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 fl ashes 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 fl ashes 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 fl oor:
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. Refer to Operation section; Using the
Wall-Mounted Door Control, Light Feature.
6. My motor unit hums briefl y:
• 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.
