Your garage door springs do the real lifting. The opener just guides the door; the springs carry the weight, which on a typical door is 150 to 250 pounds. When a spring weakens or breaks, all of that weight lands on the opener (or on you). Here are the six signs Bay Area homeowners should never ignore.
1The door feels extremely heavy to lift by hand
With the opener disconnected, a properly balanced door should lift with one hand and stay put halfway. If it feels heavy or drops, a spring has lost its tension. This is the clearest sign of spring failure.
2You heard a loud "bang" from the garage
A breaking torsion spring releases a huge amount of stored energy at once — it sounds like a firecracker or a heavy metal pipe hitting concrete. Many customers think someone broke in. If you heard that sound and now the door won't open, that's a snapped spring.
3The door opens a few inches, then stops
When a spring breaks, the opener's safety system senses the extra weight and stops to protect the motor. A door that lifts 6 inches and quits is a classic broken-spring symptom.
4There's a visible gap in the spring
Walk into your garage and look at the spring(s) above the door. A healthy torsion spring is one tight, continuous coil. If you see a two-inch gap where the coil separated, the spring is broken — do not try to use the door.
5The door closes too fast or slams shut
A door that drops quickly or slams instead of lowering smoothly has lost spring tension. This is dangerous: a door coming down under its full weight can injure a person or crush whatever is under it.
6The cables have gone slack or come off
When a spring fails, the cables that work with it often go loose or jump off the drum. Loose cables hanging beside the door are a sign the whole lifting system needs attention.
Why you shouldn't keep using a door with a failing spring
A garage door under spring failure is one of the most dangerous things in a home. The door can fall without warning, the opener can burn out from the strain, and trying to force it can snap a cable under tension. If you're seeing any of these signs, stop using the door and get it looked at.
How Five Star fixes it
