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 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.
• 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, page 12.
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.
To Open the Door Manually
The door should be fully closed if
possible. Pull down on the
emergency release handle and lift
the door manually. To reconnect
the door to the opener, press the
door control push bar.
The lockout feature prevents the
trolley from reconnecting
automatically. Pull the emergency
release handle down and back
(toward the opener). The door can
then be raised and lowered
manually as often as necessary.
To disengage the lockout feature,
pull the handle straight down. The
trolley will reconnect on the next
UP or DOWN operation, either
manually or by using the door
control or remote.
To prevent possible SERIOUS INJURY or DEATH from a falling
garage door:
• If possible, use emergency release handle to disengage
trolley ONLY when garage door is CLOSED. Weak or broken
springs or unbalanced door could result in an open door
falling rapidly and/or unexpectedly.
• NEVER use emergency release handle unless garage
doorway is clear of persons and obstructions.
• NEVER use handle to pull door open or closed. If rope knot
becomes untied, you could fall.
