Having a Problem? Review Pages 2 and 3 Before Proceeding

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.

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.

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.

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.
