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

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.
Troubleshooting
If after installing the new travel module, the garage door opener will not move more than 6 - 8 inches (15-20 cm), ensure you have installed the E-clip and the travel module wire harness is securely
plugged in.
2.1 With the door fully open, place a 1-1/2
inch (3.8 cm) board (or a 2x4 laid fl at)
on the fl oor, centered under the garage
door.
®
3.1 Open the door. Place the garage door
opener carton in the path of the door.
2.2 Press the remote control push button to
close the door. The door MUST reverse
when it makes contact with the board.
3.2 Press the remote control push button
to close the door. The door will not
move more than an inch (2.5 cm), and
the garage door opener lights will fl ash
10 times.

If the door stops and does not reverse on the
obstruction, increase the down travel (refer to
Adjustment Step 1).
Repeat the test. When the door reverses upon
contact with the 1-1/2 inch board, remove the
board and open/close the door 3 or 4 times to
test the adjustment.
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 fl oor), call for a trained door systems
technician.
