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, any special conditions that exist, and any additional materials that may be required.
Test Your Door for Balance
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.

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.
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.
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.
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.
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.

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 or
ONE-PIECE Door with Track
A 2x4 laid flat is convenient for setting an ideal door­to-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 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 3" above this point.

Installation Step 7
Install the Door Control and Connect all Wiring
17
Children operating or playing with a garage door opener can injure themselves or others.
The garage door could
close and cause serious injury or death.
Install the door control (or any additional push buttons) out of the reach of children and away from all moving parts of the door and door hardware,
but where the garage door is visible.
Do not allow children to operate the push button(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.
Install Door Control
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.
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 by color: white to 2 and white/red to 1 (see Figure 1).
2. Fasten the Multi-Function Door Control uses 6ABx1-1/4" screws. If installing into drywall, drill 5/32" holes and use the anchors provided.
3. 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. If your access door is near the
garage door, you may run this wire with the Safety Reversing Sensor wires along the top of the rail. See page 14.
4. Remove the Control Center door on the right panel of the opener to access the terminal screws.
Connect Door Control and Sensor Wiring
5. Thread all wires through the opening at the base of the drive shaft cover (see Figure 2).
6. Insert the remaining wire through the hole in the power unit and strip 1/4" of insulation from each set of wires.
7. Connect the door control wire to the opener terminal screws: white to 2 and white/red to 1. (See Figure 3.)
8. Separate the sensor white and white/black wires sufficiently to connect to the opener terminal screws: white to 2 and white/black to 3.
9. 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.

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.
If permanent wiring is required by your local code, refer to the following procedure:
Installation Step 8

Electrical Requirements

To make a permanent connection through the 7/8" diam. 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.
18
To prevent electrocution or fire,
installation and wiring must be in compliance with local electrical and building codes.
Do NOT use an extension cord, 2-wire adapter, or change the plug in any way to make it fit your outlet.
To avoid installation difficulties,
do not run the opener until Step 9 below.
To prevent electrocution,
remove power from the
garage door opener
and
from the circuit you plan to
use for the permanent connection.
Installation Step 9
Complete Safety Reversing Sensor Installation
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.
Trouble Shooting
1. If the sending eye indicator light does not glow steadily after installation, check for:
• Electric power to the opener.
• A short in the white or white/black wires. These can occur under staples or at screw terminal connections.
• Incorrect wiring between sensors and opener.
• An open wire (wire break).
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 12.

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.
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.

• Install a 100 watt maximum light bulb in each socket. The lights will turn ON and remain lit for approximately 4-1/2 minutes when power is connected. Then the lights will turn OFF.
• Insert bottom lens tabs into slots on chassis and tilt towards chassis to engage top tabs, then drop down gently into place. (See illustration.)
• To remove, lift lens up and gently tilt slightly outward and down, then pull out to clear bulbs. Use care to
avoid snapping off bottom lens tabs.
• If the bulbs burn out prematurely, replace with standard neck Garage Door Opener bulbs. (Fluorescent bulbs are
not recommended because of possible interference with receiver/transmitter signals.)

Fasten Door Bracket

Follow instructions which apply to your door type as illustrated below or on page 21.
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.

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 right side panel as shown on page 24. Follow adjustment procedures below.
Adjustment Procedures for One-Piece Doors
Open Door Adjustment:
Decrease UP Travel Limit
• Turn the UP limit adjustment screw counter-clockwise
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 Travel 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.

Adjustment Step 1
Adjust the UP and DOWN Limits
Do not make any limit adjustments until the safety reversing sensors are completely installed.
24
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 26).
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.
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, try lengthening the door arm. (Page 22.)
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 8/9.
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 18.
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 24 – 26
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 monthly, and following all adjustments to the travel limits. See page 26.

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 26. 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.
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. 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 small adjustments until door opens completely. Readjust 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 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.
25
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 up direction if anything interferes with its travel. The door will reverse in the down direction if anything interferes with its travel (including binding or unbalanced doors).
If the forces are set too light, door travel may be interrupted by nuisance reversals in the down direction and stops in the up direction. Weather conditions can affect the door movement, so occasional adjustment may be needed.
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.
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 22.
• 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 for professional garage door service.
Important Safety Check
Repeat Adjustment Steps 1-4 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.
26
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 light will flash for 5 seconds.
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 26. 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 one of the controls (either force or limits of travel), the other control may need to be adjusted also, 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.

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 7.
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 & 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 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 Installation Step 7, page 17.
The door operates from the door control, but not from the remote control:
1. Is the door push bar flashing? If your model has the Lock feature, 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. If the door has been working properly but now doesn't open all the way, increase the up force. See page 25.
2. Is something obstructing the door? Remove the obstruction or repair the door.
3. If door opens at least 5 feet, the travel limits may need to be increased. One turn equals 2 inches of travel. See page 24.
Repeat the safety reverse test after the adjustment is complete.
The door stops but doesn't close completely:
Review the travel limits adjustment procedures on page 24.
Repeat the safety reverse test after any adjustment of door arm length, close force or down limit.
30
1. Change the location of the remote control in your car.
2. Check to be sure the antenna on the right side panel of opener extends fully.
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 door reverses for no apparent reason and opener lights don't blink:
The door reverses for no apparent reason and opener lights blink for 5 seconds after reversing:
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 25.
4. If door reverses in the fully closed position, decrease the travel limits (page 24).
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… don't turn on:
Replace the light bulb(s) (100 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.
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 manual release handle to disconnect the trolley. Open and close the door manually. A properly balanced door will stay in any point of travel while being supported entirely by its springs. If it does not, disconnect the opener and call for professional garage door service. Do not
increase the force to operate the opener.
The opener motor hums briefly, then won't work:
1. The garage door springs are broken. See above.
2. If the problem occurs on the first operation of the opener, door may be locked. Disable the
door lock.
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 power is restored, press the Door Control push bar or button and trolley will automatically reconnect (unless trolley is in lockout position.) See page 28.
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.
31
The door opens but won't close:
1. If the opener lights blink, check the safety reversing sensor. See page 18.
2. If the opener lights do not blink and it is a new installation, check the down force. See Adjustment Step 2, page 25. For an existing installation, see below.
Repeat the safety reverse test after the adjustment is complete.
Check the safety reversing sensor. Remove any obstruction or align the receiving eye. See page 18.
