Preparing your garage door
WARNING
Before you begin:
• Disable locks.
• 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.
To prevent possible SERIOUS INJURY OR DEATH:
• 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.
CAUTION
WARNING
CAUTION
To prevent damage to garage door and opener:
• ALWAYS disable locks BEFORE installing and operating

Planning
• Do you have an access door in addition to the
garage door? If not, Model 1702LM Outside Quick
Release is required. See Accessories page.
• 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.
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.
Depending on your requirements, there are several
installation steps which may call for materials or
hardware not included in the carton.
• Installation Step 1 – Look at the wall or ceiling
above the garage door. The header bracket must
be securely fastened to structural supports.
• Installation Step 5 – Do you have a finished ceiling
in your garage? If so, a support bracket and
additional fastening hardware may be required.
• 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.
SECTIONAL DOOR INSTALLATIONS
• Do you have a steel, aluminum, fiberglass or glass
panel door? If so, horizontal and vertical reinforcement is required (Installation Step 11).
• 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.
• If your door is more than 7 feet (2.13 m) high, see
rail extension kits listed on Accessories page.
SECTIONAL DOOR INSTALLATION
Horizontal and vertical reinforcement
is needed for lightweight garage doors
(fiberglass, steel, aluminum, door with
glass panels, etc.). See page 24 for details.

®
Be sure power is not connected to the garage door
opener BEFORE installing the safety reversing sensor.
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.
CAUTION
The safety reversing sensor must be connected
and aligned correctly before the garage door
opener will move in the down direction.
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.
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 mounting brackets are designed to clip onto the
track of sectional garage doors without additional
hardware.
Safety Reversing Sensor
6" (15 cm) max. above floor
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.

TROUBLESHOOTING THE SAFETY
REVERSING 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 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 opener lights will blink 10 times. (If bulbs are not
installed, 10 clicks can be heard.) See page 21.
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.
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.
• 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.

INSTALLATION STEP 11
Fasten the Door Bracket
To prevent damage to garage door, reinforce inside of
door with angle iron both vertically and horizontally.
Follow instructions which apply to your door type
as illustrated below or on the following page.
A horizontal reinforcement brace should be long
enough to be secured to two or three vertical
supports. A vertical reinforcement brace should
cover the height of the top panel.
Figure 1 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.
NOTE: Many door reinforcement kits provide for
direct attachment of the clevis pin and door arm. In
this case you will not need the door bracket; proceed
to Step 12.

WARNING
ADJUSTMENT STEP 1
Adjust the UP and DOWN Travel
Limits
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.
• 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.
CAUTION
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?
• 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.
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.
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.

• 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.
CAUTION
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.
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
• 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
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.
• 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
through a complete travel cycle.

ADJUSTMENT STEP 3
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.
• 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.
CAUTION
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.
• 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).
• Any repair to or buckling of the garage floor.
• Any repair to or adjustment of the opener.

Vibration Isolator Kit 89LM can be installed. This
kit was designed to minimize vibration to the house
and is easy to install.
Having a Problem? (Continued)
11. The door reverses for no apparent reason and
opener lights blink for 5 seconds after
reversing:
• Check the safety reversing sensor. Remove any
obstruction or align the receiving eye. See
Installation Step 10.
6. The garage door opens and closes by itself:
• Be sure that all remote control push buttons are
off.
• 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.
• Clear memory and re-program all remote controls.
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.
13. The opener lights don't turn off:
• Is the Light feature on? Turn it off.
7. The door doesn't open completely:
• Is something obstructing the door? Is it out of
balance, or are the springs broken? Remove the
obstruction or repair the door.
• 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:
• 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.
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.
15. The opener motor hums briefly, then won't
work:
• The garage door springs may be broken. See
above.
• If the problem occurs on the first operation of the
opener, door may be locked. Disable the door lock.
Repeat the safety reverse test after the adjustment is
complete.
9. The door opens but won't close:
• If the opener lights blink, check the safety
reversing sensor. See Installation Step 10.
• 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.
Repeat the safety reverse test after the adjustment
is complete.
16. The opener won't operate due to power
failure:
• 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.
• 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.
10. The door reverses for no apparent reason and
opener lights don’t blink:
• 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.
• Clear any ice or snow from the garage floor area
where the door closes.
• 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.
17. The chain droops or sags:
• It is normal for the chain to droop slightly in the
closed door position. Use the emergency release
rope and handle to disconnect the trolley. If the
chain returns to the normal height when the trolley
is disengaged, and the door reverses on a 2x4 laid
flat, no adjustments are needed. (See page 11.)
