PROBABLE CAUSE & SOLUTION
OPENER DOESN’T OPERATE
FROM WALL CONTROL OR
TRANSMITTER
1. Have you disengaged all door locks? Review Step 8, page 14.
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 outl№ 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 touch­
ing both terminals at same time vrith a piece of metal (screwdriver or coin). If opener
runs, check for a faulty wire connection at Wall Control or a short under staples.
OPENER OPERATES FROM
TRANSMITTER BUT NOT
FROM WALL CONTROL
1. Is Wall Control push button lit? If not, refer to No. 5 above.
2. Are wiring connections correct? Review Step 6, page 13.
DOOR OPERATES FROM
WALL CONTROL BUT NOT
FROM THE TRANSMITTER
1. Does the battery test light glow when transmitter push button is pressed? If not,
replace the battery.
2. If you have two transmitters and only one operates, review the code setting
procedures on page 19. ALL transmitters must be set to same code.
3. Is transmitter(s) operating any other remote control devices? See the code setting
procedures on page 19.
4. Did you press the transmitter button designated to operate garage door opener?
5. Is the Lock Light ON? Turn it OFF.
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 right side 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 19.
2. Make sure 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 Control is faulty (replace), or there is a short or broken
wire between Wall Control arid opener.
DOOR DOESN’T OPEN
COMPLETELY
1. Is something obstructing the door?
2. If door opens at least 5 fieet, travel limits may need to be increased. One turn equals
2 inches of travel. See page 17.
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 17.
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 17,
REPEAT SAFETY REVERSE TEST after any adjustment of door arm length,
close force or down limit.
3. Door will not close after the Lock Light is turned ON.
DOOR WON’T CLOSE 1. The Infrared Reversing Sensor (if you have installed this accessory) may be mis­
aligned or obstructed. Disconnect sensor and check door operation. If the problem
