TROUBLESHOOTING
1. The opener doesn't operate from either the multi-
function 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.
