Care of Your Opener
LIMIT AND FORCE ADJUSTMENTS:
Weather conditions may cause
some minor changes in door
operation requiring some
readjustments, particularly
during the first year of operation.
Pages 28 and 29 refer to the
limit and force adjustments.
Only a screwdriver is required.
Follow the instructions carefully.
Repeat the safety reverse test
(page 30) after any adjustment
of limits or force.
MAINTENANCE SCHEDULE
Once a Month
• Manually operate door. If it is unbalanced or
binding, call a trained door systems technician.
• Check to be sure door opens & closes fully. Adjust
limits and/or force if necessary (See pages 28
and 29).
• Repeat the safety reverse test. Make any
necessary adjustments (See page 30).
Twice a Year
• Check chain tension. Disconnect trolley first. Adjust
if necessary (see page 11).
Once a Year
• Oil door rollers, bearings and hinges. The opener
does not require additional lubrication. Do not
grease the door tracks.
THE REMOTE CONTROL BATTERY
The lithium battery should
produce power for up to
5 years. To replace battery, use
the visor clip or screwdriver
blade to pry open the case as
shown. Insert battery positive
side up.
Dispose of old battery properly.
Having a Problem?
1. The opener does not 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.
