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 reversing 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 reversing 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
1/2" (13 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.
