Troubleshooting - Merlin WeatherDrive MR550EVO Installation And Operating Instructions Manual

TROUBLESHOOTING

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 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 transmitter, but not
from the wired wall control terminals:
• Are the wiring connections 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 in your car.
• 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.
5. The garage door opens and closes by itself:
• Be sure that all transmitter push buttons are off.
• If the wired wall control terminals are installed, remove
the bell wire from the wired wall control terminals and
operate from the ACTIVATION button or transmitter . If
this solves the problem, the wired wall control is faulty
(replace), or there is an intermittent short on the wire
between the wired wall control and the opener.
• Clear 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
• Check The Protector System™ (if you have installed
opener lights flashes 10 times:
this accessory). If the red light on the beam is flashing,
the alignment is incorrect.
• The red light on the beams may not be on if the
opener is in Standby mode. Activate the door to
temporarily exit standby mode and check lights are on
constantly. If the LEDs are flashing, realign the beams.
8. The door opens but will not close or reverses
while closing (refer to point 7 as well):
• 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.
9. 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 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.
10. The opener motor hums briefly, then will not
work:
• Check that the door is not in manual release mode
(refer section 8).
• 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 any door locks.
11. The opener will not operate due to power
failure:
• Use the manual release handle to disconnect the
door. The door can be opened and closed manually.
