Home Garage Door Spring Replacement: Signs, Safety, and Professional Service
A broken garage door spring can leave the door heavy, trapped closed, uneven, or unsafe. Professional replacement restores the counterbalance system so the opener is not forced to carry the door’s full weight.
Important Safety Answer
Do not loosen, wind, stretch, remove, or replace a garage door spring yourself. Springs, cables, drums, and bottom brackets can remain under extreme tension. If the door feels heavy or uneven, stop using it and request professional service.
What Does a Garage Door Spring Do?
The spring system counterbalances the garage door. The opener guides movement, but the springs perform most of the lifting. When a spring fails, the opener may strain, lift only a few inches, or stop.
Torsion Springs
Torsion springs are mounted on a shaft above the door and create controlled torque as the door opens and closes.
Extension Springs
Extension springs stretch beside the horizontal tracks. Safety cables help contain a spring if it breaks.
Signs You May Need Home Garage Door Spring Replacement
| What You Notice | What It May Mean | What to Do |
|---|---|---|
| A loud bang from the garage | A torsion or extension spring may have snapped. | Inspect from a safe distance and stop operating the door. |
| The door feels extremely heavy | The counterbalance system is no longer supporting the door. | Do not force it manually or with the opener. |
| The door opens several inches and stops | The opener may be detecting excessive weight or resistance. | Disconnect power and schedule spring service. |
| A visible gap appears in the torsion spring | The spring coil has separated. | Keep people away and call a trained technician. |
| The door rises unevenly | A spring, cable, drum, or track problem may be affecting one side. | Stop use before the door comes off track. |
What Professional Spring Replacement Includes
- Door and hardware inspection: The technician checks the door weight, spring setup, cables, drums, rollers, tracks, brackets, and opener condition.
- Correct spring identification: Replacement springs must match the door’s weight, height, track configuration, and required lifting force.
- Safe installation and tensioning: The old components are removed and the new spring system is installed using proper tools and controlled procedures.
- Balance and travel testing: The door is tested manually and with the opener to confirm smooth movement, correct balance, and safe closing.
If a two-spring system has one broken spring, replacing both is often recommended because the unbroken spring has typically completed the same number of cycles. DASMA advises homeowners to have spring work performed by a trained door systems technician and provides additional garage door safety guidance.
Why the Opener Should Not Lift a Door With a Broken Spring
The opener is not a substitute for the spring system. Repeated attempts can overheat the motor, strip gears, bend the rail, or damage panels. Repair the spring before troubleshooting the opener.

Frequently Asked Questions
Can I open my garage door with a broken spring?
Do not force it. A broken spring can make the door dangerously heavy and may damage the opener or cause the door to move unpredictably.
Should both garage door springs be replaced?
On a matched two-spring system, replacing both is often recommended because both springs have usually experienced similar wear and cycle counts.
Why did my garage door spring break?
Common causes include normal cycle wear, corrosion, incorrect spring sizing, poor maintenance, and additional door weight that the spring system was not designed to support.
Can a broken spring damage the opener?
Yes. Trying to lift an unbalanced door can overload the opener motor, gears, rail, trolley, and mounting hardware.
