Power
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.
OPTION A: TYPICAL WIRING
1. Plug in the garage door opener into a grounded outlet.
2. DO NOT run garage door opener at this time.
OPTION B: PERMANENT WIRING CONNECTION
If permanent wiring is required by your local code, refer to
the following procedure.
To make a permanent connection through the 7/8 inch hole
in the back of the garage door opener (according to local
code):
1. Be sure power is NOT connected to the opener, and
disconnect power to circuit.
2. Remove the garage door opener from the torsion bar,
remove cover screws and set the cover aside.
3. Cut the line cord 6" (15.2 cm) above the strain relief.
4. Squeeze the strain relief and push into motor unit,
then remove the strain relief from the line cord.
5. Install a 90° conduit (not provided) or flex cable
adapter (not provided) to the 7/8" hole. Reinstall
garage door opener to torsion bar.
6. Run wires through conduit, cut to proper length and
strip insulation.
7. Strip 1/2" (1.3 cm) of insulation from the existing
black, white and green wires.
8. Connect the line to the black wire and neutral to the
white wire with wire nuts (not provided). Connect
ground wire to the green ground screw.
9. Properly secure wires under plastic ties so that they
do not come into contact with moving parts.
10. Reinstall cover.
To prevent possible SERIOUS INJURY or DEATH from
electrocution or fire:
• Be sure power is NOT connected to the opener, and
disconnect power to circuit BEFORE removing cover
to establish permanent wiring connection.
• Garage door installation and wiring MUST be in
compliance with ALL local electrical and building
codes.
• NEVER use an extension cord, 2-wire adapter or
change plug in ANY way to make it fit outlet. Be sure
the opener is grounded.

Battery Backup
The battery backup allows access in and out of your garage
when the power is out. When the garage door opener is
operating on battery power, the garage door opener will
run slower and the lights, Timer-to-Close, and remote
close features (myQ App) are disabled. In battery backup
mode, the Automatic Garage Door Lock will unlock when
the garage door is opened, and will remain disabled until
power is restored. During a power outage the battery
supplies power for up to 24 hours of operation. For
maximum battery life and prevent damage, disconnect the
battery when the garage door opener is unplugged for an
extended period of time.

Operation
Be sure power is NOT connected to the garage door
opener BEFORE installing the safety reversing sensor.
To prevent SERIOUS INJURY or DEATH from closing
garage door:
• Correctly connect and align the safety reversing
sensor. This required safety device MUST NOT be
disabled.
• Install the safety reversing sensor so beam is NO
HIGHER than 6" (15 cm) above garage floor.
The Protector System® (Safety Reversing Sensors)
The door will not close if the sensors have not been
installed and aligned correctly.
When the light beam is obstructed or misaligned while the
door is closing, the door will reverse. If the door is already
open, it will not close.
The sensors can be aligned by loosening the wing nuts,
aligning the sensors, and tightening the wing nuts. Check
to make sure the LEDs in both sensors are glowing
steadily. The LEDs in both sensors will glow steadily if they
are aligned and wired correctly.
If either of the sensor LEDs are off, there is no power to the sensor:
1. Check that you have power to the garage door opener.
2. Check the sensor wire is not shorted or broken.
3. Check that the sensors are wired correctly; white wires to white terminal and white/black wires to grey terminal.
If the green receiving sensor LED is blinking, the sensors are obstructed or misaligned:
1. Check for obstructions in the sensor light beam.
2. Align the sensors.
3. If the receiving sensor (green LED) faces direct sunlight, switch the sensors to opposite sides of the door to assure
proper operation.

Adjustment
Introduction
Without a properly installed safety reversal system,
persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage
door.
• Incorrect adjustment of garage door travel limits
will interfere with proper operation of safety reversal
system.
• After ANY adjustments are made, the safety reversal
system MUST be tested. Door MUST reverse on
contact with 1-1/2" (3.8 cm) high object (or 2x4 laid
flat) on floor.
Your garage door opener is designed with electronic
controls to make setup and adjustments easy. The
adjustments allow you to program where the door will
stop in the open (UP) and close (DOWN) position. The
electronic controls sense the amount of force required to
open and close the door.
NOTE: If anything interferes with the door’s upward travel
it will stop. If anything interferes with the door’s downward
travel, it will reverse.
To prevent damage to vehicles, be sure fully open door
provides adequate clearance.

Troubleshooting
The garage door opener doesn't operate from either the door control or the remote control:
• Does the garage door opener have electric power? Plug a lamp into the outlet. If it doesn't light, check the fuse box or the circuit
breaker. (Some outlets are controlled by a wall switch.)
• Have you disabled all door locks? Review installation instruction warnings on page 8.
• Are the wiring connections correct? Review Installation Step 5.
• Is there a build-up of ice or snow under the door? The door may be frozen to the ground. Remove any restriction.
• The garage door spring may be broken. Have it replaced (see page 3 for reference).
The door opener operates from the single button control station, but not from a remote control:
• Reprogram the remote control and replace the battery if necessary. Repeat with all remote controls.
The door opens and closes byitself:
• Be sure that all remote control push buttons are off.
• Remove the bell wire from the single button control station terminals and operate from the remote only. If this solves the problem,
the single button control station is faulty, or there is an intermittent short in the wire. Replace the control station.
• Erase the memory and reprogram all remote controls (refer to the instructions provided with the remote control or visit
LiftMaster.com/Customer-Support).
My remote control will not activate the garage door:
• Verify the lock feature is not activated on the door control.
• Reprogram the remote control.
• If the remote control will still not activate the door check the diagnostic codes to ensure the garage door opener is working
properly.
The remote control has short range:
• Change the location of the remote control in your car.
• Some installations may have shorter range due to a metal door, foil backed insulation, or metal garage siding.
The door stops or reverses to open limit and the opener beeps and lights flash 5 times:
• Is something obstructing the door? Is it out of balance, or are the springs broken? Remove the obstruction or call a trained door
system technician to repair the door.
The door doesn't open completely:
• Check power door lock.
The door opens but won't close:
• The safety reversing sensor must be connected and aligned correctly before the door opener will move in the down direction. If you
are able to close the door using constant pressure, verify the safety reversing sensors are properly installed, aligned and free of any
obstructions (see page 13).
The door reverses for no apparent reason:
• Clear any ice or snow from the garage floor area where the door closes.
• Review Adjustment Step 3.
Repeat safety reverse test after adjustments.
My door will not close:
• The safety reversing sensor must be connected and aligned correctly before the garage door opener will move in the down
direction.
- Verify the safety reversing sensors are properly installed, aligned and free of any obstructions.
The garage door opener strains to operate door:
• The door may be out of balance or the springs may be broken. Close the door and use the emergency release handle to disconnect
the door. 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 garage door opener and call a trained door systems technician.
The garage door opener motor hums briefly, then won't work:
• The garage door springs may be broken. See above.
• If the problem occurs on the first operation of the garage door opener, door may be locked. Disable the power door lock.
The garage door opener won't operate due to power failure:
• Manually open the power door lock.
Cable unspooling upon obstruction near top limit:
• If cable unspools, please contacta Professional Door Dealer for service.
