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, 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 7, page 21.

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.
