PROBABLE CAUSE & SOLUTION
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.
1. Is Wall Push Button lit? If not, refer to No. 5 above.
2. Are wiring connections correct? Review Step 5, page 14.
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 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?
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.
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.
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.
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.
