Test the Safety Reverse System

 

Test:

•Place a one-inchboard (or a 2x4 laid flat) on the floor, centered under the garage door.

•Operate the door in the down direction. The door must reverse on striking the obstruction.

Adjustment:

If the door stopson the obstruction, it is not traveling far enough in the down direction.

•Increase the DOWN limit by turning the DOWN limit adjustment screw counterclockwise 1/4 turn.

•Repeat the test.

On a sectional door, make sure limit

adjustments do not force the door arm beyond a straight up and down position. See the illustration on page 26.

•When the door reverses on the one-inch board, remove the obstruction and run the opener through 3 or 4 complete travel cycles to test adjustment.

If the door will not reverse after repeated adjustment attempts, call for professional garage door service.
