Springs are an important part of the mechanics of garage doors. Since garage doors usually weigh hundreds of pounds, opening them without springs is almost impossible for most people and maybe beyond the scope of an automatic garage door opener.
How do garage springs work? When the door closes, the spring swirls, accumulating energy within itself, and releasing the energy that they stored to raise the doorway.
Types of garage door springs
Before we get to the color coding that you find on the garage door springs, let’s see what they are.
Torsion springs save energy by tightly wrapping when the door closes. After the door is closed and at rest, the torsion spring accumulates a huge amount of electricity, and when you want the door to start the spring, it helps, unwinding and releasing this force. Torsion springs sit against the wall through the door.
Extension springs run parallel to the doorway tracks and are usually located above the gate guides. The tension springs, when the door closes, store energy, stretching, and when the door opens, they release accumulated energy.

The color-coding of torsion springs works a little differently. The color code on the torsion spring indicates whether it is a “right” or “left” spring.
The black color indicates the right direction.
The red color indicates the left direction.
In addition, the torsion spring is color-coded so that technicians can determine the depth or size of this wire. Thus, a technician who replaces or repairs a spring can quickly determine its caliber without having to quantify it. Torsion springs also have a straight line through the spring, which helps technicians find out the state of the spring. This line will be geometrically distorted, as the spring is “exposed”. This geometric distortion can be read from the technology and will help him determine how tightly the spring is wound at any given time.

When it comes to expansion springs, the purpose of the color-coding system is to help the organization in supporting your garage doors in determining the lifting force of their springs. This is important because different doors take different numbers into account, and you need springs with the correct load capacity for your individual door.

How to find out the type of spring parameters
The garage door uses 2 types of springs, so it is extremely important to buy the right ones for your doors. Fortunately, determining which type of spring your doorway uses is simple:
- When the springs are connected to the wall directly above the doorway, you have torsion springs. Some doorways use a single spring, while most new doorways use two springs.
- When the springs can be found above the tracks and run away from the doorway to the opener, you have an extension spring.
Now let’s see how to choose the right torsion bar or extension spring.
Torsion Spring Direction – Before you can get the perfect torsion spring, you want to know how it is wound. Look at your springs in the garage. Most new garage doors will have two torsion springs, separated by a partition located in the middle of this doorway. The spring on the right is “left”, and the spring on the left is “right.” Therefore, if the spring to your left is broken, you would like to buy a “right” spring.
Torsion spring wire size. Sizing the wire is also a simple process. Just measure the distance between 20 turns of the spring and use the waistline above to determine exactly your spring.
Internal diameter and the total length of the torsion spring. In some cases, the internal width of the torsion spring is indicated on a static cone between the two springs at the midpoint of the doorway. “1.75” means that the inner diameter is 1 3/4 of an inch. “2” means that the inner diameter is only two inches. If you cannot find the size sign, simply measure the inside diameter. In terms of determining the total length, just take a tape measure and quantify it at the place where the spring begins, where it ends. If the spring is broken, simply measure its auxiliary spring, which will be exactly the same length.
Choosing the ideal extension spring. Although quantifying torsion springs to be sure to get the perfect spring is pretty simple, getting the perfect extension spring is a lot easier. This is because the garage door springs have a color strip on them, which means that their sizes. Therefore, all you have to do is find this color index and pass the color you found (yellow, red, blue, orange) to the extension spring supplier.
But what to do until the spring is replaced, do not use the garage? Do not worry, how to open the garage door with a broken spring, we already told!
