How Do Garage Doors Work?

Garage doors can operate based on two different systems: torsion spring systems and extension spring systems. Extension spring systems use springs attached to cables that connect to the bottom corners of a garage door. These springs are stretched when the garage door is closed, and when it is opened, they contract and pull the garage door upward.


Since extension springs aren’t very durable, most garage doors use torsion spring technology. These types of springs are usually located above a garage door’s opening, and they cause the opening cables on the garage door to wind as the door lowers. When the door is lifted, these springs unwind and exert kinetic energy.

Whether they use extension spring or torsion spring technology, garage doors are opened with a type of motor called an operator. It doesn’t take much energy to open or stop a garage door; most of these motors have 1/2 horsepower engines, and they only use six amps of 120V electricity.


These motors may also include inverters that transform DC electricity into AC electricity. In addition, most motors have small buttons that you can use to adjust the height of the garage door when it is closed.


Garage doors use a variety of drive mechanisms to move. Drive belts are the quietest types of drive mechanisms, and they are usually made from kevlar. On the opposite side of the spectrum, garage door chains are the loudest and cheapest options, and the garage door screw is a happy medium between these extremes.


When a garage door motor is activated, its spring mechanisms start moving, and the garage door’s segments move up or down along the track using one of the drive mechanisms we’ve covered. Once the garage door has reached its fully extended or retracted position, the operator stops, and the garage door comes to a resting position.

What Are the Components of a Garage Door?

Garage doors contain a number of different components. If you want to learn more about your garage door, you’ll need to familiarize yourself with each of the following parts:

Sections: Your garage door is composed of a number of different lateral sections that all connect together with hinges. These sections can be made from materials like wood, fiberglass, aluminum, or even glass.

Tracks: The sections of your garage door move up and down along tracks. These tracks are installed vertically on the walls on either side of your garage door.

Hinges: These components are stationed between each of the sections of your garage door. They allow your garage door to fold slightly as it moves up and down.

Motor: This component gives your garage door the power to move up and down. It is housed on the ceiling of your garage. 

Bottom fixtures: These components are stationed at either side of the bottom of your garage door. They provide your garage door with structural support, and they are points of attachment for your door’s lifting cables.

Torsion springs: These springs move your garage door sections up or down when the motor is engaged.

Cable drums: These drums contain your garage door’s lifting cables.

Top fixtures: Also known as top brackets, these fixtures provide points of attachment for your garage door’s lifting cables. They also support the garage door.

Operator hanger: This component provides support for your garage door motor.

Rear track hanger: This part attaches at the rear extremity of your garage door’s track to provide extra support.

Safety sensors: These components are deployed at the base of your garage door, and they make sure that your garage door won’t shut if there is an obstruction under the door.

Emergency pull cord: You can pull this cord to disengage the garage door motor. Once pulled, you can raise or lower your garage door manually.

Garage door opener: This button is usually located near the inner door of your garage. You can press it to raise or lower your garage door. In some cases, another garage door opener may be stationed on the outside of your garage that you can use to open your garage door by inputting a keycode.

Garage door remote: You can use these devices to open your garage door from a distance.

How Long Do Garage Doors Last?

Garage doors last an average of 10-15 years. If you don’t open your garage door very frequently, it’s possible to make this part of your building last longer. Also, keep in mind that it usually isn’t necessary to replace your entire garage door when it fails; if fact, it’s usually just a spring, hinge, or motor that’s at fault.

Common Garage Door Problems

1. Garage door opener doesn’t work


If you’re standing in your garage pressing the opener button over and over again to no avail, you’ll need to address an issue with your garage door’s opening mechanism. In some cases, this issue can be caused by a dead battery in your opener, but there may also be an issue with your garage door motor’s wireless receiver.


2. Garage door closes and immediately opens


If your garage door doesn’t seem to want to stay closed, then there’s probably an issue with the safety eyes at the base of your door. Make sure that both of these eyes light up and that they’re free from obstructions.


3. Garage door doesn’t go all the way down


If your garage door doesn’t go all the way down to the ground, you could have an issue with the height adjustments on your motor. Physical damage to your garage door can also cause this issue.

Garage Door Frequently Asked Questions (FAQ)

Here are some of the garage door questions that customers most frequently ask us:


1. How much headroom do I need?


Headroom is a term that’s used to refer to the distance between the top of your garage door and the lowest point on your ceiling. This term can also refer to the distance between the door and the lowest obstruction such as pipes or ductwork.


In most cases, a minimum of 10 inches of headroom is required to make sure that your garage door operates safely. However, some commercial garage doors may require up to 16 inches of headroom.


2. How much do garage doors cost?


The price of a garage door depends on a number of different factors. For instance, bigger garage doors are more expensive than smaller models, and garage doors with lots of decorations or that use high-quality materials are also more expensive. Furthermore, the condition of the site where you want a garage door installed also affects the overall installation price.


3. What is R-value?


R-value is a measurement of thermal efficiency, and it applies to garage doors, walls, windows, and other building surfaces that make contact with exterior environments. The higher the R-value of your garage door, the better it will resist changes in temperature and insulate your building. Read more about R-Value here
