How to Adjust a Garage Door Opener

The key to maintaining the proper and safe operation of your garage door is keeping it in adjustment. Most standard openers adjust in similar ways, but make sure to check your owner’s manual before trying any of these adjustments. garage-door-opener-installation-7

Up/down Limits
With the door in a closed position, press the open button. If the door does not open completely but opens at least 5 feet, the limit-adjustment screw needs to be turned clockwise. If the door closes partially but not completely, the down-adjustment screw needs to be turned counterclockwise.

Garage Door Force
If the door reverses when it is closing, first check to make sure that the sensors are not being blocked by anything; if not, increase the down force. If the door does not open at least 5 feet, increase the up force.

Safety Reverse
All garage door openers today come with a safety reverse feature to prevent harm to people, pets, and objects that may be in the way when the door is closing. To test this feature, place a 2 by 4 across the garage door’s threshold. Press the close button; if the door stops but does not ascend immediately, turn the screw on the down limit clockwise by one-quarter. Then test the safety reverse system again.
