Preparing your garage door

WARNING

Before you begin:

To prevent possible SERIOUS INJURY OR DEATH:

• Disable locks.

• ALWAYS call a trained door systems technician if

garage door binds, sticks, or is out of balance. An

unbalanced garage door may not reverse when

required.

• NEVER try to loosen, move or adjust garage door, door

springs, cables, pulleys, brackets or their hardware, all

of which are under EXTREME tension.

• Disable ALL locks and remove ALL ropes connected to

garage door BEFORE installing and operating garage

door opener to avoid entanglement.

• Remove any ropes connected to garage door.

• Complete the following test to make sure your

garage door is balanced and is not sticking or

binding:

1. Lift the door about halfway as shown. Release

the door. If balanced, it should stay in place,

supported entirely by its springs.

2. Raise and lower the door to see if there is any

binding or sticking.

If your door binds, sticks, or is out of balance, call a

trained door systems technician.

CAUTION

To prevent damage to garage door and opener:

• ALWAYS disable locks BEFORE installing and operating

the opener.

• ONLY operate garage door opener at 120V, 60 Hz to

avoid malfunction and damage.

• Do you have an access door in addition to the

garage door? If not, Model 1702LM Outside Quick

Release is required. See Accessories page.

Planning

Identify the type and height of your garage door.

Survey your garage area to see if any of the

conditions below apply to your installation. Additional

materials may be required. You may find it helpful to

refer back to this page and the accompanying

illustrations as you proceed with the installation of

your opener.

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

Any gap between the floor and the bottom of the

door must not exceed 1/4" (6 mm). Otherwise, the

safety reversal system may not work properly. See

Adjustment Step 3. Floor or door should be

repaired.

Depending on your requirements, there are several

installation steps which may call for materials or

hardware not included in the carton.

SECTIONAL DOOR INSTALLATIONS

• Installation Step 1 – Look at the wall or ceiling

above the garage door. The header bracket must

be securely fastened to structural supports.

• Do you have a steel, aluminum, fiberglass or glass

panel door? If so, horizontal and vertical reinforce-

ment is required (Installation Step 11).

• Installation Step 5 – Do you have a finished ceiling

in your garage? If so, a support bracket and

additional fastening hardware may be required.

• The opener should be installed above the center of

the door. If there is a torsion spring or center

bearing plate in the way of the header bracket, it

may be installed within 4 feet (1.22 m) to the left or

right of the door center. See Installation Steps 1

and 11.

• Installation Step 10 – Depending upon garage

construction, extension brackets or wood blocks

may be needed to install sensors.

• Installation Step 10 – Alternate floor mounting of

the safety reversing sensor will require hardware

not provided.

• If your door is more than 7 feet (2.13 m) high, see

rail extension kits listed on Accessories page.

Electrical Requirements

To prevent possible SERIOUS INJURY or DEATH from

electrocution or fire:

To avoid installation difficulties, do not run the

opener at this time.

• Be sure power is not connected to the opener, and

disconnect power to circuit BEFORE removing cover to

establish permanent wiring connection.

• Garage door installation and wiring MUST be in

compliance with all local electrical and building codes.

• NEVER use an extension cord, 2-wire adapter, or

change plug in ANY way to make it fit outlet. Be sure

the opener is grounded.

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.

INSTALLATION STEP 10

WARNING

Install The Protector System

Be sure power is not connected to the garage door

opener BEFORE installing 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.

To prevent SERIOUS INJURY or DEATH from a closing

garage door:

• Correctly connect and align the safety reversing sensor.

This required safety device MUST NOT be disabled.

• Install the safety reversing sensor so beam is NO

HIGHER than 6" (15 cm) above garage floor.

IMPORTANT INFORMATION ABOUT

THE SAFETY REVERSING SENSOR

When properly connected and aligned, the sensor

will detect an obstacle in the path of its electronic

beam. The sending eye (with an amber 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 opener lights will flash 10 times.

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 units must be installed inside the garage so that

the sending and receiving eyes face each other

across the door, no more than 6" (15 cm) 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 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.

The mounting brackets are designed to clip onto the

track of sectional garage doors without additional

hardware.

TROUBLESHOOTING THE SAFETY

REVERSING SENSORS

• Strip 1/4" (6 mm) 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 (Figure 6).

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 terminal connections.

ALIGNING THE SAFETY REVERSING 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.

• 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:

The sending eye amber 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.

• Check alignment.

• Check for an open wire to the receiving eye.

3. If the receiving eye indicator light is dim, realign

either sensor.

• Loosen the sending eye wing nut and readjust,

aiming directly at the receiving eye. Lock in place.

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 blink 10 times. (If bulbs are not

installed, 10 clicks can be heard.) See page 21.

• 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.

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.

- 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" (5 cm) of trolley travel.

• Open door adjustment: decrease UP

travel limit

- Turn the UP limit adjustment screw counter-

clockwise 5-1/2 turns.

3. 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.

- Press the Door Control push 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" (5 cm) of trolley travel.

• 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.

NOTE: When setting the up limit on the following

page, the door should not have a "backward" slant

when fully open as illustrated below. A slight

backward slant will cause unnecessary bucking

and/or jerking operation as the door is being opened

or closed from the fully open position.

ADJUSTMENT STEP 1

WARNING

Without a properly installed safety reversal system,

persons (particularly small children) could be

SERIOUSLY INJURED or KILLED by a closing garage

door.

• Incorrect adjustment of garage door travel limits will

interfere with proper operation of safety reversal

system.

Adjust the UP and DOWN Travel

Limits

Limit adjustment settings regulate the points at which

the door will stop when moving up or down.

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?

• If one control (force or travel limits) is adjusted, the

other control may also need adjustment.

• After ANY adjustments are made, the safety reversal

system MUST be tested. Door MUST reverse on

contact with 1-1/2" (3.8 cm) high object (or 2x4 laid

flat) on floor.

• 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 (Adjustment Step 3, page 30).

Adjustment procedures are outlined below. Read the

procedures carefully before proceeding to

Adjustment Step 2. Use a screwdriver to make limit

adjustments. Run the opener through a complete

travel cycle after each adjustment.

CAUTION

To prevent damage to vehicles, be sure fully open door

provides adequate clearance.

NOTE: Repeated operation of the opener during

adjustment procedures may cause the motor to

overheat and shut off. Simply wait 15 minutes and

try again.

Adjustment Step 2.

• If the door reverses when closing and there is

no visible interference to travel cycle:

• If the door does not close completely:

Increase down travel. Turn the down limit

adjustment screw counterclockwise. One turn

equals 2" (5 cm) of travel.

If the opener lights are flashing, the Safety

Reversing Sensors are either not installed,

misaligned, or obstructed. See Troubleshooting,

page 23.

If door still won't close completely and the trolley

bumps into the pulley bracket (page 4), try

lengthening the door arm (page 26) and

decreasing the down limit.

Test the door for binding: Pull the emergency

release handle. Manually open and close the door.

If the door is binding or unbalanced, call for a

trained door systems technician. If the door is

balanced and not binding, adjust the DOWN

(close) force. See Adjustment Step 2.

• If the opener reverses in fully closed position:

Decrease down travel. Turn the down limit

adjustment screw clockwise. One turn equals 2"

(5 cm) of travel.

ADJUSTMENT STEP 2

WARNING

Adjust the Force

Without a properly installed safety reversal system,

persons (particularly small children) could be

SERIOUSLY INJURED or KILLED by a closing garage

door.

Force adjustment controls are located on the back

panel of the motor unit. Force adjustment settings

regulate the amount of power required to open and

close the door.

• Too much force on garage door will interfere with

proper operation of safety reversal system.

• NEVER increase force beyond minimum amount

required to close garage door.

• NEVER use force adjustments to compensate for a

binding or sticking garage door.

• If one control (force or travel limits) is adjusted, the

other control may also need adjustment.

• After ANY adjustments are made, the safety reversal

system MUST be tested. Door MUST reverse on

contact with 1-1/2" (3.8 cm) high object (or 2x4 laid

flat) on floor.

If the forces are set too light, door travel may be

interrupted by nuisance reversals in the down

direction and stops in the up direction. Weather

conditions can affect the door movement, so

occasional adjustment may be needed.

The maximum force adjustment range is about

3/4 of a complete turn. Do not force controls

beyond that point. Turn force adjustment controls

with a screwdriver.

NOTE: If anything interferes with the door’s upward

travel, it will stop. If anything interferes with the

door’s downward travel (including binding or

unbalanced doors), it will reverse.

HOW AND WHEN TO ADJUST THE FORCES

1. Test the DOWN (close) force

Force Adjustment Controls

• 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 1-1/2"

(3.8 cm) obstruction. See Adjustment Step 3,

page 30.

If the door is hard to hold or doesn't reverse,

DECREASE the DOWN (close) force by turning

the control counterclockwise. Make small

adjustments until the door reverses normally. After

each adjustment, run the opener through a

complete cycle.

• If the door reverses during the down (close)

cycle and the opener lights aren't flashing,

INCREASE DOWN (close) force by turning the

control clockwise. Make small adjustments until the

door completes a close cycle. After each

BACK PANEL

adjustment, run the opener through a complete

travel cycle. Do not increase the force beyond the

minimum amount required to close the door.

2. Test the UP (open) force

• Grasp the door bottom when the door is about

halfway through UP (open) travel. The door should

stop. If the door is hard to hold or doesn't stop,

DECREASE UP (open) force by turning the control

counterclockwise. Make small adjustments until the

door stops easily and opens fully. After each

adjustment, run the opener through a complete

travel cycle.

FORCE ADJUSTMENT LABEL

• If the door doesn’t open at least 5 feet (1.5 m),

INCREASE UP (open) force by turning the control

clockwise. Make small adjustments until door

opens completely. Readjust the UP limit if

necessary. After each adjustment, run the opener

ADJUSTMENT STEP 3

WARNING

Test the Safety Reversal System

Without a properly installed safety reversal system,

persons (particularly small children) could be

SERIOUSLY INJURED or KILLED by a closing garage

door.

TEST

• With the door fully open, place a 1-1/2" (3.8 cm)

board (or a 2x4 laid flat) on the floor, centered

under the garage door.

• Safety reversal system MUST be tested every month.

• If one control (force or travel limits) is adjusted, the

other control may also need adjustment.

• After ANY adjustments are made, the safety reversal

system MUST be tested. Door MUST reverse on

contact with 1-1/2" (3.8 cm) high object (or 2x4 laid

flat) on the floor.

• Operate the door in the down direction. The door

must reverse on striking the obstruction.

ADJUST

• 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.

NOTE: 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.

• Repeat the test.

• When the door reverses on the 1-1/2" (3.8 cm)

board, remove the obstruction and run the opener

through 3 or 4 complete travel cycles to test

adjustment.

IMPORTANT SAFETY CHECK:

Repeat Adjustment Steps 1, 2 and 3 after:

• Each adjustment of door arm length, limits, or

force controls.

• Any repair to or adjustment of the garage door

(including springs and hardware).

1-1/2" (3.8 cm) board

(or a 2x4 laid flat)

• Any repair to or buckling of the garage floor.

• Any repair to or adjustment of the opener.

WARNING

Without a properly installed safety reversing sensor,

persons (particularly small children) could be

SERIOUSLY INJURED or KILLED by a closing garage

door.

ADJUSTMENT STEP 4

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.

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).

If the opener closes the door when the safety

reversing sensor is obstructed (and the sensors

are no more than 6" (15 cm) above the floor), call

for a trained door systems technician.

Using Your Garage Door Opener

Your Security✚^®opener and hand-held remote

control have been factory-set to a matching code

which changes with each use, randomly accessing

over 100 billion new codes. Your opener will operate

with up to eight Security✚^®remote controls and one

Security✚^®Keyless Entry System. If you purchase a

new remote, or if you wish to deactivate any remote,

follow the instructions in the Programming section.

5. If obstructed while closing, the door will reverse. If

the obstruction interrupts the sensor beam, the

opener lights will blink for five seconds.

6. If obstructed while opening, the door will stop.

7. 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 misaligned, the

door won't close from a hand-held remote. However,

you can close the door with the Door Control, the

Outside Keylock, or Keyless Entry, if you activate

them until down travel is complete. If you release

them too soon, the door will reverse.

Activate your opener with any of the following:

• The hand-held Remote Control: Hold the push

button down until the door starts to move.

• The wall-mounted Door Control: Hold the push

button or bar down until the door starts to move.

• The Keyless Entry (See Accessories): If supplied

with your garage door opener, it must be

The opener light will turn on under the following

Care of Your Opener

1. The opener doesn't operate from either the

Door Control or the remote control:

LIMIT AND FORCE ADJUSTMENTS:

Weather conditions may cause

some minor changes in door

operation requiring some

• 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.)

• Have you disabled all door locks? Review

installation instruction warnings on page 11.

• Is there a build-up of ice or snow under the door?

The door may be frozen to the ground. Remove

any restriction.

• The garage door spring may be broken. Have it

replaced.

2. Opener operates from the remote, but not from

the Door Control:

• Manually operate door. If it is unbalanced or

binding, call a trained door systems technician.

• Is the door control lit? If not, remove the bell wire

from the motor unit terminals. 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.

• Check to be sure door opens & closes fully. Adjust

limits and/or force if necessary. (See pages 28

and 29.)

• Repeat the safety reverse test. Make any

necessary adjustments. (See page 30.)

Twice a Year

• Check chain tension. Disconnect trolley first. Adjust

if necessary (see page 11).

• Are the wiring connections correct? Review

Installation Step 6, page 18.

Once a Year

3. The door operates from the Door Control, but

not from the remote control:

• Oil door rollers, bearings and hinges. The opener

does not require additional lubrication. Do not

grease the door tracks.

• Is the door push bar flashing? If your model has

the Lock feature, make sure it is off.

THE REMOTE CONTROL BATTERY

• Program the opener to match the remote control

code. (Refer to instructions on the motor unit

panel.) Repeat with all remotes.

WARNING

To prevent possible SERIOUS INJURY or DEATH:

• NEVER allow small children near batteries.

• If battery is swallowed, immediately notify doctor.

4. The remote control has short range:

• Change the location of the remote control in your

car.

• Check to be sure the antenna on the side or back

panel of motor unit extends fully downward.

• Some installations may have shorter range due to

a metal door, foil backed insulation, or metal

garage siding.

The lithium battery should

produce power for up to

5 years. To replace battery, use

the visor clip or screwdriver

blade to pry open the case as

shown. Insert battery positive

side up.

5. 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 89LM can be installed. This

kit was designed to minimize vibration to the house

and is easy to install.

Dispose of old battery properly.

NOTICE: To comply with FCC and or Industry Canada (IC) rules, adjustment or

11. The door reverses for no apparent reason and

opener lights blink for 5 seconds after

reversing:

Having a Problem? (Continued)

6. The garage door opens and closes by itself:

• Be sure that all remote control push buttons are

off.

• Check the safety reversing sensor. Remove any

obstruction or align the receiving eye. See

Installation Step 10.

• Remove the bell wire from the door control

terminals and operate from the remote 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 motor unit.

12. The opener lights don't turn on:

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

A19 standard neck garage door opener bulb if

regular bulb burns out.

• Clear memory and re-program all remote controls.

13. The opener lights don't turn off:

7. The door doesn't open completely:

• Is the Light feature on? Turn it off.

• Is something obstructing the door? Is it out of

balance, or are the springs broken? Remove the

obstruction or repair the door.

14. The opener strains or maximum force is

needed to operate door:

• The door may be out of balance or the springs

may be 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 a

trained door systems technician. Do not increase

the force to operate the opener.

• If the door is in good working order but now

doesn't open all the way, increase the up force.

See Adjustment Step 2.

• If the door opens at least 5 feet (1.5 m), the travel

limits may need to be increased. One turn equals

2" (5 cm) of travel. See Adjustment Step 1.

Repeat the safety reverse test after the adjustment is

complete.

8. The door stops but doesn't close completely:

15. The opener motor hums briefly, then won't

work:

• Review the travel limits adjustment procedures on

page 28.

• The garage door springs may be broken. See

above.

Repeat the safety reverse test after any adjustment

of door arm length, close force or down limit.

• If the problem occurs on the first operation of the

opener, door may be locked. Disable the door lock.

9. The door opens but won't close:

Repeat the safety reverse test after the adjustment is

complete.

• If the opener lights blink, check the safety

reversing sensor. See Installation Step 10.

16. The opener won't operate due to power

failure:

• If the opener lights don’t blink and it is a new

installation, check the down force. See Adjustment

Step 2, page 29. For an existing installation, see

below.

• Use the emergency release handle to disconnect

the trolley. The door can be opened and closed

manually. When power is restored, press the Door

Control push bar and trolley will automatically

reconnect (unless trolley is in lockout position.)

See page 32.

Repeat the safety reverse test after the adjustment

is complete.

10. The door reverses for no apparent reason and

opener lights don’t blink:

• 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.

• Is something obstructing the door? Pull the

emergency release handle. Operate the door

manually. If it is unbalanced or binding, call a

trained door systems technician.

17. The chain droops or sags:

• Clear any ice or snow from the garage floor area

where the door closes.

• 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 2x4 laid

flat, no adjustments are needed. (See page 11.)

• Review Adjustment Step 2 on page 29.

• If door reverses in the fully closed position,

decrease the travel limits (Adjustment Step 1).

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.
