How to Install a Garage Door Opener

Have you been planning on getting a garage door opener? You know it can be a bit problematic when you don’t own an automated garage door opener. All you have to do is, manually open and close the garage door every time you go out or come back home. I think rather than spending a fortune on a garage door opener, how about you make one yourself?


Although I cannot promise you that the process won’t be a mess or take a little amount of time. For the sake of saving up so much money, spending a few hours installing a garage door opener shouldn’t be a problem.


Setting Up The Rail
To begin with, get a hold of the railing properly and then get the trolleys to attach with the railing. There will be two trolleys. One inner trolley and the other one is the outer trolley. Put the inner trolley on the railing first, and do it the same way for the outer trolley. Connect them. These two will eventually help in opening and closing the garage door.
Now add a stop bolt, having the trolley slid down the railing. Then add the stop nut to retain it.


Time to add the pulley! So go ahead and add it with a belt down the railing with a nut. Note that, you should get the still reinforced belt that has to be encased in rubber. This will result in a noise-less operation every time you will open or close the garage door.


Attaching the Rail
Attach it to the motor now. Make sure you put it through the motor and add a backstop bolt that will hold it properly. After that, put the nut in the right place. Now run the belt to the back pulley and attach it to the other end of the rail.
As one part is attached to the rail, it’s time to attach the other part of the railing. Attach the belt to the tension spring and to do that, use a chain link that would let you keep the belt in the right place. Put it through both holes and then put the master link on top. To secure the whole thing, now put on a clip that will clip all these things together.
Now it is time to tighten up the entire tension spring until the belt reaches the right tension you are looking for.


Attaching the Header Bracket
You are all ready to set the railing up. Before that, you need to set up the header bracket. So, now raise the door and mark the highest point where your door would travel. After you get the mark, get your measuring tape and make another mark two inches above that where you will attach the header bracket.
Now put the bottom of the bracket on the mark and use a two-inch lag bolt that would attach the bracket. You will have to screw the lag bolt into the wall.


Placing the Rail Inside The Bracket
Putting the rail inside the bracket, you have to use a safety ring to secure the position. Note that you would require another couple of hands in this part because putting up a huge rail that high would be difficult for you to handle all by yourself.


Make sure your pin is in a straight position and it won’t slide down.


Mounting Brackets
You have to mount two brackets on the attic that will hold the motor. Now put up the motor and it’s time to attach the motor with the brackets. Make sure all these are aligned in a straight line. Do the calculation with your eyes, that would be all.


Grab a bolt and push it through both of the holes of a bracket. After that, tighter the nut to secure the hold. Use a wrench to tighten these firmly.


Now drill two holes in the door where you will attach another bracket. This bracket will attach the trolley to the door. This time, you have to place the bracket two to four inches below the top of the door. Put bolts and secure the bracket to the door.


Safety Sensors
Add two safety sensors, both facing each other across each side of the door. Add them six feet above the ground. Add wingnuts to place the sensors properly. Staple the wires behind and bring the ends to the motor and plug them in.


Putting On Trolley Arm
The last step is to put on the trolley arm in its place. After that, push it through a pin. Use a middle ring to lock the whole thing in place. Attach the other part of the trolley arm to the door bracket. To seal it, now add another pin. Lastly, put on another ring and you will be good to go with the whole setup


Congratulations! You have successfully installed a garage door opener.


Checking the Sensors
You can check the safety sensors now. Start shutting down the garage door and place your hand through the safety sensors. You will see that your garage door will automatically start getting back up.


Final Thoughts
At first, seeing all the tools, you might freak out but once you will start working on the whole process step by step, just how I showed you, you will be good to go with the whole thing. You can do most parts all by yourself but it’s better to use more hands to finish the whole thing safely in no time.


I am hoping that after going through all these steps you have decided on doing it yourself rather than spending so much on automated door openers. Save the money and install the garage door opener all by yourself within less than an hour. Good luck and happy building!
