TESTING THE AUTOMATIC REVERSAL
SYSTEM
See Figure 80.
DANGER:
Test the automatic reversal system every month and
after any adjustments are made to the garage door travel
limits. If the door contacts an object higher than 1-1/2 in.
off the garage floor (approx. the size of a 2x4 laid flat), it
should stop and reverse to the fully open position. If the
automatic reversal system does not function properly, a
closing garage door could kill or seriously injure someone
in its path.
WARNING:
DO NOT operate the garage door opener unless the
automatic reversal system is working correctly. Following
this rule will reduce the risk of death or serious personal
injury.
Press and release the UP/DOWN button on the indoor
keypad to raise the garage door.
Place a 1-1/2 in. board ( approx. the size of a 2x4 laid flat)
on the garage floor beneath the door .
Press and release the UP/DOWN button on the indoor
keypad to lower the garage door. When the door strikes
the board, it should reverse direction immediately.
NOTE: After the door contacts the board, a buzzer will
sound five times and the garage door opener’s LED lights
blink five times.
If the garage door reverses direction after contacting the
board, the reversal system is working properly and no
adjustments are needed.
If the garage door stops before striking the board or
strikes the board and then stops, increase the travel limit
for the closed position and repeat the test.
If the automatic reversal system continues to fail, contact
customer service or a qualified service person for
assistance.
