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 15.
• 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, 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.
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.
