ATTEMPT TO LOOSEN, MOVE OR ADJUST
THEM. Call for garage door service.
THE SAFETY REVERSE SYSTEM TEST IS
VERY IMPORTANT (page 22). Your garage door
MUST reverse on contact with a 1-inch obstacle
placed on the floor. Failure to properly adjust
the opener may result in serious personal injury
from a closing garage door. REPEAT THE TEST
ONCE A MONTH AND MAKE ANY NEEDED
ADJUSTMENTS.
DO NOT WEARE RINGS, WATCHES OR
LOOSE CLOTHING while installing or servicing
a garage door opener.
DO NOT USE THE FORCE ADJUSTMENTS
TO COMPENSATE FOR A BINDING OR
STICKING GARAGE DOOR. Excessive

CARE OF THE OPENER
When properly installed, opener will provide high
performance with a minimum of maintenance. The
opener does not require additional lubrication.
CHAIN TENSION ADJUSTMENT: After installation of
the opener and adjustment of forces and limits, the
chain may appear loose. This is normal.
Most complaints of unsatisfactory opener operation can
be traced to problems with the door itself. When
operated manually, a properly balanced door will stay in
any point of travel while being supported entirely by its
springs.
TO CHECK THE CHAIN TENSION: Disconnect the
trolley by pulling the red emergency handle. If the chain
returns to the position described and illustrated in Step 4
page 9, DO NOT make ANY further adjustments.
TRANSMITTER: The 3-function transmitter will operate
more than one garage door opener, if desired. The push
buttons may also be used to operate other 18000SR
Series garage door openers and light products, Models
18727 and 18725. The standard transmitter may be
secured to car sun visor with clip provided. Additional
transmitters can be purchased at any time. Refer to
Accessories on page 5.
THE OPENER IS NOT INTENDED TO CORRECT
ANY PROBLEMS THAT ARE CAUSED BY AN
UNBALANCED OR BINDING DOOR, BROKEN
DOOR SPRINGS OR BY FAULTY DOOR
HARDWARE.
LIMIT AND FORCE ADJUSTMENTS: These
adjustments must be checked and properly set when
opener is installed. Only a screwdriver is required.
Pages 20 and 21 refer to the limit and force
adjustments. Follow the instructions carefully.
Any new transmitter must be set to the same code as
the original transmitter. Page 23 explains how to change
your existing code and use the transmitter(s) with the
other receivers mentioned above. Self service of your
radio controls is not recommended. If service is needed,
contact your nearest Sears Service Center.
REPEAT THE SAFETY REVERSE TEST AFTER ANY
ADJUSTMENT. Weather conditions may cause
some minor changes in the door operation,
requiring some readjustments, particularly during
the first year of operation.
TRANSMITTER BATTERY: The 12 Volt battery should
produce power for at least one year. As long as there is
adequate power, the transmitter battery test light will
glow when the push button is pressed (and the opener
or other control will operate). If light does not come on,
replace the battery. If transmission range lessens, check
the battery test light.
THE SAFETY REVERSE SYSTEM IS IMPORTANT
(SEE Pg. 22). GARAGE DOOR MUST REVERSE ON
CONTACT WITH A 1-INCH OBSTACLE PLACED ON
THE FLOOR. FAILURE TO PROPERLY ADJUST
OPENER MAY RESULT IN SERIOUS PERSONAL
INJURY FROM A CLOSING GARAGE DOOR.
TO CHANGE BATTERY: Slide the battery
compartment cover back. Remove old battery and
position and new 12 Volt battery as directed.

Having a Problem?
Review Pages 2 and 3 Before Proceeding
SITUATION
PROBABLE CAUSE & SOLUTION
OPENER DOESN'T OPERATE
FROM WALL PUSH BUTTON
OR TRANSMITTER
1. Have you disengaged all door locks? Review Step 8, page 16.
2. Does the opener have electric power? Plug a lamp into the outlet. If it doesn't light,
check fuse box or circuit breaker. (Some outlets are controlled by a wall switch.)
3. Repeated operation may have tripped the overload protector in the motor. Wait 15
minutes. Try again.
4. Is there a build-up of ice or snow under door? Door may be frozen to ground.
Remove any obstruction.
5. Remove bell wire from opener terminals. Short red and white terminals by touching
both terminals at same time with a piece of metal (screwdriver or coin). If opener
runs, check for a faulty wire connection at Wall Push Button or a short under staples.
OPENER OPERATES FROM
TRANSMITTER BUT NOT FROM
WALL PUSH BUTTON
1. Is Wall Push Button lit? If not, refer to No. 5 above.
DOOR OPERATES FROM WALL
PUSH BUTTON BUT NOT
FROM THE TRANSMITTER
1. Does the battery test light glow when transmitter push button is pressed? If not,
replace the battery.
2. Are wiring connections correct? Review Step 5, page 14.
2. If you have two transmitters and only one operates, review the code setting
procedures on page 23. ALL transmitters must be set to same code.
3. Is transmitter(s) operating any other remote control devices? See the code setting
prcedures on page 23.
4. Did you press the transmitter button designated to operate garage door opener?
TRANSMITTER HAS
SHORT RANGE
1. Check battery test light. If the light is dim, change the battery.
2. Change the location of the transmitter in the car.
3. A metal garage door, foil-backed insulation or metal siding will reduce the
transmission range. An antenna extender kit is available from any Sears store or
service center.
4. Check to be sure antenna on the rear panel of opener extends fully downward.
THE GARAGE DOOR OPENS
AND CLOSES BY ITSELF
1. Is there a neighbor with a garage door opener using the same frequency code?
Change your code. Review page 23.
2. Make sure that none of the transmitter push buttons is stuck in the "down" position.
3. Remove bell wire from opener terminals and operate from transmitter only. If this
solves the problem, the Wall Push Button is faulty (replace), or there is a short or
broken wire between Wall Push Button and opener.
DOOR DOESN'T OPEN
COMPLETELY
1. Is something obstructing the door?
2. If door opens at least 5 feet, travel limits may need to be increased. One turn equals
2 inches of travel. See page 20.
REPEAT SAFETY REVERSE TEST after the adjustment is complete.
3. If door has been working properly but now doesn't open all the way, increase the
UP FORCE. See page 21.
REPEAT SAFETY REVERSE TEST after the adjustment is complete.
DOOR DOESN'T CLOSE
COMPLETELY
1. Is something obstructing the door?
2. Review the Travel Limits Adjustment Chart on page 20.
REPEAT SAFETY REVERSE TEST after any adjustment of door arm length,
close force or down limit.
24
Having a Problem?
(Continued)
SITUATION
PROBABLE CAUSE & SOLUTION
DOOR REVERSES FOR NO
APPARENT REASON
1. Is something obstructing the door? Pull red emergency release handle. Operate
door manually. If it is unbalanced or binding, call for professional garage door
service.
2. Clear any ice or snow from garage floor area where garage door closes.
3. Review the Force Adjustment Chart on page 21.
REPEAT SAFETY REVERSE TEST after adjustment is complete.
4. If door reverses in FULLY CLOSED position, decrease travel limits (Page 20).
REPEAT SAFETY REVERSE TEST after the adjustment is complete. THE
NEED FOR OCCASIONAL ADJUSTMENT OF THE FORCE AND LIMIT
SETTINGS IS NORMAL. WEATHER CONDITIONS IN PARTICULAR CAN
AFFECT DOOR TRAVEL.
OPENER LIGHT
DOES NOT TURN ON
1. Replace the light bulb (75 watts maximum). Use a "garage door opener bulb" if
standard bulb burns out prematurely due to vibration. Vibration may be caused
by loose end panel. Retighten screws.
DOES NOT TURN OFF
1. There may be a defective ground at ceiling or wall receptacle.
UNIT MUST BE GROUNDED.
OPENER STRAINS OR MAXIMUM
FORCE IS NEEDED TO OPERATE
DOOR
1. Door may be out of balance or springs are broken. Close door and use
emergency release rope and handle to disconnect trolley. Open and close door
manually. A properly balanced door will stay in any point of travel while being
supported entirely by its springs. If it does not, call for professional garage door
service.
OPENER MOTOR HUMS
BRIEFLY, THEN WON'T WORK
1. Garage door springs are broken. SEE ABOVE.
2. The trolley may be jammed into stop bolts. Pull or push on door while motor is
humming to release jammed condition. Re-adjust door limits (page 20) to
prevent over-travel.
REPEAT SAFETY REVERSE TEST after adjustment is complete.
3. If the problem occurs on first operation of the opener, door is locked. DISABLE
DOOR LOCK. If chain was removed and reinstalled, motor may be out of phase.
Remove chain; cycle motor to the down position. Observe drive sprocket. When
it turns in clockwise direction and stops in down position, reinstall chain.
REPEAT SAFETY REVERSE TEST after adjustment is complete.
OPENER WON'T OPERATE DUE
TO POWER FAILURE
1. Use emergency release rope and handle to disconnect trolley. Door can be
opened and closed manually. When the power is restored, press the Wall Push
Button and trolley will automatically reconnect. Refer to Page 5 for "Lockout"
feature.
2. The emergency release Key Lock accessory (for use on garages with no service
door) disconnects the trolley from outside the garage in case of power failure.
CHAIN DROOPS OR SAGS
1. It is normal for chain to droop slightly in the closed door position. Use emergency
release rope and handle to disconnect trolley. If chain returns to normal height
when the trolley is disengaged and door reverses on a one-inch obstruction, no
adjustments are needed (see page 9).
OPENER NOISE IS DISTURBING
IN LIVING QUARTERS OF HOME
1. If operational noise is a problem because of proximity of the opener to the living
quarters, Vibration Isolator Kit 41A3263 can be ordered from any Sears Service
Center and most Sears Stores. This kit was designed to eliminate the "sounding
board effect" and is easy to install.
