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 11.
• 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.
• Repeated operation may have tripped the overload
protector in the motor. Wait 15 minutes and try again.
2. Opener operates from the remote, but not from the
Door Control:
• Is the door control lit? If not, remove the bell wire from
the motor unit terminals. Short the red and white
terminals by touching both terminals at the same time
with a piece of wire. 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 18.
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.
