INSTALLATION STEP 9
Install The Protector System
®
Be sure power is not connected to the garage door opener
BEFORE installing the safety reversing sensor.
To prevent SERIOUS INJURY or DEATH from a closing
garage door:
• Correctly connect and align the safety reversing sensor.
This required safety device MUST NOT be disabled.
• Install the safety reversing sensor so beam is NO HIGHER
than 6" (15 cm) above garage floor.
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.
CAUTION
IMPORTANT INFORMATION ABOUT THE SAFETY
REVERSING SENSOR
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 amber
indicator light) transmits an invisible light beam to the
receiving eye (with a green indicator light). If an
obstruction breaks the light beam while the door is
closing, the door will stop and reverse to full open
position, and the opener lights will flash 10 times.
The units must be installed inside the garage so that the
sending and receiving eyes face each other across the
door, no more than 6" (15 cm) above the floor. Either can
be installed on the left or right of the door as long as the
sun never shines directly into the receiving eye lens.
The mounting brackets are designed to clip onto
the track of sectional garage doors without
additional hardware.
Safety Reversing Sensor
6" (15 cm) max.
above floor
If it is necessary to mount the units on the wall, the
brackets must be securely fastened to a solid surface
such as the wall framing. Extension brackets (see
accessories) are available if needed. If installing in
masonry construction, add a piece of wood at each
location to avoid drilling extra holes in masonry if
repositioning is necessary.
The invisible light beam path must be unobstructed. No
part of the garage door (or door tracks, springs, hinges,
rollers or other hardware) may interrupt the beam while
the door is closing.

TROUBLESHOOTING THE SAFETY
REVERSING SENSORS
1. If the sending eye indicator light does not glow steadily
after installation, check for:
• Electric power to the opener.
• A short in the white or white/black wires. These can
occur at staples, or at opener connections.
• Incorrect wiring between safety reversing sensors
and opener.
• A broken wire.
2. If the sending eye indicator light glows steadily but the
receiving eye indicator light doesn't:
• Check alignment.
• Check for an open wire to the receiving eye.
3. If the receiving eye indicator light is dim, realign
either sensor.
NOTE: When the invisible beam path is obstructed or
misaligned while the door is closing, the door will
reverse. If the door is already open, it will not close.
The opener lights will blink 10 times. (If bulbs are not
installed, 10 clicks can be heard.) See page 13.
ALIGNING THE SAFETY REVERSING SENSORS
• Plug in the opener. The indicator lights in both the
sending and receiving eyes will glow steadily if wiring
connections and alignment are correct.
The sending eye amber indicator light will glow
regardless of alignment or obstruction. If the green
indicator light in the receiving eye is off, dim, or flickering
(and the invisible light beam path is not obstructed),
alignment is required.
• Loosen the sending eye wing nut and readjust, aiming
directly at the receiving eye. Lock in place.
• Loosen the receiving eye wing nut and adjust the safety
reversing sensor until it receives the sender’s beam.
When the green indicator light glows steadily, tighten
the wing nut.

HAVING A PROBLEM?
(TROUBLESHOOTING)
1. The opener doesn't operate from either the Control
Console or the remote control:
• 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.)
• Have you disabled all door locks? Review installation
instruction warnings on page 7.
• 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.
3. The door operates from the Control Console, but
not from the remote control:
• Is the door push bar flashing? If so, Lock mode is
engaged. Make sure it is off by pressing the
Lock button.
• Program the opener to match the remote control code.
(Refer to instructions on the motor unit panel.) Repeat
with all Remote.
4. The remote control has short range:

• Check to be sure the antenna on the side or back
panel of motor unit extends fully downward.
• Some installations may have shorter range due to a
metal door, foil backed insulation, or metal
garage siding.
2. Opener operates from the remote, but not from the
Control Console:
• Is the control console lit? If not, reverse the wires. If
the opener runs, check for a faulty wire connection at
the control console, a short under the staples, or a
broken wire.
• Are the wiring connections correct? Review Installation
Step 5, page 10.
23
Having a Problem? (Continued)
5. The garage door opens and closes by itself:
• Be sure that all remote control push buttons are off.
• Remove the bell wire from the door control terminals
and operate from the remote only. If this solves the
problem, the door control is faulty (replace), or there
is an intermittent short on the wire between the
control console and the motor unit.
• Clear memory and re-program all remote controls.
10. The 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
opener and call a trained door systems technician.
11. The opener motor hums briefly, then won't work:
• The garage door springs may be broken. See above.
• If the problem occurs on the first operation of the
opener, door may be locked. Disable the power
door lock.
12. The opener won't operate due to power failure:
• Manually open the power door lock.
• Use the emergency release handle to disconnect the
door. The door can be opened and closed manually.
When power is restored, pull manual release a
second time.
• If a Battery Backup Unit is connected, the opener
should be able to operate up to 20 times
without power.
13. Door loses limits.
• Collar not tightened securely. Tighten collar

(see Adjustment Step 1).
14. The operator moves when the door is in
operation:
• Some minor movement is normal for this product. If it
is excessive the collar will wear prematurely.
• Check to make sure the torsion bar is not moving
left/right excessively.
• Check to make sure the torsion bar is not visibly
moving up and down as it rotates.
• Check that the operator is mounted at a right angle to
the jackshaft. If not, move the position of the
mounting bracket.
15. Power lock makes noise when operating.
• Call Liftmaster® dealer for replacement power lock.
6. The door doesn't open completely:
• Check power door lock.
• Is something obstructing the door? Is it out of
balance, or are the springs broken? Remove the
obstruction or repair the door.
7. The door opens but won't close:
• Check cable tension monitor.
• If the opener lights blink, check the safety reversing
sensor. See Installation Step 9.
• If the opener lights don’t blink and it is a new
installation. See Adjustment Step 2. For an existing
