OPERATION

TESTING THE AUTOMATIC REVERSAL

SYSTEM

See Figure 66.

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,

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 button 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 DOWN button to lower the garage

door.

When the door strikes the board, it should reverse

direction immediately.

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 technician for

assistance.
