Test the Safety Reversal System
2.2 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 and does not reverse
on the obstruction, the travel needs to be
adjusted (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.
Without a properly installed safety
reversal system, persons (particularly
small children) could be SERIOUSLY
INJURED or KILLED by a closing
garage door.

3.1 Open the door. Place the garage
door opener carton 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 fl oor), call
for a trained door systems technician.
Without a properly installed safety
reversing sensor, persons (particularly
small children) could be SERIOUSLY
INJURED or KILLED by a closing
garage door.
