How do I make force adjustments? The force adjustments control the pressure used to open and close the door. A new garage door opener from the factory is set to the lowest possible force adjustment. If you have a properly-balanced door, the forces required to open and close the door should be minimal. The force adjustments are usually located on the rear of the garage door opener and/or under one of the light lenses, if your opener has two lights. If you have lights on the side of your opener, the force adjustment will be located under the right light lens. The force adjustments are labeled with an arrow indicating open or close and numbered 1 to 9, with one being the lowest force and nine the highest. The force adjustments can only turn 260 degrees, or ¾ of a complete turn. Changes to the forces should be done in 10-degree increments. Please remember that too much force will interfere with the proper operation of the safety reversal system. Do not increase the force beyond the minimum amount required to close the door. Do not use the force adjustments to compensate for a sticking, binding, or unbalanced garage door. After adjusting the opener, always test the safety reverse system. We recommend repeating this test monthly. Place a one inch board (or 2 x 4 laid flat) on the floor, centered under the garage door. Operate the door in the down direction. The door must reverse upon striking the board. If it does not, refer to your owner“s manual, call your local LiftMaster Authorized Dealer or speak to one of our technical service representatives by calling our S.O.S. HotLine® at 1-800-528-5880. Failure to pass the above test could result in serious injury or death.
