No matter who repairs the garage door, when the door is damaged, it is you, who has to identify the problem first. For that, you need to know about the various parts of your garage door.
The following garage door parts diagram will help you in this regard.
All the garage door parts can be divided into three main categories, the frame, moving parts, and the garage door opener. The frame of the garage door consists of the parts that are fixed in their places, such as the tracks, brackets, etc. The moving parts include the roller, springs, cables, etc. And the garage door opener includes, well, the opener itself.
Let’s take a detailed look at a diagram of garage door parts.

As garage doors have a lot of parts, it is natural that they will wear down over time, either due to continual usage or for some other reasons. When that happens, you have to take measures to repair the damages immediately.
But how can you take appropriate measures if you don’t know what is wrong with your garage door?
To know what is wrong with your garage door, you must know about the parts of the door and their functions. Here are the garage door parts’ names, diagrams, and related details every one of them.
Garage door frame
The garage door frame includes the stationary parts which don’t move at all. The parts of the garage door frame include:
1. Garage door tracks
Garage door tracks are installed all around the door, and they are fixed to the wall. These metal tracks are used as a pathway for the garage door rollers to move, which enables the door to move up and down smoothly.
There is also a trolley track, which is situated at the door’s center. This track, which is attached to a spring, uses garage door cables to move the door.
2. Garage door brackets
There are two types of garage door brackets, the flag bracket and the jamb bracket. The function of these brackets is to attach the garage door tracks to the ceiling as well as the walls.
These brackets also attach the roller to the garage door.
3. Garage door hanger kits
The hanger kits, which are made of galvanized steel, have punched holes in them. These are used to attach the garage door opener to the garage’s ceiling. They can also be used to attach garage door tracks to the ceiling.
The hanger kits can be adjusted for the height of the door, and the ceiling.
4. The bottom rail
The bottom rail is one of the most underrated parts of a garage door. These make sure the door is closed and kept in place properly. If the bottom rails are damaged, or the floor is uneven, then the door will not be properly closed, which will allow water, pests, and debris into the garage.
Garage door moving parts
A typical garage door has a lot of moving parts. These parts are usually smaller than the parts of the garage door frame and tend to get damaged more often. These parts include –
1. Garage door rollers
The rollers of the garage door are small wheels that are attached to the garage door. These wheels run along the garage door tracks and move the door up and down smoothly.
2. Garage door hinges
The hinges of the garage door are situated in different places according to the type of door. If the door is a traditional side-hinged one, then the hinges are situated at the sides of the garage door.
On the other hand, if the garage door is a sectional garage door, then the hinges are attached to each section of the door, which allows the sections to bend over the curved section of the track.
See the garage door hinge diagram for a better understanding.
3. Cable and pulley
There are a lot of parts of the garage door that work to ensure the door moves along the tracks smoothly. The pulley and cable of the garage door are two such parts. The garage door cable is attached to both the opener and the garage door springs. These cables pull the garage door to open them.
Since garage doors can weigh over 250 pounds, there is every chance that the cable will snap under the immense weight. This is where the garage door pulleys come in. They provide much-needed mechanical support to the cable, so that the door can be opened by it, and closed gently as well.

4. Cable drum
Depending on the type of garage door, there can be one, or more than one cable drum in a garage door. These drums contain the aforementioned cables and release them as they open and close the doors. One of the main reasons garage doors don’t open is when the drums get loosened.
5. Curved door arm
The curved door arm is a small part of the garage door, which is attached to its trolley. This connects the door with the garage door chain, or belt, and ensures the door moves smoothly.
6. Garage door spring
Garage door springs are one of the most important parts of the garage door system. These springs open and close the garage door by coiling and uncoiling, which puts a force on the door. When the garage door springs are damaged, your door won’t be able to open all the way.
7. Garage door chain, belt, or screw
Garage door chains are metallic chains that open and close the door. Sometimes these chains get misaligned, which can be fixed by you. These chains are noisy, which is why people often prefer belts, which operate the same way as the chain.
On the other hand, garage door screws are threaded pieces of metal that rotate the motor of the garage door, as a result of which the door moves up and down. These are the most expensive of the three options, but they are durable and don’t need to be adjusted.
8. Emergency release cord
The emergency release cord is a red cord that needs to be pulled to detach the garage door from the garage door. This is put in place so that you can open your garage manually in case a power outage takes place.
This is one of the most important electric garage door components.
Garage door opener
The garage door opener is a motor that is attached to the ceiling of the garage. This motor produces power so that the other parts can work together and open or close the door. Contrary to popular belief, the owner doesn’t do most of the work. It merely produces enough power so that the cable, chain, and spring can operate the door.
