Press the remote control push button to close the door. The door MUST reverse when it makes contact with the board. If the door stops but does not reverse: 1.

Open the door. Place an obstruction in the path of the door. 2. Press the remote control push button to close the door. The door will not move more than an inch (2.5 cm). The garage door opener will not close from a remote control if the LED in either safety reversing sensor is off (alerting you to the fact that the sensor is misaligned or obstructed). If the garage door opener closes the door when the safety reversing sensor is obstructed (and the sensors are no more than 6 inches [15 cm] above the floor), call for a trained door systems technician.

When the door reaches the fully closed position, the power door lock should automatically activate to secure the door.
