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

unit then refer to the

Diagnostic Chart

following page.

2. My remotes will not activate the door:

• Verify your door control is not blinking. If it is

blinking, deactivate the Lock Mode following the
instructions for

Using the Wall Mounted Door

Control.

instructions. Refer to

Programming

diagnostic LED for flashes on motor unit then
refer to

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.

turning down limit adjustment screw clockwise.

• 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.

turns. This relieves the tension.

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.
