How to Install a Garage Door Opener

Automatic garage door opener installation is something that even a casual do-it-yourselfer can handle. Stop wasting time getting in and out of your car to open the garage door and put in an automatic opener.

Instructions

  • Step 1: Open and close the door to ensure it moves freely. Then attach the L-shaped linkage assembly to the traveler. Attach the door bracket to the door at the manufacturer-recommended height and then connect the free end of the L-shaped assembly to the bracket.
  • TIP: Federal law requires that photoelectric sensors be installed with electric garage door openers.
  • Step 2: Mount the keypad or push-button control on a wall adjacent to the door at a height of about 5 feet. Then run the wire along the wall and ceiling and connect it to the power unit.
  • Step 3: Plug the unit in and turn it on. Test the remote control, the control button or keypad, the sensors, and the release cord. Never have to manually open your garage door again.
  • FACT: The Home Depot is the world's largest home specialty store, and the fourth-largest retailer in the United States.
  • Step 4: Mount the infrared beam sensors on either side of the door, about 6 inches from the floor. Then connect the sensor wires to the power unit, running the wires along the walls and ceiling.
  • TIP: If the ceiling in your garage is finished, use a stud finder to locate ceiling joists.
  • TIP: Position the traveler and adjust the chain tension according to the manufacturer's instructions.
  • Step 5: Attach one end of the chain to the traveler; and run the chain around the drive sprocket, down the track, through the idler assembly, and back down the other side of the track. Then connect the loose end of the chain to the other end of the traveler, making a closed loop.
  • Step 6: Use your drill to attach a bracket to a header or beam above the center of the garage door, and, with the power unit resting on the garage floor, bolt the idler assembly at the end of the track to the bracket.
  • Step 7: Raise the power unit high enough to allow for garage door clearance, rest it on a stepladder or other platform, and then open the garage door. Insert shims beneath the power unit until the track is level.
  • Step 8: Attach angle steel and mounting straps to ceiling joists and mount the power unit to the straps. If the ceiling joists are not perpendicular to the door, nail two-by-fours between two joists and attach the mounting gear to the two-by-fours.
  • Step 9: Insert the track tube or rail into the power unit and slide the traveler, or carriage, onto the tube. Then assemble the remaining track sections and make sure that the traveler moves freely over the track.
