Chamberlain Garage Door Opener Installation Process

  1. First, you should continuously open and close your door to verify its movement.
  2. Before you get started, set aside the vital parts of your garage door in an area where you can easily see.
  3. Locate the rail from the back of your garage door motor unit and organize it.
  4. Engage the pulley at the rail, slip it inside the slot, and secure it using the bolts and washer.
  5. Place the garage door belt or chain at the idler pulley.
  6. Make sure that you put it in the correct position.
  7. Connect the garage door trolley to the trail and make sure it’s pointing upward.
  8. Next, connect the rail part to the brackets using a large bolt with a nut.
  9. You can now proceed to the garage door header, where it will become the primary support of the end rail.
  10. Afterward, get your metal door opener bracket, then connect it with the header.
  11. In this step, you’ll need a two-by-four tool that you will use to connect to the ceiling.
  12. Before you try this step, get your manual and check if you need a two-by-two as some opener doesn’t need one.
  13. Get a ladder and position it under your motor system, then set up the opener at the top part of your ladder.
  14. Find an assistant who can hold the free end of the door rail and quickly connect the motor unit to the metal bracket using bolts.
  15.  Place the metal door bracket to your two-by-two door hear using lag screws.
  16. Next, connect now the door rail to the metal bracket.
  17. Engage the door arm to the door trolley.
  18.  This door arm is an L-shaped metal that connects your garage door from the trolley to the rail.
  19.  Attach the component using the bolts in order to move at any time you want to use it freely.
  20. Next, attach the LED eye sensor on both sides of the garage door frame.
  21. Make sure not to place it more than 6 inches above the ground level.
  22. They should face each other and should not obstruct their pathway.
  23. Afterward, do a test run of your sensor wiring from the door to your opener.
  24.  Lastly, program your garage door opener.
  25. Make sure to program the remote controller first before operating it.
  26. According to the manual, your garage door should move up and down smoothly, and it should have the capability of stopping halfway when there’s an obstruction.
