How to Replace a Garage Door Opener

Garage door openers are such handy appliances, yet we take them for granted every time we use them. Unfortunately, even the most faithful garage door opener eventually stops working. Since the track is already in place, it's not hard to replace the old garage door opener with a new one. Follow all the manufacturer's directions as you install your new garage door opener. Read on to learn how to replace a garage door opener.

  1. Remove the old opener. You must install the new garage door opener in the center of the door. Use a tape measure to find the exact center, and mark it with a vertical line.

  2. Observe the high point of the door as you raise it. Mark that spot. Attach a support piece of 2-by-6 lumber to the studs at that point, if they're not already there.

  3. Attach the front end of the rail to the door where you drew your vertical line on the door. There should be a reinforced panel for this purpose already there.

  4. Assemble the rails according to the manufacturer's directions. Put the garage door down.

  5. Lift the motor assembly to a point that puts the rail in a horizontal position. Raise the door manually to make sure the rails are out of the way. If you are satisfied with the position, fasten the motor to the ceiling joists with the brackets that come with the door opener kit.

  6. Move the carriage to the closed-door position. Attach the drawbar to the door. Adjust the screw drive or chain so that the door opens and closes properly.

  7. Plug in or connect the door opener to the electrical outlet. Connect any new remote control switches and motion detectors that come with your new opener. Operate the door to make sure it's operating smoothly. Make any adjustments according to directions for your specific opener.
