Learn the Essential Parts of a Garage Door and Garage Door Opener

Parts of a Garage Door opener Canada

Today’s garage doors and openers have several different mechanisms that work together to move your garage door. Though they may seem like simple machines, there’s quite a bit behind the scenes.

In this blog post, we’ll break down the essential parts of garage door openers to help you understand how they work.


The switch or operator is the brains of the garage door opener. It controls the up and down movement of the door and other added features. Some switches attach to the wall near the garage door, while others come in a separate remote control.


Without springs, your garage door opener would need to do all the work to lift your garage door. These mechanisms help balance the door and make it easier to open.

There are two types of springs – torsion springs and extension springs. Torsion springs twist as the door opens. You can usually find them above the garage door. Extension springs, meanwhile, are on either side of the door and stretch as the door opens.


Most garage door openers have sensors that detect when an object is in the way of the door, preventing the door from closing and hurting anyone or damaging property. You can usually locate them at the bottom of the garage door frame on either side.

If your door can’t open or close fully, it might stem from a faulty sensor. Pinched wires, misalignment, or cloudy lenses are the most common culprits.


Rollers guide the garage door along the tracks on either side of the door. They often come in steel or nylon and attach to the door with brackets.

As the door opens, the rollers roll along the tracks until they reach the end. Then, they pivot and roll back toward the middle to help balance the door.


Many parts of a garage door rely on cables for movement. These components often come in tough steel that can withstand lots of wear and tear.

You can find cables running along the sides of the garage door, through the springs, and even attached to the bottom brackets. These cables work together to lift and lower the garage door smoothly.


Tracks are one of the most important parts of a garage door system, serving as a guide for the door as it moves. They also provide support for the springs and cables.


Hinges are what connect the various garage door sections and keep them together.  They allow the door to swing open and closed while supporting the door’s weight. You can find hinges on either side of the door.
