HAVING A PROBLEM?
1. My door will not close and the light bulbs blink on

my motor unit: The safety reversing sensor must be

connected and aligned correctly before the garage

door opener will move in the down direction.

aligned and free of any obstructions. Refer to

Installation Step 10: Install The Protector System®.

Bell Wire

then refer to the Diagnostic Chart on the following

page.

3. My door reverses for no apparent reason: Repeat

safety reverse test after adjustments to force or travel

limits. The need for occasional adjustment for the force

and limit settings is normal. Weather conditions in

particular can affect door travel.

problems.

closing and touching the floor: Repeat safety

reverse test after adjustments to force or travel limits.

DOWN Travel Limits. Decrease down travel by

turning down limit adjustment screw clockwise.

5. My lights will not turn off when door is open:

• The garage door opener is equipped with a security

light feature. This feature activates the light on when

the safety sensor beam has been obstructed. Refer

•First verify that the trolley is against the stop bolt.

•Release the door from the opener by pulling the Emergency Release Rope.

•Manually bring the door to a closed position.

•Loosen the belt by adjusting the outer nut 4 to 5 turns. This relieves the tension.

•Run the motor unit from the remote control or door control. The trolley should travel towards the door and stop. If the trolley re-engages with the door, pull the Emergency Release Rope to disengage.

•Decrease the UP travel by turning the UP Travel adjustment screw 2 full turns away from the arrow.
