1) Door Opener

The door opener is the operator that houses the motor, which supplies power to the entire system. The door opener is the garage door’s brain box as it is responsible for controlling the whole system of the door. This part of the garage doors is fixed to the garage ceiling and controlled by either a wall button, remote, keypad. Nowadays, door openers are connected to a Wi-Fi system, thereby allowing you to manage your garage door through an app on your phone or any other device.

The door opener has different parts, and one of them is the drive mechanism. It is responsible for the heavy lifting of your door when you open it and also lowering it down when you close it. Other parts of the door opener are the belt or chain and the emergency release rope.

The belt or chain is used to join the garage door with the carriage and trolley. This carriage is the equipment that is pulled onward the horizontal track to open and close the door. Simultaneously, the trolley is the instrument used to join the carriage to the belt of the chain. If there is no power or your door opener is faulty, the emergency release rope allows you to disengage from your carriage and instead close and open your door manually.

2) Sensor

The garage door sensor is a piece of safety equipment that is used to prevent an accident in the garage. This part of the garage door senses if there is someone or thing under the garage door before closing to ensure that the door doesn’t fall on them. These sensors are stationed near the floor at both sides of the garage door.

The sensors work by emitting a laser. One sensor emits a laser while the other receives it; if a thing or person intercepts the laser, the garage door will not close. However, not all garage doors have these sensing edges. If you have children and pets, a garage door with sensors is the best option for you as it will help prevent the garage door from falling on them.

3) Tracks

The garage door tracks are the pathways that secure the door rollers and allows them to glide through from the floor to the garage ceiling whenever you want to open or close the garage door. These tracks are fixed above and on both sides of the garage door.

The track’s rollers are made from materials such as plastic, metal, or nylon. Do not lubricate your tracks. Instead, wipe them down occasionally using soap and water and ensure that your track is devoid of leaves, dust, and any other unwanted material. However, you can apply lubricants to your rollers twice a year or as soon as they start making any noises.

4) Sections and Hinges

Every garage door has several sections or panels. They are rectangular, and these sections beautify the garage door as they come in all types of colors and designs. Some garage door sections can have windows and also contain fancy hardware. They are made from materials such as vinyl, steel, wood, aluminum, fiberglass, etc.

On the other hand, hinges are the joints that connect the panels. They also allow the panels to transform from a vertical to a horizontal shape by folding and retracting into the ceiling whenever you want to open the door.

5) Torsion Spring

The torsion spring is a heavily coiled, vital piece that is fixed precisely above the garage door. While the motor produces all the energy needed to lift the door, the torsion spring makes the door’s movement easy. With its strong elasticity, the torsion spring holds and equalizes the weight of your garage door. For manual garage door owners, the torsion spring is what makes it easy for you to lift your garage door. If your torsion spring is faulty, do not attempt to fix it yourself because it is always under extreme tension. Instead, contact a professional to fix it for you.

6) Cable Drums

Along with the torsion spring, the cable drum is responsible for balancing the garage door’s weight. The drums are ring wheels attached to a tube above the torsion spring. When the door is moving, the drum rotates and moves up or down the cable in correlation with the door’s movement.

7) Weather Seals

The weather seal is used to protect your garage door against bad weather and other outside elements. A good weather seal prevents your garage door from being affected by snow, rainfall, pests and keeps away any other factor that can damage your garage door. This part of the garage door is located at the bottom and sides of your garage door.

Conclusion

Every part of the garage door plays a significant role in ensuring that your garage door lasts for a long time. It is best to buy your garage door from a physical store and ensure you check that the parts are in good condition. Make sure you choose a garage door that matches the color of your home and adds to the aesthetics as well.
