You know, your garage doors the heaviest moving object in your house. So before we start to install Dave and Ginas opener, were gonna take a few minutes and make some safety checks on this door and also make sure that its operating properly.

Okay, Dave, could you pull that door up there.


One of the first things I notice is that Dave and Ginas garage door, like many, has steel wheels. I suggest replacing them with new Teflon wheels which will run smoother and quieter, especially important on a metal door like theirs.

To make the changeover, we bend the track open temporarily and slip out each wheel. Then pull the wheel from its mounting bracket and replace it with a Teflon version. The wheel is then slipped back into the track. When all the wheels on one side have been replaced, the track is simply bent back into its original shape.


Next we take a moment and oil the hinges. One or two drops on each pivot point will keep a roll up door squeak free and operating effortlessly. The final step in our garage door tune-up is to tighten all the nuts, bolts and screws. A sectional garage door, especially a wooden one can weigh up to 1000 pounds. Now thats way too much weight for you to lift up yourself, so they use torsion springs like these up here to do that lifting for you.

Now these springs are adjustable and heres a simple test that you can do yourself to see if theyre adjusted properly.


Lift the door all the way up and then pull it down about a foot. Let go of it and it should go back up by itself. Then pull it halfway down. Release it and it should stay put. Bring it all the way down to within about a foot of the floor, let go of it and it should gradually go to the bottom.

This one is not, which means that that spring up there probably needs some adjustment. But that is a job for a professional. Gary Spivey installs and adjusts garage doors for a living. He makes two important points. One, torsion springs need to be correctly adjusted. Too much or too little tension can damage garage door openers and be downright dangerous if youre opening and closing the door manually.

And two, never attempt to do this job yourself. If the energy stored in these coiled up springs is unleashed accidentally, it can cause serious injury. The heart of a garage door opener is the drive unit. In it, theres a motor that moves a chain or drive screw to pull a carriage or traveler along a track.

The carriage connects to the door with a bracket that allows the motor to raise and lower the door.

Heres the motor —




And heres the rail.

A track comes in sections. I attach the first section to the drive unit, Gina and Dave connect the remaining sections together. This carriage which Gina is slipping into the track will move back and forth when the motor is operated.

Next, Dave attaches a bracket to the end of the track which we are about to mount to the beam or header above the garage door.

Okay, Gina. Just come up on the ladder there. Okay, all the way up. Let me put this in now.




Okay just let me have —

Once the bracket end of the track is attached, we raise the door and lay the track and motor assembly on top where it will rest until we get ready to mount the drive unit. The motors heavy, so it must be attached directly to a ceiling joist.

The joists in this garage ceiling are covered with drywall, so well use a stud finder to locate them. Next, we attach a piece of perforated angle iron, using lag screws. We attach two short vertical pieces of angle iron to the drive unit.

Now were gonna push this up. And then Im gonna run some bolts through here.

Once the bolts are tightened, the motor and entire track assembly is supported in place. To conceal the wire running to the wall switch, we poke a small hole in the ceiling. Then Dave heads up into the crawl space while Gina feeds the switch wire through the hole.

Can you see where the hole is?


Yeah, I got it. I got the pliers side on it.


Okay. Im gonna send up the wire.


Over near the wall, we make a second hole. Gina inserts a coat hanger to help pinpoint the spot. Dave attaches the wire to the end of the coat hanger, and Gina pulls it back through. Next, we attach the end of the wire to the switch and snap it onto the base plate.

Garage door openers, especially older ones, are potentially hazardous, even fatal to small children and pets that might get trapped underneath them. Thats why all new garage door openers come with these infra red beams. If anything breaks this beam, the door on its way down will stop and immediately reverse before theres any contact.

The sensors are typically located on either side of the door about six inches from the floor. A wire is run from the sensors back to the motor. Now its time to connect the garage door to the door opener. The best way to do this, and especially on a metal door is to first install a heavy duty reinforcing bracket like this one.

Finally, we attach one of these L-shaped arms to the reinforcing bracket and a second to the door opener. Overlap the two arms, insert pins into pre-drilled holes and were ready to put our work to the test.

Wow, look where it sits.


I know. Were very excited.
