Test the Protector System

Without a properly installed safety reversing
sensor, persons (particularly small children) could
be SERIOUSLY INJURED or KILLED by a closing
garage door.
3.1 With the door fully open, place a 1-1/2
inch (3.8 cm) board (or a 2x4 laid flat)
on the floor, centered under the garage
door.
®
4.1 Open the door. Place an obstruction in
the path of the door.
3.2 Press the remote control push button
to close the door. The door MUST
reverse when it makes contact with the
board.
4.2 Press the remote control push button
to close the door. The door will not
move more than an inch (2.5 cm).

If the door stops but does not reverse:
1. Repeat Program the Travel (see Adjustment Step
1);
2. Repeat the Safety Reversal test.
If the test continues to fail, call a trained door systems
technician.
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.
