5 Signs Your Garage Door Spring Needs Replacing
Your garage door spring does most of the heavy lifting — literally. It counterbalances the weight of the door so your opener doesn't have to strain, and so you can lift the door manually without throwing out your back. When that spring starts to fail, the whole system suffers. Here's how to know it's time to call a professional before a small problem becomes an expensive one.
1. Your garage door won't open all the way
If your door struggles to open, stops partway, or immediately reverses back down, a failing spring is one of the most common causes. The opener is designed to work with a properly tensioned spring — without it, the motor is essentially trying to lift the full weight of the door alone, which triggers its safety shutoff.
2. You hear a loud bang from the garage
A broken torsion spring doesn't fail quietly. If you hear a sharp bang from your garage — often described as a gunshot — and then find your door won't open, the spring almost certainly snapped. This is one of the clearest signs of a complete spring failure and means you need same-day service.
3. The door looks crooked or uneven when opening
Garage doors typically use two springs, one on each side. If one breaks and the other is still intact, the door will rise unevenly — one side higher than the other. This puts stress on the cables, rollers, and tracks and can cause secondary damage if left uncorrected.
4. The spring has a visible gap
Take a look at the torsion spring running horizontally above your garage door. A healthy spring is a continuous coil. If you can see a gap of an inch or more in the coil, that spring has snapped and needs to be replaced immediately. Do not attempt to operate the door.
5. The door feels unusually heavy when lifted manually
Disconnect your opener and try lifting the door by hand. A properly balanced door should feel light — around 8 to 10 pounds of resistance — and should stay in place when raised halfway. If it feels like you're lifting dead weight or it drops immediately when released, the spring is no longer doing its job.
Why you shouldn't DIY a spring replacement
Garage door springs are under extreme tension — enough to cause serious injury if mishandled. This is not a weekend project. A professional technician has the tools and training to replace springs safely and will also check the cables, drums, and hardware for wear while they're at it.
