Safety Information and Precautions

WARNING

CAUTION
To avoid damage to the garage door and opener, disable
locks before installing and operating the opener. Use a
wood screw or nail to hold locks in the "open" (unlocked)
position.
Operation at other than 120V 60 Hz will cause opener
malfunction and damage.

An unbalanced garage door might not reverse when
required and someone under the door could be seriously
injured or killed.
If your garage door binds, sticks or is out of balance, call
for professional garage door service. Garage doors, door
springs, cables, pulleys, brackets, and their hardware are
under extreme tension and can cause serious injury or
death. Do not try to loosen, move or adjust them
yourself!
Ropes left on a garage door could cause someone to
become entangled and killed. Remove all ropes
connected to the door before installing and operating the
opener.

Installation Step 1

WARNING

Determine Header Bracket Location

If the header bracket is not rigidly fastened to a
structural support on the header wall or ceiling, the
safety reverse system may not work properly (see page
26). The door might not reverse when required, and
could cause serious injury or death.
The garage door springs, cables, pulleys, brackets and
their hardware are under extreme tension. Do not attempt
to loosen, move or adjust them yourself. Serious
personal injury or death could result. Call for
professional garage door service.

Installation procedures vary according to garage
door types. Follow the instructions which apply to
your door.

The Protector System®
Information you'll need before you begin the installation of the safety reversing sensor
The safety reversing sensor must be connected and
aligned correctly before the garage door opener will
move in the down direction. This is a required safety
device and cannot be disabled.

WARNING
Without a properly working safety reversing sensor,
persons (particularly children) could be injured or killed
by a closing garage door. Read and follow all
instructions.
To protect small children, install the safety reversing
sensor so that the beam will be no higher than 4"-6"
above the garage floor.
Disconnect power to the garage door opener before
installing the safety reversing sensor.

Installation procedures are the same for sectional and
one-piece doors.
Be sure power to the opener is disconnected.
The sending eye transmits an invisible light beam to the
receiving eye. The units can be installed on either side of
the garage door as long as the sun never shines directly
into the receiving eye lens.
Look at the label on the connector end of each case to
identify the sensors.
The brackets must be connected and fastened so that the
sending and receiving eyes face each other as shown.
If an obstruction breaks the light beam while the garage
door is closing, the door will stop and reverse to full open
position and the opener lights will flash for 5 seconds.
The brackets must be securely fastened to a solid surface
such as the studs on either side of the door, or add a piece
of wood at each location if installing in masonry
construction.
The invisible light beam path must be unobstructed. No
part of the garage door (or door tracks, springs, hinges,
rollers or other hardware) can interrupt the beam while
the door is closing. If it does, use a piece of wood to build
out each sensor mounting location to the minimum depth
required for light beam clearance.

of children and away from all moving parts of the door
and door hardware, but where the garage door is visible.
Do not allow children to operate the push button(s) or the
remote control transmitter(s).
A moving garage door could injure someone under it.
Activate the opener only when the door is properly
adjusted, you can see it clearly, and there are no
obstructions to door travel.

Install Door Control
Locate the door control within sight of the door at a
minimum height of 5 feet where small children cannot
reach, and away from all moving parts of the door and
door hardware.
1. Strip 1/4" of insulation from one end of the bell wire
and connect it to the two screw terminals on the back
of the door control by color: white to 2 and white/red
to 1 (see Figure 1).
2. Fasten the Multi-Function Door Control uses
6ABx1-1/4" screws. If installing into drywall, drill
5/32" holes and use the anchors provided.
3. Run the bell wire up the wall and across the ceiling to
the opener. Use insulated staples to secure the wire in
several places. Be careful not to pierce the wire with a
staple, creating a short. If your access door is near the
garage door, you may run this wire with the Safety
Reversing Sensor wires along the top of the rail. See
page 14.
4. Remove the Control Center door on the right panel of
the opener to access the terminal screws.
Connect Door Control and Sensor Wiring
5. Thread all wires through the opening at the base of the
drive shaft cover (see Figure 2).
6. Insert the remaining wire through the hole in the power
unit and strip 1/4" of insulation from each set of wires.
7. Connect the door control wire to the opener terminal
screws: white to 2 and white/red to 1. (See Figure 3.)
8. Separate the sensor white and white/black wires
sufficiently to connect to the opener terminal screws:
white to 2 and white/black to 3.
9. Attach the User Safety Instruction label to the wall
near the door control, and the Maintenance Instruction
label in a prominent location on the inside of the
garage door.
Page 28 explains how to operate the opener using the
door controls and the Lock & Light features available
on the Multi-Function Door Control Panel.

Do NOT connect the power and operate the opener at
this time. The trolley will travel to the full open
position but will not return to the close position
until the sensor beam is connected and properly
aligned. See Step 9 on page 18.

WARNING

Electrical Requirements

To prevent electrocution or fire, installation and wiring
must be in compliance with local electrical and building
codes.
Do NOT use an extension cord, 2-wire adapter, or change
the plug in any way to make it fit your outlet.

To reduce the risk of electric shock, your garage door
opener has a grounding type plug with a third grounding
pin. This plug will only fit into a grounding type outlet.
If the plug doesn't fit into the outlet you have, contact a
qualified electrician to install the proper outlet.
To avoid installation difficulties,
do not run the opener until Step 9 below.

If permanent wiring is required by your local code,
refer to the following procedure:

Right

Wrong

WARNING
To prevent electrocution, remove power from the
garage door opener and from the circuit you plan to
use for the permanent connection.

Permanent Wiring
Connection

To make a permanent connection through the 7/8" diam.
hole in the top of the opener (according to local code):
• Remove the opener cover screws and set the cover aside.
• Remove the attached 3-prong cord.
• Connect the black (line) wire to the screw on the brass
terminal; the white (neutral) wire to the screw on the
silver terminal; and the ground wire to the green
ground screw. The opener must be grounded.
• Reinstall the cover.

Trouble Shooting
1. If the sending eye indicator light does not glow
steadily after installation, check for:
• Electric power to the opener.
• A short in the white or white/black wires. These can
occur under staples or at screw terminal connections.
• Incorrect wiring between sensors and opener.
• An open wire (wire break).
2. If the sending eye indicator light glows steadily but
the receiving eye indicator light doesn't:
• Check alignment.
• Check for an open wire to the receiving eye.
3. If the receiving eye indicator light is dim, realign
either sensor.
NOTE: When the invisible beam path is obstructed or
misaligned while the door is closing, the door will
reverse. If the door is already open, it will not close. The
opener lights will flash 10 times. (If bulbs are not
installed, 10 clicks are audible.) See page 12.

Complete Safety Reversing Sensor
Installation

Aligning the Safety Sensors
• Plug in the opener. Green indicator lights in both the
sending and receiving eyes will glow steadily if wiring
connections and alignment are correct.
The sending eye indicator light will glow regardless of
alignment or obstruction. If the indicator light is off, dim,
or flickering in the receiving eye (and the invisible light
beam path is not obstructed), alignment is required.
• Loosen the sending eye wing nut and re-adjust, aiming
directly at the receiving eye. Lock in place.
• Loosen the receiving eye wing nut and adjust sensor
vertically and/or horizontally until it receives the
sender’s beam. When the green indicator light glows
steadily, tighten the wing nut.

CAUTION

Fasten Door Bracket

To prevent damage to steel, aluminum, fiberglass or
glass panel doors, always reinforce the inside of the door
both vertically and horizontally with an angle iron.

Follow instructions which apply to your door type
as illustrated below or on page 21.

A horizontal brace should be long enough to be secured to 2 vertical supports. A vertical brace should cover the
height of the top panel.
The illustration shows one piece of angle iron as the horizontal brace. For the vertical brace, 2 pieces of angle iron
are used to create a U-shaped support. The best solution is to check with your garage door manufacturer for an
opener installation door reinforcement kit.

Closed Door Adjustment:
Decrease DOWN Travel Limit
• Turn the DOWN limit adjustment screw clockwise
5 complete turns.
• Press the Door Control push bar or button. The trolley
will travel to the fully closed position.
• Manually close the door and lift the door arm to the
trolley. The arm should touch the trolley just ahead of
the door arm connector hole. Refer to the fully closed
trolley/door arm positions in the illustration. If the arm
is behind the connector hole, adjust the limit further.
One full turn equals 2" of trolley travel.

Connect the Door Arm to the Trolley:
• Close the door and join the curved arm to the connector hole in the trolley with the remaining clevis pin. It may be
necessary to lift the door slightly to make the connection.
• Secure with a ring fastener.
• Run the opener through a complete travel cycle. If the door has a slight "backward" slant in full open position as shown
in the illustration, decrease the UP limit until the door is parallel to the floor.

Adjustment Section: Pages 24 – 26
Adjustment Step 1

WARNING

Adjust the UP and DOWN Limits

Improper adjustment of the travel limits will interfere with
the proper operation of the safety reverse system. The
door might not reverse properly when required and could
seriously injure or kill someone under it. Test the safety
reverse system monthly, and following all adjustments to
the travel limits. See page 26.

Do not make any limit adjustments until the safety
reversing sensors are completely installed.
Limit adjustment settings regulate the points at which the
door will stop when moving up or down.
The door will stop in the up direction if anything
interferes with door travel. The door will reverse in the
down direction if anything interferes with the door travel
(including binding or unbalanced doors).
To operate the opener, press the Door Control push bar.
Run the opener through a complete travel cycle.
• Does the door open and close completely?
• Does the door stay closed and not reverse
unintentionally when fully closed?
If your door passes both of these tests, no limit
adjustments are necessary unless the reversing test fails
(see page 26).
Adjustment procedures are outlined below. Run the
opener through a complete travel cycle after each
adjustment.
Repeated operation of the opener during adjustment
procedures may cause the motor to overheat and shut off.
Simply wait 15 minutes and try again.
Read the procedures carefully before proceeding to
Adjustment Step 2. Use a screwdriver to make limit
adjustments.

How and When to Adjust the Limits
If the door does not open completely but opens at least
five feet:
Increase up travel. Turn the UP limit adjustment screw
clockwise. One turn equals 2" of travel.
If door does not open at least 5 feet: Adjust the UP
(open) force as explained in Adjustment Step 2.

If the opener reverses in fully closed position:
Decrease down travel. Turn the DOWN limit adjustment
screw clockwise. One turn equals 2" of travel.
If the door reverses when closing and there is no
visible interference to travel cycle:
If the opener lights are flashing, the Safety Reversing
Sensors are either not installed, misaligned, or obstructed.
See Troubleshooting, page 18.
Test the door for binding: Pull the manual release handle.
Manually open and close the door. If the door is binding,
call for garage door service. If the door is not binding or
unbalanced, adjust the DOWN (close) force. See
Adjustment Step 2.

If the door does not close completely:
Increase down travel. Turn the DOWN limit adjustment
screw counterclockwise. One turn equals 2" of travel.
If door still won't close completely, try lengthening the
door arm. (Page 22.)
If you have adjusted the door arm to the maximum length
and the door still will not close completely, lower the
header bracket. See Installation Step 1, pages 8/9.

Adjustment Step 2

WARNING

Adjust the Force
Too much force on the door will interfere with the proper
operation of the safety reverse system. The door might
not reverse properly when required and could seriously
injure or kill someone under it. Do not increase the force
beyond the minimum amount required to close the door.
Do not use the force adjustments to compensate for a
binding or sticking garage door. Test the safety reverse
system monthly, and following all adjustments to force
levels. See page 26.

Force adjustment controls are located on the right panel
of the opener. Force adjustment settings regulate the
amount of power required to open and close the door.
The door will stop in the up direction if anything
interferes with its travel. The door will reverse in the
down direction if anything interferes with its travel
(including binding or unbalanced doors).
If the forces are set too light, door travel may be
interrupted by nuisance reversals in the down direction
and stops in the up direction. Weather conditions can
affect the door movement, so occasional adjustment may
be needed.
The maximum force adjustment range is about 3/4 of a
complete turn. Do not force controls beyond that point.

How and When to Adjust the Forces
Test the DOWN (close) force
Grasp the door bottom when the door is about halfway
through DOWN (close) travel. The door should reverse.
Reversal halfway through down travel does not
guarantee reversal on a one-inch obstruction. See
page 26. If the door is hard to hold or doesn't reverse,
decrease the DOWN (close) force by turning the control
counterclockwise.
Make small adjustments until the door reverses normally.
After each adjustment, run the opener through a complete
cycle.

If the door doesn't open at least 5 feet:
Increase UP (Open) force by turning the control
clockwise. Make small adjustments until door opens
completely. Readjust the UP limit if necessary. After each
adjustment, run the opener through a complete travel
cycle.
If the door reverses during the down (close) cycle and
the opener lights aren't flashing:
Increase DOWN (close) force by turning the control
clockwise. Make small adjustments until the door
completes a close cycle. After each adjustment, run the
opener through a complete travel cycle. Do not increase
the force beyond the minimum amount required to
close the door.

Test the UP (open) force
Grasp the door bottom when the door is about halfway
through UP (open) travel. The door should stop. If the
door is hard to hold or doesn't stop, decrease UP (open)
force by turning the control counterclockwise.
Make small adjustments until the door stops easily. After
each adjustment, run the opener through a complete
travel cycle.

Adjustment Step 3

WARNING

Test The Protector System ®

Without a properly working safety reversing sensor,
persons (particularly children) could be seriously injured
or killed if trapped by a closing garage door. Repeat this
test once a month.

• Press the remote control push button to open the door.
• Place the opener carton in the path of the door.
• Press the remote control push button to close the door.
The door will not move more than an inch, and the
opener light will flash for 5 seconds.
Professional service is required if the opener closes the
door when the safety reversing sensor is obstructed.
The garage door opener will not close from a remote if
the indicator light in either sensor is off (alerting you
to the fact that the sensor is misaligned or obstructed).
The garage door can be closed by pressing and holding the
Door Control push bar until down travel is completed.

WARNING

Test the Safety Reverse System

Failure to test and adjust the safety reverse system may
result in serious injury or death to persons trapped by a
closing garage door. Repeat this test once a month and
adjust as needed.

Test
• Place a one-inch board (or a 2x4 laid flat) on the floor,
centered under the garage door.
• Operate the door in the down direction. The door must
reverse on striking the obstruction.
Adjustment
If the door stops on the obstruction, it is not traveling far
enough in the down direction.
• Increase the DOWN limit by turning the DOWN limit
adjustment screw counterclockwise 1/4 turn.
• Repeat the test.
On a sectional door, make sure limit adjustments do
not force the door arm beyond a straight up and down
position. See the illustration on page 22.
• When the door reverses on the one-inch board, remove
the obstruction and run the opener through 3 or 4
complete travel cycles to test adjustment.
If the door will not reverse after repeated adjustment
attempts, call for professional garage door service.

2. If closing, the door will reverse.
3. If opening, the door will stop (allowing space for entry and
exit of pets and for fresh air).
4. If the door has been stopped in a partially open position, it
will close.
5. If obstructed while closing, the door will reverse.
6. If obstructed while opening, the door will stop.
7. The garage door will reverse in the closing cycle, and the
opener lights will blink for 5 seconds, when the invisible
beam is broken. If fully open, the door will not close when
the beam is broken. The sensor has no effect in the opening
cycle.
If the sensor is not installed, or is not aligned correctly, the door
won't close from any remote transmitter. You can close the door
with the Door Control, the Outside Keylock, or Keyless Entry,
however, if you activate them until down travel is complete. If you
release them too soon, the door will reverse.
Opener Lights will turn on under the following conditions:
When the opener is initially plugged in; when the power is
interrupted; when the opener is activated. It will turn off
automatically after 4-1/2 minutes or provide constant light when
the Light feature on the Multi-Function Door Control is

WARNING
Children operating or playing with a garage door opener
can injure themselves or others. The garage door could
close and cause serious injury or death. Do not allow
children to operate the door controls or remote controls.
A moving garage door could injure or kill someone under

Having a Problem?
Situation

Probable Cause & Solution

The opener doesn't
operate from either
the door control or
the remote control:

1. Does the opener have electric power? Plug a lamp into the outlet. If it doesn't light, check the
fuse box or the circuit breaker. (Some outlets are controlled by a wall switch.)
2. Have you disabled all door locks? Review installation instruction warnings on Page 7.
3. Is there a build-up of ice or snow under the door? The door may be frozen to the ground.
Remove any restriction.
4. The garage door spring may be broken. Have it replaced.
5. Repeated operation may have tripped the overload protector in the motor. Wait 15 minutes.
Try again.

Opener operates from
the remote control, but
not from the door
control:

1. Is the door control push bar lit? If not, Remove the bell wire from the opener terminal
screws. Short the red and white terminals by touching both terminals at the same time with
a piece of wire. If the opener runs, check for a faulty wire connection at the door control, a
short under the staples, or a broken wire.
2. Are the wiring connections correct? Review Installation Step 7, page 17.

The door operates from
the door control, but not
from the remote
control:

1. Is the door push bar flashing? If your model has the Lock feature, turn it off.
2. Your opener needs to re-learn a remote control code. Refer to instructions on the opener
panel.
3. Program the receiver to match the remote control code.
4. Repeat the receiver programming procedure with all remote controls.

The remote control has
short range:

1. Change the location of the remote control in your car.
2. Check to be sure the antenna on the right side panel of opener extends fully.
3. Some installations may have shorter range due to a metal door, foil backed insulation, or
metal garage siding.

Opener noise is
disturbing in living
quarters of home:

If operational noise is a problem because of proximity of the opener to the living quarters, the
Vibration Isolator Kit 41A3263 can be installed. This kit was designed to minimize vibration
to the house and is easy to install.

The garage door
opens and closes by
itself:

1. Be sure that all remote control push buttons are off.
2. Remove the bell wire from the door control terminals and operate from the remote control
only. If this solves the problem, the door control is faulty (replace), or there is an
intermittent short on the wire between the door control and the opener.
3. Clear memory and reprogram all remote controls.

The door doesn't open
completely:

1. If the door has been working properly but now doesn't open all the way, increase the up
force. See page 25.
2. Is something obstructing the door? Remove the obstruction or repair the door.
3. If door opens at least 5 feet, the travel limits may need to be increased. One turn equals
2 inches of travel. See page 24.
Repeat the safety reverse test after the adjustment is complete.

The door stops but
doesn't close
completely:

Review the travel limits adjustment procedures on page 24.
Repeat the safety reverse test after any adjustment of door arm length, close force or down
limit.

Having a Problem? (continued)
Situation

Probable Cause & Solution

The door opens but
won't close:

1. If the opener lights blink, check the safety reversing sensor. See page 18.
2. If the opener lights do not blink and it is a new installation, check the down force. See
Adjustment Step 2, page 25. For an existing installation, see below.
Repeat the safety reverse test after the adjustment is complete.

The door reverses for no
apparent reason and
opener lights don't
blink:

1. Is something obstructing the door? Pull the manual release handle. Operate the door
manually. If it is unbalanced or binding, call for professional garage door service.
2. Clear any ice or snow from the garage floor area where the door closes.
3. Review the force adjustment procedures on page 25.
4. If door reverses in the fully closed position, decrease the travel limits (page 24).
Repeat the safety reverse test after adjustments to force or travel limits. The need for
occasional adjustment of the force and limit settings is normal. Weather conditions in
particular can affect door travel.

The door reverses for no
apparent reason and
opener lights blink for
5 seconds after
reversing:

Check the safety reversing sensor. Remove any obstruction or align the receiving eye. See
page 18.

The opener lights…

don't turn on:
Replace the light bulb(s) (100 watts maximum). Use a standard neck garage door opener bulb
if regular bulb burns out.
don't turn off:
Is the Light feature on? Turn it off.

The opener strains or
maximum force is
needed to operate door:

The door may be out of balance or the springs are broken. Close the door and use the manual
release handle to disconnect the trolley. Open and close the door manually. A properly
balanced door will stay in any point of travel while being supported entirely by its springs. If
it does not, disconnect the opener and call for professional garage door service. Do not
increase the force to operate the opener.

The opener motor
hums briefly, then
won't work:

1. The garage door springs are broken. See above.
2. If the problem occurs on the first operation of the opener, door may be locked. Disable the
door lock.
Repeat the safety reverse test after the adjustment is complete.

The opener won't
operate due to power
failure:

1. Use the manual release handle to disconnect the trolley. The door can be opened and closed
manually. When power is restored, press the Door Control push bar or button and trolley
will automatically reconnect (unless trolley is in lockout position.) See page 28.
2. The Outside Quick Release accessory (for use on garages with no service door) disconnects
the trolley from outside the garage in case of power failure.
