Mechanical

serious injury

Page 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, 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.

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.

Facing the door from inside the garage

The Protector System

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 opener light 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 garage door track 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.

Figure 2

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 the door track. 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 1.

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 both sensors. 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 4.

• Finger tighten the wing nuts.

Recommended Wire Routing

1. Using insulated staples, run the wires from both

sensors to the rail at the door header (see Figure 5).

2. Cross and twist the two wires where they meet the rail

(see inset A). Run the wires inside the channels at the top of the rail, along each side, to the power unit and pull taut (see inset B). Do not use the lower (trolley)

channels.

NOTE: If your access door is near the garage door, you may choose to install the door control at this time and run the door control wire along the rail with the sensor wires. Use one rail channel for the door control wire and the other channel for both sensor wires. If you choose this option, follow instructions 1-3 on page 21 now.

3. Thread the wires through the tabs on top of the drive

shaft cover.

4. With your screwdriver tip, tuck the wires snugly into

the rail channels. You will complete the wiring in Installation Step 7.

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.

To prevent dama ge to steel, alumin um, fiber glass or glass panel door s, do not rest the opener on the door without using a 2x4.

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.

Page 16

Installation Step 6

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" screws, lock washers and nuts.

• Check to make sure the 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.

The opener could fall and injure someone if it is not properly secured.

Installation Step 7

Install the Door Control and Connect all Wiring

DO NOT CONNECT TO LIVE ELECTRICAL WIRING. CONNECT ONLY TO 24 VOLT LOW VOLTAGE WIRES. CONNECTION TO LIVE WIRES OR HIGHER VOLTAGE MAY CAUSE SERIOUS INJURY FROM SHOCK, BURN OR ELECTROCUTION.

Children operating or playing with a garage door opener can injure themselves or others.

The garage door could close and cause serious injury or death. Do not allow children to operate the push button or the remote control transmitter.

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.

Locate the door control within sight of the door at a minimum height of 5 feet where small children cannot reach, and away from all moving parts of the door and door hardware.

The door control is typically attached directly to the wall. If installing into drywall, drill 5/32" holes and use the anchors provided. For pre-wired installations (as in new home construction), the multi-function door control can be mounted to a standard single gang box.

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. (Fig. 1)

2. Lighted door control: Fasten to wall with 6ABx1-1/2" selftapping screws.

Multi-function: Remove the white cover by gently pushing both thumbs against upper corners of cover on the back side of the door control (Fig. 2). Fasten with 6ABx1-1/4" selftapping screws (standard installation) or 6-32x1" machine screws (pre-wired installation) as follows: (Fig. 3)

• Install bottom screw, allowing 1/8" to protrude from the wall.

• Position bottom of door control over screw head and adjust

for snug fit.

• Install top screw with care to avoid cracking plastic

housing. Do not overtighten.

• Replace cover by inserting bottom tabs and snapping into

place. To remove cover after mounting, gently pry at top with paper clip or small flat head screwdriver.

NOTE: After installation, a green indicator light behind the cover will indicate proper connection. If not lit, the Lock and Light features will not function (reverse wires to correct).

3. Standard installation only: Run bell wire up wall and across ceiling to opener. Use insulated staples to secure 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 Control Center door on right panel of opener to access the terminal screws.

5. Thread all wires through the opening at the base of the drive

shaft cover (Fig. 4).

6. Insert the remaining wire through the hole in the power unit and strip 1/4" of insulation from each set of wires.

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.

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. 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 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.

• 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 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 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.)

Installation Step 12

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.

Page 23

All ONE-PIECE Doors

Assemble the Door Arm:

• Fasten the straight and curved door arm sections

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

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

• Secure with a ring fastener.

On one-piece doors, before connecting the door arm to the trolley the travel limits must be adjusted. Limit adjustment screws are located on the 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.

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 or button. Run the opener through a complete travel cycle.

• Does the door open and close completely?

• Does the door stay closed and not reverse unintentionally when fully closed?

If your door passes both of these tests, no limit adjustments are necessary unless the reversing test fails (see page 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.

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 monthly, and following all adjustments to force levels. 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.

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

Page 26

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.

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 or button until down travel is completed.

Without a properly working safety reversing sensor, persons (particularly children) could be seriously injured or killed if trapped by a closing garage door.

Repeat this

test once a month.

Your "Security Plus" opener will operate with:

• several Security Plus remote controls (with yellow

indicator lights) utilizing up to 8 functions. NOTE:

Open/Close/Stop operation counts as 1 function.

• one Keyless Entry System (with Security Plus logo) Follow the instructions below to program your opener to

match any additional remotes you may purchase. See Accessories on page 34.

To Add a Remote Control

1. Press and hold the selected remote control push button. See Figure 1.

2. Press and release the "Smart" (learn) button on the right side panel of the opener. See Figure 2. The indicator light on the panel will begin to blink and the opener lights will flash once.

3. Release the remote push button.

Now the opener will operate when the remote control push button is pressed. Test by pressing the remote button to see that the door goes up and down.

The garage door could

Do not allow children to operate the door control(s) or remote control transmitter(s).

A moving garage door could injure or kill someone under it.

Activate the opener only when you can see the door clearly, it is free of obstructions, and is properly adjusted.

Adding a remote can also be done from the door control, as follows:

1. With the door closed, press and hold a remote push button.

2. Press and hold the Light button on the door control.

3. Press and hold the door control push bar.

4. After the opener lights flash, release all buttons.

Test by pressing the remote push button.

To Erase All Remote Control Codes

Press and hold the "Smart" button on the opener panel until the indicator light turns off (about 6 seconds). All transmitter codes are now erased. Then follow the steps above to re-program each remote control.

To Control the Opener Lights

With Security Plus transmitters, a remote push button can be programmed to operate the opener lights without opening the door.

1. With the door closed, press and hold the remote button that you want to control the light.

2. Press and hold the Light button on the door control.

3. Press and hold the Lock button on the door control.

4. After the opener lights flash, release all buttons.

Test by pressing the remote push button. The opener lights should turn on or off but the door should not move.

Open/Close/Stop Operation

Your Security Plus remote control can be programmed to operate one door using all 3 buttons: the large button will only open the door, the middle button will only close the door, and the third button will stop the door’s movement. You may set up this feature as follows:

1. With the door closed, press and hold the large remote push button.

2. Press and hold the Lock button on the door control.

3. Press and hold the door control push bar.

When the opener lights flash, release all buttons. Test by pressing the large (Open) button on the remote. The door should open. Press it again while the door is open and nothing should happen. Press the middle (Close) button and the door should close. Press the third (Stop) button while the door is moving and it should stop immediately.

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.

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.

The door reverses for no apparent reason and opener lights blink for 5 seconds after reversing:

The opener lights… don't turn on:

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.

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

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.

Check the safety reversing sensor. Remove any obstruction or align the receiving eye. See page 18.

Replace the light bulb(s) (100 watts maximum). Use a standard neck garage door opener bulb if regular bulb burns out.

The opener strains or maximum force is needed to operate door:

The opener motor hums briefly, then won't work:

The opener won't operate due to power failure:

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.

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.

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 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.
