One morning, your garage door works fine. Next, it will not budge. That is how springs fail, and it happens more often than most property owners expect. If your door stopped moving or sounds different than usual, the spring is the first place to check.
What Garage Door Springs Do
Garage door springs carry the full weight of the door every time it opens and closes. Without them, the opener motor alone cannot lift the door. Most residential doors weigh between 130 and 400 pounds, and commercial doors can go much higher. The spring system does the heavy lifting on every cycle.
There are two types of springs in common use:
- Torsion springs are mounted above the door on a horizontal bar
- Extension springs are mounted on either side of the door along the horizontal tracks
Torsion springs are more common on commercial and heavier doors. Extension springs are found on lighter residential setups. Both have a finite lifespan. The average torsion spring is rated for about 10,000 cycles, which works out to roughly 7 to 9 years with regular daily use, according to data from the International Door Association.
Signs That Point to a Broken Spring
The Door Will Not Open at All
This is the most obvious sign. When you press the opener button and the door barely moves or stays completely down, a broken spring is the likely cause. The motor strains but cannot lift the weight without spring support.
The Door Opens a Few Inches Then Stops
Most modern openers have a safety feature that stops the door when it detects too much resistance. If the spring is broken, the opener hits that resistance limit almost immediately and stops. You will notice the door lift slightly and then reverse back down.
You Hear a Loud Bang From the Garage
A spring breaking under tension produces a sharp, loud sound. Many people describe it as a firecracker or a gunshot. If you heard that sound and your door stopped working right after, the spring snapped.
The Door Looks Uneven When It Moves
For doors with two extension springs, one side may still function while the other does not. This causes the door to tilt or look crooked as it moves. For commercial properties with wide doors, this kind of imbalance puts serious stress on the tracks and the opener.
You Can See a Gap in the Spring
With torsion springs, you can sometimes see a visible separation or gap in the coil where it broke. This is a direct confirmation. With extension springs, you may notice one spring hanging loose or stretched differently than the other.
Why This Is Not a DIY Fix
Garage door springs are under high tension at all times. Handling them without proper tools and training carries serious injury risk. According to the U.S. Consumer Product Safety Commission, garage door-related injuries send thousands of people to emergency rooms each year, and spring-related incidents are among the leading causes.
For commercial properties, the risk is even higher. Heavier doors use heavier-gauge springs with more stored tension. Attempting a replacement without the right equipment can result in the spring releasing and causing serious damage or injury.
Broken spring repair in San Diego requires a technician who knows the correct spring sizing for your door weight and how to release tension in a controlled way. Getting the spring size wrong also shortens the life of the replacement and puts extra load on the opener.
What Happens If You Keep Using a Door With a Broken Spring
Some property owners try to manually force the door open or run it through the opener repeatedly. Both approaches cause additional damage:
- The opener motor burns out faster under the extra load
- Cables can snap or come off the drum
- Tracks can bend or pull away from the wall
- The door can drop suddenly, damaging vehicles or injuring people
For a commercial warehouse, loading dock, or parking structure, a door that drops without warning is a serious liability. Getting broken spring repair in San Diego done right away is the lower-cost and lower-risk path.
How Repair Process Work
A professional technician will:
- Inspect both springs even if only one broke (if one goes, the other is close behind)
- Measure the door weight and select the correct spring gauge and length
- Release any remaining tension in the old spring safely
- Install and wind the new spring to the correct tension setting
- Test the door balance and opener force settings after installation
For commercial properties, this process also includes checking cables, drums, and the opener limits to make sure everything is calibrated after the spring change.
