3. The door operates from the Control Console, but
not from the remote control:
• Is the door push bar flashing? If so, Lock mode is
engaged. Make sure it is off by pressing the
Lock button.
• Program the opener to match the remote control code.
(Refer to instructions on the motor unit panel.) Repeat
with all Remote.
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.
HAVING A PROBLEM?
(TROUBLESHOOTING)
1. The opener doesn't operate from either the Control
Console 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 7.
• 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 remote, but not from the
Control Console:
• Is the control console lit? If not, reverse the wires. If
the opener runs, check for a faulty wire connection at
the control console, a short under the staples, or a
broken wire.
• Are the wiring connections correct? Review Installation
