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.

• Verify the safety sensors are properly installed,

aligned and free of any obstructions. Refer to

Installation Step 10: Install The Protector System®.

• Check diagnostic LED for flashes on the motor unit

then refer to the Diagnostic Chart on the following

page.

2. My remotes will not activate the door:

• Reprogram remotes following the programming

instructions. Refer to Programming.

• If remote will still not activate your door, check

diagnostic LED for flashes on motor unit then refer to

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.

• Manually check door for balance or any binding

problems.

• Refer to Adjustment Step 2, Adjust the Force.

4. My door reverses for no apparent reason after fully
closing and touching the floor: 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.

• Refer to Adjustment Step 1, Adjust the UP and 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.

6.My motor unit hums briefly:

•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 chain 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.

•Re-tighten the outer nut so the chain is a 1/4" (6 mm) above the base of the rail. (When the door is reconnected and closed, the chain will sag. This is normal.)

•If the trolley does not move away from the bolt, repeat the steps above.
