1. The opener will not operate from either the UP/DOWN
activation button or the transmitters:
• Does the opener have electric power? Plug a lamp into the
outlet. If it does not work, check the fuse box.
• Have you disabled all door locks? Review the installation
safety instruction warnings on page 4.
• 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
by contacting a garage door repairer.
2. Opener operates from the transmitter, but not from the
wired wall control terminals:
• Check that the wiring connections are correct
.
3. The door operates from the UP/DOWN activation
buttons but not from the wireless wall control or
transmitter:
• Program the opener to match the transmitter code. Repeat
with all transmitters.
4. The transmitter has short range:
• Change the location of the transmitter.
• Check to be sure the antenna on the bottom of the opener
extends fully downward.
• Some installations may have shorter range due to a metal
door, foil backed insulation, or metal garage siding.
• The batteries may be flat. Replace the batteries.
5. The garage door opens and closes by itself:
• Be sure that no transmitter buttons are being pressed.
• Clear the memory and re-program all wireless wall controls
and transmitters.
6. The door reverses and stops before opening
completely:
•
Is something obstructing the door? Is it out of balance, or
are the springs broken? Remove the obstruction or repair
the door.
7. Door reverses for no apparent reason and opener
lights flash 10 times:
• Check The Protector System
TM
(IR Beams) (if you have
installed this accessory). If the red light on the beam is
flashing, the alignment is incorrect.
1. The door opens but will not close (or reverses while
closing):
• Is something obstructing the door? Pull the manual 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.
• Repeat the limit and force setting. Repeat safety reverse
test after adjustments.
2. The opener strains to operate the door:
• The door may be out of balance or the springs may be
broken. Close the door and use the manual release 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.
3. The opener motor hums briefly, then will not work:
• Check that the door is not in manual release mode (refer to
sections 9 or 10).
• The garage door springs may be broken.
• If the problem occurs on the first operation of the opener,
the door may be locked. Disable any door locks.
4. The opener will not operate due to a power failure:
• Use the manual release handle to disconnect the door.
The door can be opened and closed manually. When
power is restored, re-engage the opener to operate it via a
transmitter.
5. The LED Indicators on the control panel are flashing in
sequence:
• Check the diagnostic code in section 30.
