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.
l
Refer to Installation Step 13: Install The Protector System®.
Check diagnostic LED for flashes on the motor unit then refer to the Diagnostic Chart on the
l
following page.
2. My remotes will not activate the door:
Verify your Multi-Function Door Control is not blinking. If it is blinking, deactivate the Lock Mode
l
following the instructions for Using the Multi-Function Door Control.
Reprogram remotes following the programming instructions. Refer to Programming.
l
If remote will still not activate your door, check diagnostic LED for flashes on motor unit then
l
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

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
l
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
l
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 briefly:
First verify that the trolley is against the stop bolt.
l
Release the door from the opener by pulling the Emergency Release Rope.
l
Manually bring the door to a closed position.
l
Loosen the chain by adjusting the outer nut 4 to 5 turns. This relieves the tension.
l
Run the motor unit from the remote control or door control. The trolley should travel towards
l
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
l
arrow.
Re-tighten the outer nut so the chain is a 1/4" (6 mm) above the base of the rail. (When the
l
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.
