How Automatic Garage Doors Work

Automatic garage doors have simplified the way we enter our homes or offices. They offer a combination of convenience and security. But how do they actually work? 

Let’s explore the mechanics behind automatic garage doors and what makes them so convenient and easy to use. We’ll go through their crucial components and troubleshooting tips, so you’ll gain insights that will keep your door functioning smoothly in the future too.

Essential Parts of Automatic Garage Doors

Automatic garage doors rely on several key components to function. Each part plays a specific role and brings smooth operation and security.

We’ll go through the role of:

• Garage door opener,
• Keypads,
• Springs,
• Garage door tracks,
• Photo eye sensor.

Opener and Keypad

The opener and keypad are the heart of automatic garage doors. The opener, usually mounted on the ceiling, houses the motor that powers the door’s movement. With just a click, it smoothly raises or lowers your garage door.

Keypads provide convenience at your fingertips. They allow easy access without needing to fumble for keys or remote controls. Most keypads use a simple code system, which is how you can be sure that only authorized users can operate the door.

Today’s technology has advanced even further with smart openers for modern homes. These connect to Wi-Fi networks and you can control the access via smartphone apps. 

Additionally, modern systems also include safety features. Many have rolling codes that change each time you enter your PIN, which can upgrade security against unauthorized access.

Springs and Tracks

Garage door springs and tracks work together to ensure smooth operation and reliable performance.

The springs, typically torsion or extension types, store energy when the door is closed. When activated, they release this energy to help lift the heavy door with ease. At the same time, tracks guide the door as it opens and closes. These metal channels keep everything aligned, allowing seamless movement without jamming or sticking.

Proper maintenance of both springs and tracks is a must. Regular inspections can prevent costly repairs down the line and extend the lifespan of your garage door system. So, if you notice any unusual sounds or difficulty opening your garage door, you should check these parts immediately. 

Photo Eye Sensor

The photo eye sensor is the most important safety feature of automatic garage doors. It acts like a guardian, ensuring nothing obstructs the door’s path when it closes.

This small device operates using radio frequencies and consists of two components: an emitter and a receiver. The emitter sends out an invisible infrared beam to the receiver. If something interrupts this beam while the door closes, the system automatically reverses direction.

These sensors are typically located near the ground on either side of the garage door frame. For optimal performance, they should be kept clean and free from obstructions.

When they’re properly functioning, they prevent accidents and protect both people and vehicles from harm. This is why you need to check them regularly as well, and make sure they’re in good condition.

Do Automatic Garage Doors Open When Power is Out?

Many homeowners wonder about their automatic garage doors when the power goes out. Can they still open? The answer is yes, but it requires a little effort.

Most automatic garage doors come with an emergency release feature. This mechanism allows you to disengage the opener from the door manually. Typically, it’s a red cord hanging from the garage door motor unit.

When you pull this cord, you will be able to lift the door by hand. However, keep in mind that if your garage door is heavy or has strong springs, it might be challenging to operate without assistance.

Additionally, some modern systems have built-in battery backups. These can keep your garage functional even during outages. Be sure to check if yours has this handy feature for extra convenience when unexpected blackouts occur.

How Often Should Garage Doors be Serviced?

We’ve mentioned regular maintenance of your garage door several times so far. Most experts recommend servicing your automatic garage door at least once a year. This ensures that all parts are functioning correctly and helps to identify any potential issues before they become serious problems.

During the service, a technician will inspect various components like the opener, springs, tracks, and safety sensors. They’ll lubricate moving parts to reduce wear and tear. They will also check the alignment of the photo eye sensor, which is extremely important to maintain safety standards.

If you notice unusual noises or if your garage door isn’t operating smoothly, it’s wise to have it checked sooner rather than later. If you fix minor problems early, you can save yourself from costly repairs down the line.
