SECTIONAL DOOR

ONE-PIECE DOOR

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.

You'll Need Tools

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 and any
special conditions that exist and any additional
materials that may be required by referring to the
lists on page 4 or page 5.

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.

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 emergency 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 door control 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.

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.

For pre-wired installations
(as in new home construction), Console models
may be mounted to a standard single gang box
(Figure 2).

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: white to 2 and
white/red to 1.

2. Door Control Button: Fasten securely with

6ABx1-1/2" screws.
Console Model: Pry off cover along one side

with a screwdriver blade (Figure 1). Fasten with
6ABx1-1/4" self-tapping screws (standard
installation) or 6-32x1" machine screws (pre-wired
installation) as follows:

• Install bottom screw, allowing 1/8" to protrude
above wall surface.

• Position bottom of door control on screw head
and slide down to secure. Adjust screw for snug
fit.

• Install top screw with care to avoid cracking
plastic housing.

Do not overtighten.

• Insert top tabs and snap on cover.

3.

(For standard installation only)

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.

4. Connect the bell wire to the terminal screws on
the opener panel: white to 2; white/red to 1.

5. Position the antenna wire as shown.

Do not connect to live electrical wiring. Connect
only to 24 Volt low voltage wires. Connection to
live wires or higher voltage may cause serious
injury from 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.

Attach the Emergency
Release Rope and Handle

Do not use the red handle to pull the door
open or closed.

The rope knot could become

untied and you could fall.

Use the emergency
release only to disengage the trolley and, if
possible, only when the door is closed.

Garage doors are heavy. If the door is open
when the handle is pulled, the door could
close inadvertently if it is not properly
balanced. Serious injury may result to persons
under the door. Make sure the doorway is clear
of persons and obstructions before pulling
handle when door is open.

• Thread one end of the rope through the hole in

the top of the red handle so "NOTICE" reads right
side up as shown. Secure with an overhand knot.

The knot should be at least 1" from the end of
the rope to prevent slipping.

• Thread the other end of the rope through the hole
in the release arm of the outer trolley.

• Adjust rope length so the handle is 6 feet above
the floor. Secure with an overhand knot .

If it is necessary to cut the rope, heat seal the
cut end with a match or lighter to prevent
unraveling.

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.

Installation procedures are the same for sectional
and one-piece doors.

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.

Figure 1: Facing the door from inside the garage

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.

21

Safety Reversing System

Information you'll need before you begin the installation of the safety reversing sensor.

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 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 lights
will flash for 5 seconds.

Install the Safety Reversing Sensor

Figures 2 and 3 show assembly of brackets and
"C" wrap based on the recommended installation of
the sensors as shown on page 21.

However, Figures 4 and 5 are variations which may
fit your installation requirements better. Make sure

the wraps and brackets are aligned so the
sensors will face each other across the garage
door.

• Fasten the "C" wraps to the mounting brackets

having square holes, using the hardware shown
in Figure 2.

• Connect each assembly to a slotted bracket, using
the hardware shown in Figure 3.

Note the alignment of the brackets for left and
right sides of the door.

• Finger tighten the lock nuts.

• Use bracket mounting holes as a template to
locate and drill (2) 3/16" diameter pilot holes on
both sides of the garage door, 4"-6" above the
floor

but not exceeding 6".

(See warning on

page 21.)

• Attach bracket assemblies with 1/4"x1-1/2" lag
screws as shown in Figure 3.

• Adjust right and left side bracket assemblies to the
same distance out from the mounting surface.

• 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.

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.

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 21.

Installation Step 11

Fasten Door Bracket

Follow instructions which apply to your door
type as illustrated below or on page 25.

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.

• Center the door bracket on the previously marked
vertical guideline used for the header bracket
installation.

Note the correct UP placement, as

stamped inside the bracket.

• Position the bracket on the face of the door within
the following limits:

A) The top edge of the bracket 2"-4" below the top

edge of the door.

B) The top edge of the bracket directly below any

structural support across the top of the door.

• Mark and drill 5/16" left and right fastening holes.
Secure the bracket as shown in Figure 1 if there is
vertical reinforcement.

If your installation doesn't require vertical reinforce­ment but does need top and bottom fastening holes
for the door bracket, fasten as shown in Figure 2.

Open Door Adjustment:

Decrease UP limit

• Turn the UP limit adjustment screw counter­clockwise 5-1/2 turns.

• Press the Door Control push bar or button. 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 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.

27

Assemble the Door Arm:

• Fasten the straight and curved door arm sections

together to the longest possible length (with a 2 or
3 hole overlap).

• With the door closed, connect the straight door arm
section to the door bracket with the 5/16"x1-1/4"
clevis pin.

• Secure with a ring fastener.

On one-piece doors, before connecting the door arm to the trolley the travel limits must be adjusted. Limit adjustment
screws are located on the left side panel as shown on page 28. Follow adjustment procedures below.

Adjustment Step 1

Adjust the UP and DOWN Limits

Do not make any limit adjustments until the
safety reversing sensors are completely
installed.

28

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

button. 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).

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 continuing on
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.

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 door does not open at least 5 feet:

Adjust the UP (open) force as explained in
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 or 5), try
lengthening the door arm. (see page 26).

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 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 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.

Adjustment Section: Pages 28 – 30

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.

WARNING

Adjustment Step 2

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.

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 two-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.

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.

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.

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.

29

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 updirection 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.

WARNING

Adjustment Step 4

Test the Safety Reverse System

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 26.

• 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 Sears Service Center
for garage door opener service.

GARAGE DOOR

One-inch Board

(or a 2x4 laid flat)

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.

30

Adjustment Step 3

Test The Safety Reversing Sensor

• 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.

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 control 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 button until down
travel is completed.

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.

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.

flat) object placed on the floor. If an adjustment
is made to either the force or the 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 emergency 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.

WARNING

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.

Having a Problem?

Situation Probable Cause and Solution

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

Opener operates
from the remote
control, but not from
the Door Control:

1. Is the Door Control 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 any door push button flashing? If your model has the Lock feature, make sure the
lock is 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:

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 29.

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 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

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 opener extends fully
downward.

3. Some installations may have shorter range due to a metal door, foil backed
insulation, or metal garage siding. (Antenna Extender Kit 41A3504)

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.

Having a Problem?

(continued)

Situation Probable Cause & Solution

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

1. Is something obstructing the door? Pull the red 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 29.

4. If door reverses in the

fully closed

position, decrease the travel limits (page 28).

Repeat 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:

The opener light:

. . . doesn't turn on:

Replace the light bulbs (75 watts maximum). Use a

standard neck

garage door opener

bulb if regular bulb burns out.

. . . doesn'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
emergency release 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 a professional garage door serviceman.

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 reinstalled, 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.

The opener won't
operate due to
power failure:

1. Use the emergency release to disconnect the trolley. The door can be opened and closed
manually. When the power is restored, press the Door Control push button and trolley will
automatically reconnect (unless trolley is in lockout position.) See page 32.

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 to disconnect the trolley. If the chain returns to normal height when
the trolley is disengaged and the door reverses on a one-inch board, no adjustments
are needed (see page 11).

35

The door opens but
won't close:

Check the safety reversing sensor. Remove any obstruction or align the receiving eye.
See page 23.

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.
