How to Adjust the Opening & Closing Limits Adjustment of a Garage Door

Automatic garage door openers are not only convenient, but safe. You may remain in the locked comfort of your automobile while you press the button on a transmitter that either opens or closes your door. A garage door opener is a mechanical device that may require occasional adjustments to continue working properly. If your garage door does not fully open or close, or the door reverses unintentionally when you try to close it, the up and down travel limits probably need to be adjusted on the automatic opener.

  Turn the up adjustment screw one turn in a clockwise direction with a flat blade screwdriver if the door opens -- but not all of the way. Test the operation of the door. Fine-tune the adjustment by turning the screw slightly, if necessary. Repeat until the door opens all the way.
