Photo eyes out of alignment
Typically,
if the door starts down then
reverses, either the photo eyes
are out of alignment or there is
something blocking their view of
one another.
Check each sensor for a steady
glowing indicator light. If both
indicator lights are on, or if
one indicator light is
flickering, the sensors may be
slightly misaligned or
obstructed. When the beam is
blocked, the indicator light on
one of the two sensors will
temporarily go out. Clear any
obstruction from between the
safety sensors. (ie leaves,
trash, cobwebs or dirt on the
lens of the sensor). Adjust the
sensor until the green indicator
light is bright and steady.
Or
if an indicator light is out on
one or both sensors, check for a
possible loose or shorted wire.
Until the
problem is resolved, the
operator will override this
safety feature by applying
constant pressure to the wall
button in order to close the
door.
This
will not interfere with opening
the door.
Please refer to your owner’s
manual for additional
information or
contact us to set
up a service call if necessary.
Adjusting Force
The force adjustments control
the pressure used to open and
close the door. A new garage
door opener from the factory is
set to the lowest possible force
adjustment. If you have a
properly-balanced door, the
forces required to open and
close the door should be
minimal.
|
The force adjustments
are labeled with an
arrow indicating open or
close and numbered 1 to
9, with one being the
lowest force and nine
the highest. Please
remember that too much
force will interfere
with the proper
operation of the safety
reversal system.
Do not increase the
force beyond the minimum
amount required to close
the door.
Make these adjustments
with caution, there may
be other factors
preventing your door
from not working
properly.
Do not use the force
adjustments to
compensate for a
sticking, binding, or
unbalanced garage door.
Please
refer to your owner’s
manual for additional
information or
contact
us to set up a service
call if necessary.

Adjusting
travel/limits
The
limit adjustments
control how far the door
travels up and down when
it is connected to the
operator.
These controls
are either on the side
or end panel of your
garage door opener.
Increasing the
down travel allows the
motor to run longer,
moving the trolley
farther down the rail,
and consequently
lowering the door onto
the floor. Decreasing
the down acts in
reverse. The more you
decrease, the less time
the motor runs,
therefore stopping the
trolley and the door
before it completely
closes.
This same principle
applies to the up travel
adjustment.
One complete turn
of the adjustment screw
is equivalent to
approximately 2 inches
of travel and turning
the adjustment screw the
direction of the arrow
always increases travel.
Turning it the opposite
of the arrow decreases
travel.

Broken Spring
If your
door does not operate or is
operating very slowly and with
much difficulty, you may have a
broken spring.
You
can visually inspect your spring
to see if it is broken.
A
torsion spring is typically
mounted above the front of the
door.
There will be a visible break in
the spring.
An
extension spring is mounted
along the sides of the door
track.
There will also be a visible
break in the spring.
Regardless
of which type of spring you
have, we do not recommend you
attempt to service your own
spring system without the proper
tools or training required to do
so.
Please
contact
us to set up a service call.
Power outage/emergency
release
Every operator has an emergency
release to allow manual
operation in the event of a
power outage or operator
failure.
Refer to your user manual
on how to disengage and reengage
your model.
Please refer
to your owner’s manual for
additional information or
contact us to set up a service
call if necessary.
