Adjustment Step 3

Test The Safety Reversing Sensor

•Press the remote control push button to open the door.

•Place the opener carton in the path of the door.

•Press the remote control push button to close the door. The door will not move more than an inch, and the opener light(s) will flash.

Professional service is required if the opener closes the door when the safety reversing sensor is obstructed.

The garage door opener will not close from a remote control if the indicator light in either sensor is off(alerting you to the fact that the sensor is misaligned or obstructed).

The garage door can be closed by pressing and holding the Wall Control push bar until down travel is completed.

Without a properly working safety reversing sensor, persons (particularly children) could be seriously injured or killed if trapped by a closing garage door. Repeat this test once a month,

Adjustment Step 4

Test the Safety Reverse System

Test:

•Place a one-inch board (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 stops on 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.

Failure to test and adjust the safety reverse system may result in serious injury or death to persons trapped by a closing garage door.

Repeat this test once a month and adjust as needed.
