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.
Identify the type and height of your door, any special
conditions that exist, and any additional materials that
may be required by referring to the list on page 4.
This product is for use on sectional garage
doors only. Serious personal injury could
result from the use of this product on
one-piece garage doors.
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.

center bearing plate in the way of the header bracket
or door bracket area. If your door has extension
springs, the opener must be installed in the center of
the door. See pages 11 and 22.
• Look at the garage door where it meets the floor. It
must close on the floor all the way across. Other-
wise, the safety reverse system may not work
properly. Floor or door should be repaired. See
page 26.
Do you have an access door in addition to the garage
door? If not, Model 53702 Emergency Key Release is
required. See page 34.

Installation Step 6
Install the Door Control
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.
Install the Door Control (or any additional push
buttons) out of the reach 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 or the remote controls.
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 door control is typically attached directly to the
wall. If installing into drywall, drill 5/32" holes and use
the anchors provided.
• 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: white to 2, and
white/red to 1.
• Fasten the Door Control securely with
6ABx1-1/2" screws.
• 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, thereby resulting in a short.
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 Safety Reversing Sensor Instructions
beginnning on page 19.
• Receiver terminal screws and the antenna are
located on the back panel of the opener. Position
the antenna wire as shown.
• Then connect the bell wire to the opener terminal
screws: white to 2 and white/red to 1.
• Remember to affix 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.
Hardware Shown Actual Size
If the label adhesive will not adhere to your garage
wall surface (or becomes loose with time), use tacks
to secure the label alongside the Door Control.

Electrical Requirements
WARNING
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 at this time.
Right
Wrong
If permanent wiring is required by your local code, refer to the following procedure:
WARNING
To prevent electrocution, remove power from
the garage door opener and from the circuit
you plan to use for the permanent
connection.
To make a permanent connection through the 7/8"
diameter hole in the top of the opener (according
to local code):
Permanent wiring
connection
• 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.

Safety Reversing 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 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.
Be sure power to the opener is disconnected.
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 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.
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.
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 below in Figure 1.
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 light will
flash for 5 seconds.

Trouble Shooting
• 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.
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).
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.
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 light will flash 10 times. (If bulb is not
installed, 10 clicks are audible.) See page 19.
• 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
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.
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.

Adjustment Step 1
Adjust the UP and DOWN Limits
Do not make any limit adjustments until the
safety reversing sensors are completely
installed.
WARNING
Improper adjustment of the travel limits could
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 limtis. See page 26.
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
button. Run the opener through a complete travel
cycle.

Adjustment Label
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 you have adjusted the door arm to the maximum
length and the door still will not close completely,
lower the header bracket. See Installation Steps 1
and 2, pages 11 and 12.
• If the opener reverses in fully closed position:
NOTE: To prevent the trolley from hitting the
cover protection bolt, keep a minimum distance
of 2-4" between the trolley and the bolt.
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:
• If the door reverses when closing and there is
no visible interference to travel cycle:
Adjust the UP (open) force as explained in
Adjustment Step 2.
If the opener light is flashing, the Safety Reversing
Sensors are either not installed, misaligned, or
obstructed. See Troubleshooting, page 21.
Test the door for binding: Pull the emergency 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 and the trolley
bumps into the pulley bracket (see page 4), try
lengthening the door arm. (See page 23.)
24
Adjustment Step 2
Adjust the Force
WARNING
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 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 26.
Force adjustment controls are located on the back
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.
Force Adjustment
Controls
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
Test the DOWN (close) force:
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.
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.
If the door reverses during the down (close) cycle
and the opener light iswn't flashing:
Make 10 degree turn adjustments until the door
reverses normally. After each adjustment, run the
opener through a complete cycle.
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.

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.
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.
Make sure limit adjustments do not force the
door arm beyond a straight up and down
position. See the illustration on page 23.
• When the door reverses on the one-inch object
(or 2x4 laid flat), remove the obstruction and run
the opener through 3 or 4 complete travel cycles to
test adjustment.
One-inch Board

To Add the Keyless Entry
We recommend that you program your code before
you install the Keyless Entry. You will not need
assistance, and you can test the reception at the
mounting location before installation.
If you decide to use a different remote control button
than originally programmed into the opener, you
need to erase all the learned codes and reprogram
each remote control used to operate the garage door
opener.
1. Choose a 4-digit code using numbers from 0 to 9.
You can use a number more than once (for
example, 4, 0, 4, 1). Press the selected code digits
on the keypad.
To Erase All Remote Control Codes
• Press and hold the “SRT” button on the opener
panel until the indicator light turns off (about
6 seconds). All the codes the opener has learned
will be erased.
2. Press and hold the Enter button while you press
the “SRT” (learn) button on the opener panel. The
indicator light will blink and the door will begin to
move.
• To reprogram, repeat Steps 1-3 for each remote
control in use.
3. Release the Enter button. Now the opener has
learned the selected keypad code.
To ensure that your portable remote control codes
were not disturbed while you were programming the
Keyless Entry, test your remotes and reprogram
them if necessary.
Code programming instructions are also located
on the opener panel.
To change the code at any time, repeat Steps 1-3.

Having a Problem?
Situation
Probable Cause & Solution
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 10.
The opener doesn't
operate from either
the door control or
the remote control:
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 button 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 16.
The door operates
from the door control,
but not from the
1. Does the battery test light glow when the remote control push button is pressed? If
not, replace the battery.
2. Your opener needs to re-learn a remote control code. Refer to Instructions on the
opener panel.
remote control:
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. Check the battery test light. If the light is dim, change the battery.
2. Change the location of the remote control in your car.
3. Check to be sure the antenna on the back panel of opener extends fully downward.
4. Some installations may have shorter range due to a metal door, foil backed
insulation, or metal garage siding.
Install Antenna Kit, Part No. 41A3504, to increase range.
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.
1. Be sure that all remote control push buttons and battery indicator lights are off.
The garage door
opens and closes
by itself:
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.
30
Having a Problem? (continued)
Situation
Probable Cause & Solution
The door opens but
won't close:
1. If the opener light blinks, check the safety reversing sensor. See page 21.
2. If the opener light does 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 light
doesn't blink:
1. Is something obstructing the door? Pull the emergency 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 safety reverse test after the adjustment is complete. The need for
occasional adjustment of the force and limit settings is normal. Weather
conditions in particular can affect door travel.
Check the safety reversing sensor. Remove any obstruction or align the receiving eye.
See page 21.
The door reverses for
no apparent reason
and opener light
blinks for 5 seconds
after reversing:
The opener light
. . . doesn't turn on:
Replace the light bulb (75 watts maximum). Use a standard neck garage door opener
bulb if regular bulb burns out.
. . . doesn't turn off:
There may be a defective ground at the ceiling or wall receptacle. The unit must be
grounded.
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
emergency 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. If the chain was removed and re-installed, the motor may be out of phase.
Remove the chain; 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 chain.
Repeat the safety reverse test after the adjustment is complete.
1. Use the emergency release rope and handle to disconnect the trolley. The door can
be opened and closed manually. When power is restored, press the door control
button and trolley will automatically reconnect (unless trolley is in lockout position.)
See page 28.
The opener won't
operate due to
power failure:
2. The Emergency Key Release accessory (for use on garages with no service door)
disconnects the trolley from outside the garage in case of power failure.
The chain droops
or sags:
It is normal for the chain to droop slightly in the closed door position. Use the
emergency release rope and handle to disconnect the trolley. If the chain returns to the
normal height when the trolley is disengaged and the door reverses on a
one-inch board (or a 2x4 laid flat), no adjustments are needed. (See page 10.)
