WARNING
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.
Before you begin, complete the following test to
make sure your door is balanced, and is not
sticking or binding:
• Lift the door about halfway as shown. Release the
door. It should stay in place, supported entirely by
its springs.
• Raise and lower the door to see if there is any
binding or sticking.
Identify the type and height of your door and any
special conditions that exist and any additional
materials that may be required.

IMPORTANT INSTALLATION INSTRUCTIONS
WARNING
WARNING
To reduce the risk of severe injury or death to persons:
1.
READ AND FOLLOW ALL INSTALLATION INSTRUCTIONS.
2. Install only on a properly balanced and lubricated garage door. An improperly balanced door
may not reverse and could result in severe injury or death. Repairs to cables, spring assemblies
and other hardware must be made by a professional service person before installing opener.
3. Disable all locks and remove all ropes connected to the garage door before installing the opener.
Ropes connected to a garage door can cause entanglement and death.
4. If possible, install door opener 7 feet or more above floor with the manual release handle
mounted 6 feet above the floor.
5. Do not connect the opener to power source until instructed to do so.
6. 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.
7. Install the User Safety Instruction Label on the wall adjacent to the control button and the
Maintenance Instruction Label in a prominent location on the inside of the garage door.
8. Upon completion of the installation, the door must reverse when it comes in contact with a
one-inch high object (or a 2x4 laid flat) on the floor.
9. Do not wear watches, rings or loose clothing while installing or servicing an opener. Jewelry or
loose clothing can be caught in the mechanism of the garage door or 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 30). 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.

Remember, you can fasten the header
bracket within 4 feet to the left or right
of the door center only if a torsion
spring or center bearing plate is in the
way; or you can attach it to the ceiling
(refer to page 14) when clearance is
minimal. (It may be mounted on the
wall upside down if necessary, to gain
approximately 1/2".)
If you need to install the header bracket

SHOCK, BURN OR ELECTROCUTION.
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 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.
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.
The multi-function door control is typically attached
directly to the wall. For pre-wired installations (as in
new home construction) it can be mounted to a
standard single gang box. See illustrations.
• Strip 1/4" of insulation from one end of the bell wire.
Connect the wire to the two screw terminals on the
back of the door control as follows: white wire to 2
and white/red wire to 1. (NOTE: After installation, a
green indicator light behind the white translucent
cover will indicate proper connection. If not lit, the
Lock and Light features will not function (reverse
wires to correct).
• Before mounting, remove the white cover by gently
pushing both thumbs against the upper corners of
the cover on the back side of the door control (see
illustration).
• For standard wall mount, mark the wall about 1-1/4"
up the centerline from the bottom of the door control.

IMPORTANT INFORMATION ABOUT THE SAFETY
REVERSING SENSOR
WARNING
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.
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.
When properly connected and aligned, the safety
reversing sensor will detect an obstacle in the path of
its electronic beam. The sending eye (with an orange
indicator light) transmits an invisible light beam to the
receiving eye (with a green indicator light). If an
obstruction breaks the light beam while the door is
closing, the door will stop and reverse to full open
position, and the door control will flash for 5 seconds.
The units must be installed inside the garage so that
the sending and receiving eyes face each other
across the door, between 4 – 6" above the floor.
Either can be installed on the left or right of the door
as long as the sun never shines directly into the
receiving eye lens.
The mounting brackets are designed to clip onto the
track of sectional garage doors without additional
hardware.
If it is necessary to mount the units on the wall, the
brackets must be securely fastened to a solid surface
such as the wall framing. Extension brackets (see
accessories) are available if needed. If installing in
masonry construction, add a piece of wood at each
location to avoid drilling extra holes in masonry if
repositioning is necessary.
The invisible light beam path must be unobstructed.
No part of the garage door (or door tracks, springs,
hinges, rollers or other hardware) may interrupt the
beam while the door is closing.

brackets, with lenses pointing toward each other
across the door. Be sure the lens is not obstructed
by a bracket extension. See Figure 5.
• Finger tighten the wing nuts.
• Run the wires from both sensors to the opener. Use
insulated staples to secure wire to wall and ceiling.
• Strip 1/4" of insulation from each set of wires.
Separate white and white/black wires sufficiently to
connect to the opener terminal screws: white to 2
and white/black to 3.

TROUBLESHOOTING THE SAFETY SENSORS
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 at staples, or at screw terminal
connections.
• Incorrect wiring between sensors and opener.
• A broken wire.
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 door control will blink 10 times. See page 21.
ALIGNING THE SAFETY SENSORS
• Plug in the opener. The indicator lights in both the
sending and receiving eyes will glow steadily if
wiring connections and alignment are correct.
The sending eye orange indicator light will glow
regardless of alignment or obstruction. If the green
indicator light in the receiving eye is off, dim, or
flickering (and the invisible light beam path is not
obstructed), alignment is required.
• Loosen the sending eye wing nut and readjust,
aiming directly at the receiving eye. Lock in place.
• Loosen the receiving eye wing nut and adjust
sensor 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 25.
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.

• Turn the UP limit adjustment screw counterclockwise 5-1/2 turns.
• Press the Door Control push bar. The trolley will
travel to the fully open position.
• Manually raise the door to the open position
(parallel to the floor), and lift the door arm to the
trolley. The arm should touch the trolley just in
back of the door arm connector hole. Refer to the
fully open trolley/door arm positions in the
illustration. If the arm does not extend far enough,
adjust the limit further. One full turn equals 2" of
trolley travel.
Closed Door Adjustment:
Decrease DOWN limit
• Turn the DOWN limit adjustment screw clockwise
5 complete turns.
• Press the Door Control push bar. 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 28 – 30
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 following all
adjustments to the travel limits. See page 30.
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 30).

NOTE: To prevent the trolley from hitting the
cover protection bolt, keep a minimum distance
of 2-4" between the trolley and the bolt.
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 12 and 13.
• 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 door does not open at least 5 feet:
Adjust the UP (open) force as explained in
Adjustment Step 2.
• 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 23.
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 the door still won't close completely and the trolley
bumps into the pulley bracket (see page 4 or 5), try
lengthening the door arm (see page 26).
28
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 following all adjustments to force
levels. See page 30.
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 260
degrees, about 3/4 of a complete turn. Do not force
controls beyond that point. Turn force adjustment
controls with a screwdriver.

How and When to Adjust the Forces
If the door doesn't open at least 5 feet
Increase UP (Open) force by turning the control
clockwise. Make 10 degree turn adjustments until
door opens completely. Re-adjust the UP limit if
necessary. After each adjustment, run the opener
through a complete travel cycle.
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 30. If the door is hard to
hold or doesn't reverse, decrease the DOWN (close)
force by turning the control counterclockwise.
Make 10 degree turn adjustments until the door
reverses normally. After each adjustment, run the
opener through a complete 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 10 degree turn 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 10 degree turn adjustments until the door
stops easily. After each adjustment, run the opener
through a complete travel cycle.
29
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 lights will flash.
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.
Safety Reversing Sensor
Adjustment Step 4
Safety Reversing Sensor
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:
• With the door fully open, 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 26.
• When the door reverses on the one-inch board (or
a 2x4 laid flat), 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.
GARAGE DOOR
One-Inch Board
(or a 2x4 Laid Flat)
Important safety check:
Repeat Adjustment Steps 1, 2 and 4 after:
• Each adjustment of door arm length, force controls
or limit controls.
• Any repair to or adjustment of the garage door
(including springs and hardware).
• Any repair to or buckling of the garage floor.
• Any repair to or adjustment of the opener.

IMPORTANT SAFETY INSTRUCTIONS
WARNING
WARNING
To reduce the risk of severe injury or death to persons:
1. READ AND FOLLOW ALL INSTRUCTIONS.
2. Do not permit children either to operate or to play with the opener. Keep remote control in a location
inaccessible to children.
3. Operate opener only when the door is in full view and free from any obstruction. Keep the door in
sight until it is completely closed. NO ONE SHOULD CROSS THE PATH OF THE MOVING DOOR.
4. Check safety reversal system monthly. See page 30. The garage door MUST reverse on contact with
a one-inch object (or a 2x4 board laid flat) placed on the floor. If an adjustment is made to either the
force or limit of travel, both adjustments may be needed and the safety reversal system must be
checked. Failure to properly adjust the opener may result in severe injury or death.
5. If possible, use the manual release only when the door is in a closed position. Caution should be
taken whenever the disconnect cord is actuated with the door open. Weak or broken springs may
cause the door to fall rapidly, causing injury or death to persons.
6. KEEP GARAGE DOORS PROPERLY BALANCED. See page 3. An improperly balanced door may not
reverse when required and could result in severe injury or death. Repairs to cables, spring assemblies
and other hardware must be made by a professional garage door person.
7. Disconnect the electric power to the garage door opener before making any repairs or removing the
covers.

Operation of Your Opener
Activate the opener with any of the following:
• The Remote Control Transmitter. Hold push
button down until the door starts to move.
• The Door Control. Hold push bar down until the
door starts to move.
• The Outside Keylock or Keyless Entry.
(See Accessories)
When the opener is activated with the Safety
Reversing Sensor installed and correctly aligned:
1. If open, the door will close. If closed, it will open.
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
control 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.
The 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 activated.
Bulb size is 75 watts maximum.
Lights will also turn on when someone walks through
the open garage door. With a Multi-Function Door
Control, this feature may be turned off as follows: With
the opener lights off, press and hold the light button for
10 seconds, until the light goes on and off again. To
restore this feature, start with the opener lights on,
then press and hold the light button for 10 seconds.

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 11.
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 remote control,
but not from 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 Step 6, page 18.
The door operates
from the door control,
but not from the
remote control:
1. Is the door push bar flashing? If the Lock button is on, 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 side or back panel of the opener extends fully
downward.
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. Is something obstructing the door? Remove the obstruction or repair the door.
2. If the door has been working properly but now doesn't open all the way, increase the
up force. See page 29.
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 28.
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 28.
Repeat the safety reverse test after any adjustment of door arm length, close
force or down limit.
34
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 23
2. If the opener lights do not blink and it is a new installation, check the down force.
See Adjustment Step 2, page 29. 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 29.
4. If door reverses in the fully closed position, decrease the travel limits (page 28).
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 light(s)
blink for 5 seconds
after reversing:
Check the safety reversing sensor. Remove the obstruction or align the receiving eye.
See page 23.
The opener lights…
don't turn on:
Replace the light bulbs (75 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
the door:
The door may be out of balance or the springs are broken. Close the door and use the
manual release rope and 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. If the belt was removed and reinstalled, the motor may be out
of phase. Remove the belt; cycle the motor to the down position. Observe the drive
sprocket. When it turns in a clockwise direction and stops in the down position,
reinstall the belt.
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 the power is restored, press the Door Control and trolley
will automatically reconnect (unless trolley is in the lockout position, see page 32).
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.

Enables homeowner to operate garage door opener from outside by
entering a password on a specially designed keyboard. Also can add a
temporary password for visitors or service persons. This temporary
password can be limited to a programmable number of hours or entries.
This allows authorized persons a way to gain temporary

accesses, this temporary password expires and will no
longer open the door. The temporary password can be used
to close the door even after it has expired. To set a

button.
2. Press the temporary 4-digit password you have chosen,
then press Enter.

number can be used more than once, for example, 4, 0,
4, 1).

hold the Enter button. The indicator light on the door
opener panel will blink.
