Without a properly working safety reversing sensor, persons (particularly children) could be injured or killed by a closing garage door.
Read and follow all
instructions. To protect small children, install the safety reversing
sensor so that the beam will be no higher than 4"-6" above the garage floor.
Disconnect power to the garage door opener before installing the safety reversing sensor.

®
IMPORTANT INFORMATION ABOUT THE SAFETY REVERSING SENSOR
The safety reversing sensor must be connected and aligned correctly before the garage door opener will move in the down direction. This is a required safety device and cannot be disabled.
When properly connected and aligned, the safety reversing sensor will detect an obstacle in the path of its electronic beam. The sending eye (with an orange indicator light) transmits an invisible light beam to the receiving eye (with a green indicator light). If an obstruction breaks the light beam while the door is closing, the door will stop and reverse to full open position, and the opener light 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, 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.

INSTALLING THE BRACKETS Be sure power to the opener is disconnected.
Install and align the brackets so the sensors will face each other across the garage door, with the beam from 4 – 6" above the floor.
They may be installed in one of three ways, as follows.
Garage door track installation (preferred):
• Slip the curved arms over the rounded edge of each door track, with the curved arms facing the door. Snap into place against the side of the track. It should lie flush, with the lip hugging the back edge of the track, as shown in Figure 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. (See Warning on page 16.)
• Attach brackets to wall with lag screws (not provided).
• If using extension brackets or wood blocks, adjust right and left assemblies to the same distance out from the mounting surface. Make sure all door hardware obstructions are cleared.
Floor installation:
• Use wood blocks or extension brackets (see Accessories) to elevate sensor brackets so the lenses will be 4-6" above the floor.
• Carefully measure and place right and left assemblies at the same distance out from the wall. Be sure all door hardware obstructions are cleared.
• Fasten to the floor with concrete anchors as shown.

Mounting and Wiring the Safety Sensors
• Slide a 1/4"-20x1/2" carriage bolt head into the slot on each sensor. Use wing nuts to fasten sensors to brackets, with lenses pointing toward each other across the door. Be sure the lens is not obstructed by a bracket extension. See Figure 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.

Position the Opener

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 13 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.

Children operating or playing with a garage door opener can injure themselves or other s.
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 a way from all mo ving 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 onl y when the door is pr operly adjusted, you can see it c learl y, 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.
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 Lighted Door Control Button securely with 6ABx1-1/2" 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 18.
4. Remove the Control Center door on the right panel of the opener to access the terminal screws.
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.

Page 22
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.
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.
22
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

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 16.

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.)

Fasten Door Bracket

Follow instructions which apply to your door type as illustrated below or on page 25.
To prevent damage to steel, aluminum, fiberglass or glass panel doors, always reinforce the inside of the door both vertically and horizontally with an angle iron.
A horizontal brace should be long enough to be secured to 2 vertical supports. A vertical brace should cover the height of the top panel.
The illustration shows one piece of angle iron as the horizontal brace. For the vertical brace, 2 pieces of angle iron are used to create a U-shaped support. The best solution is to check with your garage door manufacturer for an opener installation door reinforcement kit.
• Center the door bracket on the previously marked
vertical guideline used for the header bracket installation. Note 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 28. 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 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 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.

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 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 30).
Adjustment procedures are outlined below. Run the
opener through a complete travel cycle after each adjustment.
Repeated operation of the opener during adjustment procedures may cause the motor to overheat and shut off. Simply wait 15 minutes and try again.
Read the procedures carefully before proceeding to Adjustment Step 2. Use a screwdriver to make limit adjustments.
stop when moving up or down.
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 30.
How and When to Adjust the Limits
If the door does not 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 26.)
If you have adjusted the door arm to the maximum length and the door still will not close completely, lower the header bracket. See Installation Step 1, pages 12 and 13.

If the opener reverses in fully closed position:
Decrease down travel. Turn the DOWN limit adjustment screw clockwise. One turn equals 2" of travel.
If the door reverses when closing and there is no visible interference to travel cycle:
If the opener lights are flashing, the Safety Reversing Sensors are either not installed, misaligned, or obstructed. See Troubleshooting, page 22.
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.

Page 29
Adjustment Step 2
Adjust the Force
Too much force on the door will interfere with the proper operation of the safety reverse system.
The door might not reverse properly when required and could seriously injure or kill someone under it.
Do not increase the force beyond the minimum amount required to close the door. Do not use the force adjustments to compensate for a binding or sticking garage door. Test the safety reverse system monthly, and following all adjustments to force levels. See page 30.

How and When to Adjust the Forces
Test the DOWN (close) force
Grasp the door bottom when the door is about halfway through DOWN (close) travel. The door should reverse.
Reversal halfway through down travel does not guarantee reversal on a one-inch obstruction. See page 30. If the door is hard to hold or doesn't reverse,
decrease the DOWN (close) force by turning the control counterclockwise.
Make 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.
29
Force adjustment controls are located on the right panel of the opener. Force adjustment settings regulate the amount of power required to open and close the door.
The door will stop in the 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 30
Adjustment Step 4

Test the Safety Reverse System

Test
• With the door fully open, place a one-inch board (or a 2x4 laid flat) on the floor, centered under the garage door.
• Operate the door in the down direction. The door must
reverse on striking the obstruction.
Adjustment
If the door stops on the obstruction, it is not traveling far enough in the down direction.
• Increase the DOWN limit by turning the DOWN limit adjustment screw counterclockwise 1/4 turn.
• Repeat the test.
On a sectional door, make sure limit adjustments do not force the door arm beyond a straight up and down position. See the illustration on page 26.
• When the door reverses on the one-inch board, 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.
30
Adjustment Step 3

Test The Protector System

®
• Press the remote control push button to open the door.
• Place the opener carton in the path of the door.
• Press the remote control push button to close the door.
The door will not move more than an inch, and the opener 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 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

IMPORTANT SAFETY INSTRUCTIONS

To reduce the risk of severe injury or death to persons:
1. READ AND FOLLOW ALL INSTRUCTIONS.
2. Do not permit children either to operate or to play with the opener. Keep remote control in a location inaccessible to children.
3. Operate opener only when the door is in full view and free from any obstruction. Keep the door in sight until it is completely closed. NO ONE SHOULD CROSS THE PATH OF THE MOVING DOOR.
4. Check safety reversal system monthly. See page 30. The garage door MUST reverse on contact with a one inch object (or a 2x4 board laid flat) placed on the floor. If an adjustment is made to 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.

Activate the opener with any of the following:
• The Remote Control Transmitter. Hold push button
down until the door starts to move.
• The Door Control. Hold push button down until the
door starts to move.
• The Outside Keylock or Keyless Entry. (See
Accessories)
When the opener is activated with the safety reversing sensor installed and correctly aligned:
1. If open, the door will close. If closed, it will open.
2. If closing, the door will reverse.
3. If opening, the door will stop (allowing space for entry and exit of pets and for fresh air).
4. If the door has been stopped in a partially open position, it will close.
5. If obstructed while closing, the door will reverse.
6. If obstructed while opening, the door will stop.
7. The garage door will reverse in the closing cycle, and the opener lights will blink for 5 seconds, when the invisible beam is broken. 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 not aligned correctly, the door won't close from any remote transmitter. You can close the door with the Door Control, the Outside Keylock, or Keyless Entry, however, if you activate them until down travel is complete. If you release them too soon, the door will reverse.
Opener Lights will turn on under the following conditions: When the opener is initially plugged in; when the power is interrupted; when the opener is activated. They will turn off automatically after 4-1/2 minutes or provide constant light when the Light feature is activated.
Lights will also turn on when someone walks through the open garage door. Bulb size is 100 watts maximum.
Lockout position
(Manual disconnect)
To reconnect
Weak or broken springs could allow an open door to fall (either rapidly or unexpectedly), resulting in serious injury, death or property damage .

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 11.
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 21.
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 29.
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 28.
Repeat the safety reverse test after the adjustment is complete.
The door stops but doesn't close completely:
Review the travel limits adjustment procedures on page 28.
Repeat the safety reverse test after any adjustment of door arm length, close force or down limit.
34
1. Change the location of the remote control in your car.
2. Check to be sure the antenna on the 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.
Page 35
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 29.
4. If door reverses in the fully closed position, decrease the travel limits (page 28).
Repeat the safety reverse test after adjustments to force or travel limits. The need for occasional adjustment of the force and limit settings is normal. Weather conditions in particular can affect door travel.
The opener lights… 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 button and trolley will automatically reconnect (unless trolley is in lockout position.) See page 32.
2. The Outside Quick Release accessory (for use on garages with no service door) disconnects the trolley from outside the garage in case of power failure.
35
The door opens but won't close:
1. If the opener lights blink, check the safety reversing sensor. See page 22.
2. If the opener lights do not blink and it is a new installation, check the down force. See Adjustment Step 2, page 29. For an existing installation, see below.
Repeat the safety reverse test after the adjustment is complete.
Check the safety reversing sensor. Remove any obstruction or align the receiving eye. See pages 12 and 22.
