What Does a Garage Door Spring Actually Do?
Garage door springs are responsible for counterbalancing the weight of the door.
There are two main types:
- Torsion springs (mounted above the door)
- Extension springs (on the sides)
These springs store mechanical energy and release it to lift the door smoothly.

Top Signs Your Garage Door Spring Is Broken
Let’s break down the most reliable indicators.
1. You Heard a Loud Bang in the Garage
Many homeowners describe it as:
- A gunshot-like sound
- A sudden snap
Why it happens:
The spring is under extreme tension and releases all energy when it breaks.
2. The Garage Door Won’t Open
This is one of the clearest signs.
- The opener runs, but the door doesn’t move
- Or it lifts only a few inches
Reason: The spring is no longer supporting the door’s weight.
3. The Door Feels Extremely Heavy
Try lifting the door manually (carefully).
- Normal: manageable weight
- Broken spring: feels very heavy (100–300 lbs)
Important: Do not force it—this can cause injury.
4. Visible Gap in the Spring
Inspect the torsion spring above the door.
- A broken spring will have a 2–3 inch gap
- The coil appears separated
This is a clear visual confirmation.
5. Door Opens Crooked or Uneven
If one spring breaks:
- One side lifts faster than the other
- The door tilts or jams
This can damage tracks and rollers if ignored.
6. Garage Door Opener Struggles
You may notice:
- Motor runs but door doesn’t move
- Opener stops suddenly
- Unusual strain noises
Tip: Modern openers have safety features that prevent lifting heavy loads.

What Causes Garage Door Springs to Break?

No lubrication leads to faster deterioration.

Cold weather can make springs brittle and prone to snapping.
