4.1 Open the door. Place an obstruction in
the path of the door.
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.

a closing garage door.
