Even the best garage door systems are not resistant to damage. Garage doors are one of the largest and most frequently used parts of our home. Springs are made to function within 5% of their calibration, so if spring is installed on a door that’s way too heavy, it will eventually snap under pressure. Keep reading to find out what happens when a garage door spring breaks and what to do if you find yourself in this situation. 

What Happens When a Garage Door Spring Break?

What Happens When a Garage Door Spring Break

Garage doors can be sturdy but not breakable. Knowing this, manufacturers galvanize their springs up to 30-40%, but even with this protection, springs will still rust. Damaged springs are usually ignored until the door stops functioning. The signs below will answer your question: What happens if the garage door spring breaks?

A sudden noise from the garage

If you hear a loud noise in your garage but can’t see anything during an inspection, take a closer look. The sound you heard was probably caused by the sudden onset of spring. They can make a loud bang sound when the springs break, even if the door hasn’t fallen.

Spring gap

A broken spring is the best way to identify a broken spring. From end to end, the springs should be tightly twisted and connected.

Fold the door at the top

Another sign of a broken spring on your door is that the top panel flexes when you try to open the door. Without functional springs, the door opener will not be sufficient to lift the weight of the door panels.

Garage doors are falling fast

The functional garage door opener and spring gently lift and reduce the weight of the door. The door can collapse when the spring breaks because it no longer has a counterweight to gravity on the door panels.

Door is crooked

The door may open or close depending on the weight of the door, the number of springs it contains, and the number of broken springs. As you go up or down the road, you may see that the door curls. This is because the weight is no longer distributed uniformly.

Loose cables

broken spring can cause further snowball problems. Loose cables are often caused by broken springs. When the spring breaks, the cables and pulleys can loosen, and you may notice loose cables hanging from the ceiling.

Causes of Garage Door Breakage

Garage door springs break by accident and carelessness. A few examples of what can cause a spring to break are listed below.

  • Rust
  • Bad Maintenance
  • Wear and tear
  • Defective parts


Corrosion is a problem with metal springs. Rust reduces spring and increases friction, shortening the spring cycle. Rust can be prevented by periodically spraying the spring with a lubricant such as WD-40.

Bad maintenance

Garage doors do not require any special maintenance. Spray WD-40 springs from time to time and check for any obstructions on the way or the ground in the gate’s path. These small steps and a visual inspection of your garage door system every few months can help you pinpoint problems before they cause havoc.

Wear and tear

Most garage doors are usually used. Regular use will cause normal wear on the springs, which will eventually damage them. The more they wear out, the faster the springs respond. Springs should be replaced if they are rusted, deformed, or broken.

Defective part

It is important to use the correct spare parts for your garage door. Springs are one of the most important parts of your garage door system – they lift heavy objects. Installing unsuitable springs can lead to faster spring wear and damage to other parts of the system.
