent as well as ascent. A broken or weak spring can cause the door to drop quickly, which is a serious safety hazard for people, pets, and vehicles. If your door slams when closing, stop using it and call a professional immediately.

5. You See a Gap in the Spring or a Stretched Extension Spring

Torsion springs sit horizontally above the door opening. A broken torsion spring will show a clear gap in the coil. Extension springs run along the horizontal tracks on either side — when they break, you may see a separated coil or notice one side of the door lagging behind the other.

6. The Cables Look Loose or Frayed

Lift cables work with the springs to raise and lower the door. When a spring breaks suddenly, cables can go slack, jump off the drum, or fray from the shock. Never attempt to adjust or re-seat cables yourself — they are under extreme tension when the spring is intact and can whip dangerously if mishandled.

7. Your Opener Strains, Hums, or Strips Gears

An opener working overtime to move an unbalanced door may hum loudly, stop mid-cycle, or eventually strip internal gears. Replacing the opener without fixing the spring will not solve the problem — and will likely damage the new unit.

Why You Should Never Replace a Garage Door Spring Yourself

DIY spring replacement is one of the most dangerous home repair projects. Torsion springs are wound under hundreds of pounds of torque. Improper tools, incorrect spring sizing, or a slip during installation can cause serious injury or death.

Professional technicians use calibrated winding bars, measure door weight accurately, and install springs rated for your specific door size and cycle count. Atlanta Entry Systems technicians arrive with correctly sized springs and replace them safely — usually in a single visit.

What to Do If Your Spring Breaks in Metro Atlanta

Disconnect the opener using the emergency release only if you need to move a vehicle out — and only if you can safely lift the door with help. Otherwise, leave the door closed, do not attempt a DIY fix, and call for professional service.
