A reversible motor that pulls a carriage along a rail above the door powers a standard garage door opener. A drawbar to move the door between its opened and closed positions is attached to the carriage, and travel-limiting mechanisms precisely halt the door’s movement at the completely opened and fully closed positions. Reversing the direction of drive from opening to closing and back again is accomplished with a relay or reversing switch. With the majority of contemporary garage door openers, you may transmit a signal from an electrical module in your car to open the door using a radio receiver.
To install a garage door opener, follow these steps:
Step 1: The mechanism has to be positioned in the door’s middle. Measure the width of the garage door with a tape measure to establish the placement. The center is half this distance away. Draw a short vertical line down the middle of the door from the inside, toward the top. The door weight will be evenly balanced at the lifting point when the drawbar—the device that raises and lowers the door—is attached at this line.
Step 2: Raise and lower the door while keeping an eye on its highest point of travel. Because the opener must be mounted such that the rail is higher than the peak of the door’s motion, make a note of this location. If not, the door can hit the rail as it opens.
Step 3: Look just above the garage door at your vertical dividing line. There should be a support there that can be used to fasten the rail’s front end. Install a front mounting board if there isn’t a structural element in that area of your garage. Using lag screws, center and firmly fix a 2-by-6-inch board length across two wall studs above your mark for the highest door travel. Move your high point mark to this plank and also extend the center line of the vertical door onto the plank.
Step 4: Use the method described in the kit instructions to attach the rail to the motor unit on the garage floor. When the garage door is down, elevate the outermost end of the rail and secure it to the front mounting board approximately two inches above the points where your door’s center line and high point cross. Usually, lag screws are used to secure the rail bracket that is provided for this reason to the front mounting plank. However, you must drill the necessary holes in the front mounting plank if bolts and nuts are provided. you prevent the bolt heads from pushing into the wood, make sure you place washers underneath them.
Step 5: Raise the motor assembly until the rail is parallel to the door track and horizontal. To ensure that the rail positioning does not impede the garage door’s movement, raise and lower the door manually while the motor assembly is held or supported in this position. Using the metal brackets included in the package, secure the motor assembly to the garage joists once the proper height and location have been determined. You must affix a length of 2 X 4 across the joists and then mount the brackets to the 2 X 4 if the motor assembly is positioned between two joists or if the garage joists run in the same direction as the rail. Once the ceiling of your garage is completed, you may install a 3/4-inch plywood panel above the joists and secure it with lag screws. Using strong toggle bolts, fasten the mounting hardware to the plywood panel.
Step 6: Move the rail carriage to its closed-door position and fasten the drawbar to it. Drill the holes in the garage door shown for the drawbar mounting screws. After mounting the drawbar and drilling the holes, put the connecting hardware that secures the drawbar to the door in place and tighten it.
Step 7: Adjust the drive chain or lead screw as needed, paying close attention to where the bolts that restrict the chain’s motion are located.
Installing the manual push button and radio receiver is the eighth step. For the push button, regular bell wire will work just well. Just make sure you position it such that when you press the button, you can see the garage door opener in action. Installing a key switch is an additional option.
Step 9: Insert the extension cord into a handy receptacle and the drive assembly cord into the extension cord. Using the manual push button, raise the garage door. Pull the plug from the extension cable many times during the door’s initial test raising to ensure that there is no binding and that the lifting movement is adequate. Adjust as needed with the garage door opener system’s built-in adjustment features, and make sure the radio remote module is working properly.
Step 10: Plug the drive assembly line cord into its permanent outlet and unplug the extension cord. Attach the line to the overhead light socket in the garage, if at all feasible.
You will now be capable of doing simple repairs on your garage door, whether they be to the door or the opener.
