Test the Safety Reversal System
Without a properly installed safety reversal
system, persons (particularly small children)
could be SERIOUSLY INJURED or KILLED by a
closing garage door.
• Safety reversal system MUST be tested
every month.
• After ANY adjustments are made, the
safety reversal system MUST be tested.
Door MUST reverse on contact with 1-1/2"
high (3.8 cm) object (or 2x4 laid flat) on the
floor.

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.
