Situation

The opener doesn't

operate from either the Door Control or

the remote control:

Having a Problem?

Probable Cause and Solution

1.Does the opener have electric power? Plug a lamp into the outlet. If it doesn'tlight, check the fuse box or the circuit breaker. (Some outlets are controlled by a wall switch.)

2.Have you disabled all door locks? Review installation instruction warnings on Page 11.

3.Is there a build-up of ice or snow under the door? The door may be frozen to the ground. Remove any restriction.

4.The garage door spring may be broken. Have it replaced.

5.Repeated operation may have tripped the overload protector in the motor. Wait 15 minutes. Try again.

Opener operates from the remote

control, but not from

the Door Control:

The door operates from the Door

Control, but not from

the remote control:

1.Is the Door Control lit? If not, remove the bell wire from the opener terminal screws. Short the red and white terminals by touching both terminals at the same time with a

piece of wire. If the opener runs, check for a faulty wire connection at the Door Control, a short under the staples, or a broken wire.

2.Are the wiring connections correct? Review Step 6; page 18.

1.Is any door push button flashing? If your model has the Lock feature, make sure the lock is Off.

2.Your opener needs to re-learn a remote control code. Refer to Instructions on the opener panel.

3.Program the receiver to match the remote control code.

4.Repeat the receiver programming procedure with all remote controls.

The remote control has short range:

1.Change the location of the remote control in your car.

2.Check to be sure the antenna on the side or back panel of opener extends fully downward.

3.Some installations may have shorter range due to a metal door, foil backed insulation, or metal garage siding. (Antenna Extender Kit 41A3504)

Opener noise is disturbing in living quarters of home:

The garage door opens and closes by itself,"

If operational noise is a problem because of proximity of the opener to the living quarters, the Vibration Isolator Kit 41A3263 can be installed. This kit was designed to minimize vibration to the house and is easy to install.

1.Be sure that all remote control push buttons are off.

2.Remove the bell wire from the Door Control terminals and operate from the remote control only. If this solves the problem, the Door Control is faulty (replace), or there is an intermittent short on the wire between the Door Control and the opener.

3.Clear memory and reprogram all remote controls.

The door doesn't open completely:

The door stops but doesn't close

completely:

1.If the door has been working properly but now doesn't open all the way, increase the up force. See page 29.

2.Is something obstructing the door? Remove the obstruction or repair the door.

3.If door opens at least 5 feet, the travel limits may need to be increased. One turn equals 2 inches of travel. See page 28.

Repeat the safety reverse test after the adjustment is complete.

Review the travel limits adjustment procedures on page 28.

Repeat the safety reverse test after any adjustment of door arm length, close force or down limit.
