WARNING

WARNING

CAUTION

You'll Need Tools

During assembly, installation and adjustment of the opener, instructions will call for hand tools shown below.

3

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.

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.

Identify the type and height of your door and any
special conditions that exist and any additional
materials that may be required.

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.

Before you begin, survey your garage area to see whether any of the conditions below apply to your installation.
You may find it helpful to refer back to this page as you proceed with the installation of your opener.

Based on your particular requirements, there are
several installation steps which might call for
materials and/or hardware not included in the
carton.

• Step 1, page 12 - Look at the wall or ceiling above
the garage door. The header bracket

must

be

securely fastened to structural supports.

• Step 5, page 17 - Do you have a finished ceiling in
your garage? If so, a support bracket and
additional fastening hardware may be required.

• Safety reversing sensor, page 21 - Depending
upon garage construction, extension brackets (see
Accessories) or wood blocks may be needed to
fasten sensors to mounting locations.

• Step 10, page 22 - Floor mounting of the safety
reversing sensor will require hardware not
provided.

• Step 11, page 24 - Do you have a steel, aluminum,
fiberglass or glass panel door? If so, horizontal
and vertical reinforcement is required.

• Look at the garage door where it meets the floor.

It must close on the floor all the way across.
Otherwise, the safety reverse system may not
work properly. See page 30. Floor or door should

be repaired.

SECTIONAL Door Installation

• The opener can be installed within 4 feet of the left
or right of the door center if there is a torsion spring
or 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 12 and 24.

• Do you have an access door in addition to the
garage door? If not, Model 7702CB Outside Quick
Release is required. See page 38.

• If your door is more than 7 feet high, see rail
extension kit listed on page 38.

Follow instructions which apply to your door type
as illustrated.

To prevent damage to steel, aluminum,
fiberglass or glass panel doors, do not rest the
opener on the door without using a 2x4.

SECTIONAL Door & ONE-PIECE Door with Track

A 2x4 laid flat is convenient for setting an ideal
door-to-T-rail distance.

• Raise the opener onto a stepladder.

You will need help at this point if the ladder is
not tall enough.

• Open the door all the way and place a 2x4 laid flat
on the top section beneath the T-rail.

If the top panel hits the trolley when you raise
the door, pull down on the trolley release arm to
disconnect the inner and outer sections. The
trolley can remain disconnected until Step 12 is
completed.

ONE-PIECE Door without Track

• With the door fully open and parallel to the floor,
measure the distance from the floor to the top of
the door.

• Using a stepladder as a support, raise the opener
to the same distance as the door from the floor (it
will be at a slight angle as shown).

• The top of the door should be level with the top of
the opener. Do not position the opener more than
2" above this point.

Hang the Opener

Two representative installations are shown.
Yours may be different. Hanging brackets should

be angled, Figure 1, to provide rigid support. On
finished ceilings, Figure 2, attach a sturdy metal
bracket to structural supports before installing the
opener. The bracket and fastening hardware are not
supplied.

• Measure the distance from

each

side of the opener

to the structural support.

• Cut both pieces of the hanging bracket to required
lengths.

• Drill 3/16" pilot holes in the structural supports.

• Attach one end of each bracket to a support with
5/16"-18x1-7/8" lag screws.

• Fasten the opener to the hanging brackets with
5/16"-18x7/8" hex screws, lock washers and nuts.

• Check to make sure the T-rail is centered over the
door (or in line with the header bracket if the
bracket is not centered above the door).

• Remove the 2x4. Operate the door manually. If the
door hits the rail, raise the header bracket.

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.

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.

STANDARD WALL MOUNT

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.
Install a 6ABx1-1/4" self-tapping screw at this point,
allowing about 1/8" to protrude from the wall. Slip the
lower part of the door control over the screw head
and adjust for snug fit. Drill and install the top screw
with care to avoid cracking the plastic housing.

Do not

overtighten.

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.

•

For pre-wired installations,

partially install a 6-32x1"
machine screw into the bottom of the gang box,
allowing about 1/8" to protrude. Slip the lower part of
the door control over the screw head and adjust for
snug fit. Install top screw with care to avoid cracking
plastic housing.

Do not overtighten.

• Connect the bell wire to the opener terminal screws
as follows: white to 2 and white/red to 1.

• Replace the cover by inserting bottom tabs and
snapping into place. To remove the cover after
mounting, gently pry at the top with a paper clip or
small flat head screwdriver.

Installation Step 8

Attach the Manual 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 manual
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 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.

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

beginning on page 21.

• 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.

WARNING

To prevent electrocution, remove power from
the garage door opener

and

from the circuit

you plan to use for the permanent connection.

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
type outlet.

To avoid installation difficulties, do not run the
opener at this time.

Installation Step 9

Electrical Requirements

• To make a permanent connection through the

7/8" diameter 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.

To avoid installation difficulties, do not run the
opener at this time.

20

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,

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.

IMPORTANT INFORMATION ABOUT 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.

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.

INSTALLING THE BRACKETS
Be sure power to the opener is disconnected.

Install and align the brackets so the sensors will face
each other across the garage door, with the beam
from 4 – 6" above the floor.

They may be installed in one of three ways, as
follows.

Garage door track installation (preferred):

• Slip the curved arms over the rounded edge of each
door track, with the curved arms facing the door.
Snap into place against the side of the track. It
should lie flush, with the lip hugging the back edge
of the track, as shown in Figure 2.

If your door track will not support the bracket
securely, wall installation is recommended.

Wall installation:

• Place the bracket against the wall with curved arms
facing the door. Be sure there is enough clearance
for the sensor beam to be unobstructed.

• If additional depth is needed, an extension bracket
(see Accessories) or wood blocks can be used.

• Use bracket mounting holes as a template to locate
and drill (2) 3/16" diameter pilot holes on the wall at
each side of the door, from 4–6" above the floor.

• Attach brackets to wall with lag screws (not
provided).

• If using extension brackets or wood blocks, adjust
right and left assemblies to the same distance out
from the mounting surface. Make sure all door
hardware obstructions are cleared.

Floor installation:

• Use wood blocks or extension brackets (see
Accessories) to elevate sensor brackets so the
lenses will be 4-6" above the floor.

• Carefully measure and place right and left
assemblies at the same distance out from the wall.
Be sure all door hardware obstructions are cleared.

• Fasten to the floor with concrete anchors as shown.

MOUNTING AND WIRING THE SAFETY SENSORS

• Slide a 1/4"-20x1/2" carriage bolt head into the slot
on each sensor. Use wing nuts to fasten sensors to
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.

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.

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.

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 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.

• 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 Procedures for One-Piece Doors

Open Door Adjustment:

Decrease UP limit

• 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 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

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).

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.

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 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).

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 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.

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.

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 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.

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 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 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.

Adjustment Step 4

Test the Safety Reverse System

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.

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.

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 Protector System

®

• 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.

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 INSTRUCTIONS

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.

Having a Problem?

Situation Probable Cause & Solution

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

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:

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

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.

Having a Problem?

(continued)

Situation Probable Cause & Solution

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.

35

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 opener lights…

The door reverses for
no apparent reason
and opener light(s)
blink for 5 seconds
after reversing:

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.

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

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.

Setting a Temporary Password

In addition to your personal entry password which works at
all times, a 4-digit temporary password can be added for the
convenience of visitors or service persons.

This allows authorized persons a way to gain temporary
access. After a programmed number of hours or number of
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

temporary password:

1. Press the four buttons for your personal entry password
(not the last temporary password), then press and hold
the ✽ button.

The opener light will blink three times. Release the
button.

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

The opener light will blink four times.

3. To set the number of

hours

this temporary password will
work, press the number of hours (up to 255), then
press ✽.

OR

3. To set the number of

times

this temporary password will
work, press the number of times (up to 255), then press
#.

The opener light will blink once when the temporary
password has been learned.

Test by pressing the four buttons for the temporary
password, then press Enter. The door should move. If the
temporary password was set to a certain number of
openings, remember that the test has used up one opening.

To clear the temporary password, repeat steps 1-3, setting
the number of hours or times to 0 in step 3.
