1. Does the opener have electric power? Plug a lamp into the outlet. If it doesn't light,
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 7.
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.
Having a Problem?
Situation Probable Cause & Solution
The opener doesn't
operate from either
the Door Control or
the remote control:
Opener operates from
the remote, but not
from Door Control:
1. Is the door control lit? If not, remove the bell wire from the opener terminals. 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 14.
The door operates
from the Door
Control, but not from
the remote control:
1. Is the door push bar flashing? If your model has the Lock feature, turn it
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:
The garage door
opens and closes
by itself:
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
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:
1. If the door has been working properly but now doesn't open all the way, increase the
up force.
See page 25.
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 24.
Repeat the safety reverse test after the adjustment is complete.
The door stops but
doesn't close
completely:
Review the travel limits adjustment procedures on page 24.
Repeat the safety reverse test after any adjustment of door arm length, close
force or down limit.
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.
Opener noise is
disturbing in living
quarters of home:
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.
