SITUATION PROBABLE CAUSE & SOLUTION
OPENER DOESN'T OPERATE
FROM EITHER THE DOOR
CONTROL BUTTON OR REMOTE
CONTROL TRANSMITTER
1. Have you disengaged all door locks? Review Step 7, 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 door control button or a short under staples.
OPENER OPERATES FROM
REMOTE CONTROL BUT
NOT FROM DOOR CONTROL
BUTTON
1. Is door control push button lit? If not, refer to No. 5 above and follow same procedure.
2. Are wiring connections correct? Review Step 5, page 14 or 15.
DOOR OPERATES FROM
DOOR CONTROL PUSH BUTTON
BUT NOT FROM THE REMOTE
CONTROL TRANSMITTER
1. Is the LOCK Switch ON? (Models 1160 and 1150) Turn it OFF.
2. Does the battery test light glow when remote control push button is pressed? If not, replace
the battery.
3. If you have two remote controls and only one operates, review the code setting procedures on
page 23. ALL remote controls must be set to same code.
REMOTE CONTROL TRANSMITTER
HAS SHORT RANGE
1. Check battery test light. If the light is dim, change the battery.
2. Change the location of the remote control in the car.
3. A metal garage door or foil-backed insulation or metal siding will reduce the transmission
range.
4. Check to be sure antenna on the back 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. Check to be sure that the remote control push button is not stuck in the 'down' position.
3. Remove bell wire from opener terminals and operate from remote control only. If this solves
the problem, the door control is faulty (replace), or there is a short or broken wire between door
control 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.
DOOR WON'T CLOSE
1. Check the Protector System (if you have installed this accessory). If the light is blinking,
correct alignment.
