WARNING
• Failure to comply with the following instructions may result in serious personal injury or property damage.
• Read and follow all instructions carefully.
• The garage door opener is designed and tested to offer safe service provided it is installed and
operated in strict accordance with the instructions in this manual.
These safety alert symbols mean WARNING : A possible risk to personal safety or
property damage exists.
Keep garage door balanced. Do not let the garage
door opener compensate for a binding or sticking
garage door. Sticking, binding or unbalanced doors
must be repaired before installing this opener.
Do not wear rings, watches or loose clothing while
installing or servicing a garage door opener.
Frequently examine the door installation, in
particular cable, springs and mountings for signs
of wear, damage or imbalance. Do not use if repair
or adjustment is needed since springs and
hardware are under extreme tension and a fault
can cause serious personal injury.
To avoid serious personal injury from
entanglement, remove all ropes, chains and locks
connected to the garage door before installing the
door opener.
Installation and wiring must be in compliance with
your local building and electrical codes.
The safety reverse system test is very important. Your
garage door MUST reverse on contact with a
40mm obstacle placed on the floor. Failure to
properly adjust the opener may result in serious
personal injury from a closing garage door. Repeat
the test once a month and make any necessary
adjustments.

TROUBLESHOOTING THE SAFETY
REVERSING SENSORS
1.If the sending eye indicator LEDs are both flashing
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

appears to be too much pressure on the door,
you may toggle the door back and forth using
the black and orange buttons to reach the
desired position.
7. Push the transmitter, wireless wall button or the
multi-function door control (Figure 3). This sets
the DOWN (close) limit and should bring the
door to the open position.
• If the opener is not stopping exactly where you
would like it, repeat steps 1 through 7 and
program the limits again.
• When the unit stops in both the desired up
(open) and down (close) positions, proceed to
Adjustment Step 2, Setting the Force.
Without a properly installed safety reversal
system, persons (particularly children) could be
SERIOUSLY INJURED or KILLED by a closing

TROUBLESHOOTING
1. The opener doesn't operate from either the multifunction door control, wireless wall button or the
transmitter:
• 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 door spring may be broken. Have it replaced (see
page 5 for reference).
2. Opener operates from the transmitter, but not from
the Wireless Wall Button:
• Check the LED on the Wireless Wall Button to ensure
the LED turns on when button is pushed. If the LED is
weak or not on Change the batteries. (Remove cover
and replace with CR2032 batteries X 2)
• If the LED turns on and is strong check to ensure the
unit is programmed into the unit (see page 19).
3. The door operates from the multi-function door
control but not from the transmitter:
• Is the door push bar flashing? If so, Lock mode is
engaged. Make sure it is off by pressing the
Lock button for two seconds.
• Program the opener to match the transmitter code.
(Refer to instructions on the opener panel.) Repeat with
all Transmitter.
4. The transmitter has short range:
• Change the location of the transmitter in your car.
• Check to be sure the antenna on the side or back panel
of opener extends fully downward.
• Some installations may have shorter range due to a
metal door, foil backed insulation, or metal
siding.
5.The door opens and closes by itself:
• Be sure that all transmitter push buttons are off.
• Remove the bell wire from the mulit-function door
control terminals and operate from the transmitter only.
If this solves the problem, the multi-function door
control is faulty (replace), or there is an intermittent
short on the wire between the control console and the
opener.
• Clear memory and re-program all transmitters.
6. The door doesn't open completely:
• Check powered 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 (see installation step 4).
• If the opener LED is flashing, check the safety
reversing sensor. See Installation Step 8.
• If the opener LED is not flashing and it is a new
installation. See Adjustment Step 2. For an existing
installation, see below.
Repeat the safety reverse test after the adjustment
is complete.
8. The door reverses for no apparent reason and
opener LED doesn’t flash:
• Check cable tension monitor (see installation step 4).
• Is something obstructing the door? Pull the emergency
release handle. Operate the door manually. If it is
unbalanced or binding, call a trained door systems
technician.
• Clear any ice or snow from the floor area where the
door closes.
• Review Adjustment Step 2.
Repeat safety reverse test after adjustments.
9. The door reverses for no apparent reason and
opener LED flashes for 5 seconds after reversing:
• Check the safety reversing sensor. Remove any
obstruction or align the receiving eye. See Installation
Step 8.
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 door springs may be broken. See above.
• If the problem occurs on the first operation of the
opener, door may be locked. Disable the powered door
lock.
12.The opener won't operate due to power failure:
• Manually open the powered 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 an EverCharge 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 Assembly Steps 1 and 2) and reprogram limits
(see Adjustment Step 1).
14. The opener 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 opener 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 your local Merlin®dealer or Chamberlain customer
service for replacement power lock.

defects in materials or workmanship Chamberlain will,
provided the defective part or Unit is returned freight and
insurance prepaid and well packaged to the nearest
Chamberlain office or authorised installer, undertake to
repair or, at its option, replace any defective part or Unit
and return it to the Buyer at no cost. Repairs and
replacement parts are warranted for the remaining
portion of the original warranty period.
Limited warranty on opener
Chamberlain will furnish a replacement opener free of
charge, if it is found to be defective. Labour costs may
apply.
Where the Unit has been installed by an authorised
installer, Chamberlain will furnish replacement parts free
of charge through the authorised installer. A service fee
for on-site service may apply.
In-warranty service
During the warranty period, if the product appears as
though it may be defective, call our toll free service before
removal of the Unit. A Chamberlain technician will
diagnose the problem and promptly supply you with the
parts for “do-it-yourself” repairs, or provide you with
shipping instructions for a factory repair or replacement.
If an authorised installer installed your Unit you must call
them for prompt on-site service.
Liability – Australia only
Under no circumstances shall the Seller be liable for
consequential, incidental or special damages arising in
connection with the use, or inability to use, the Unit. In
no event shall the Seller's liability for damages or injury
arising from breach of law or contract or for negligence,
exceed the cost of repairing or replacing the Unit or
refunding the purchase price of the Unit.
Under Division 2 Part V of the Trade Practices Act, 1974,
certain warranties and conditions (Implied Terms) are
implied into contracts for the supply of goods or services
if the goods or services are of a kind ordinarily acquired
for personal, domestic or household use or consumption.
Liability for breach of those Implied Terms cannot be
excluded or limited and the limitations and exclusions
above do not apply to the Implied Terms.
Except for the Implied Terms and the warranties set out
above, the Seller excludes all warranties and conditions
implied by statute, at law, in fact or otherwise.
Liability – New Zealand only
Except as set out in the Fair Trading Act 1986 and the
Consumer Guarantees Act 1993:
(a) all other guarantees, warranties and representations
in relation to the Unit or its supply are excluded to the
extent that the Seller can lawfully exclude them; and
(b) under no circumstances shall the Seller be liable for
consequential, incidental or special damages arising in
connection with the use, or inability to use, the Unit, other
than those which were reasonably foreseeable as liable
to result from the failure.
