HAVING A PROBLEM?
1. The opener doesn't operate from either the Door
Control 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 3.
• 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.
2. Opener operates from the remote, but not from the
Door Control:
• Is the door control lit? If not, reverse the wires. If the
opener runs, check for a faulty wire connection at the
door control, a short under the staples, or a broken wire.
• Are the wiring connections correct? Review Installation
Step 6, page 17.
3. The door operates from the Door Control, but not
from the remote control:
• Is the door push bar flashing? If your model has the
Lock feature, make sure it is off.
• Program the opener to match the remote control code.
(Refer to instructions on the motor unit panel.) Repeat
with all remotes.
4. The remote control has short range:
• Change the location of the remote control in your car.
• 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.
5. 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 89LM can be installed. This kit was designed to
minimize vibration to the house and is easy to install.
6. 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 door
control and the motor unit.
• Clear memory and re-program all remote controls.
7. The door doesn't open completely:
• Is something obstructing the door? Is it out of balance,
or are the springs broken? Remove the obstruction or
repair the door.
8. The door opens but won't close:
• If the opener lights blink, check the safety reversing
sensor. See Installation Step 10.
• If the opener lights don’t blink 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.
9. The door reverses for no apparent reason and
opener lights don’t blink:
• 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 garage floor area where
the door closes.
• Review Adjustment Step 2.
Repeat safety reverse test after adjustments.
10. The door reverses for no apparent reason and
opener lights blink for 5 seconds after reversing:
• Check the safety reversing sensor. Remove any
obstruction or align the receiving eye. See Installation
Step 10.
11. The opener lights don't turn on:
• Replace the light bulbs (100 watts maximum). Use A19,
standard neck garage door opener bulbs for
replacement.
12. The opener lights don't turn off:
• Is the Light feature on? Turn it off.
13. 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 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 a
trained door systems technician.
14. 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 door lock.
15. The opener won't operate due to power failure:
• Use the emergency release handle to disconnect the
trolley. The door can be opened and closed manually.
When power is restored, press the Door Control push
bar and trolley will automatically reconnect (unless
trolley is in lockout position.) See page 31.
• 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.
