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.

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, 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.

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
