Having a Problem?
Probable Cause & Solution
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 10.
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.
1. Is the door control button 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 16.
1. Does the battery test light glow when the remote control push button is pressed? If
not, replace the battery.
2. Program the receiver to match the remote control code.
3. Repeat the receiver programming procedure with all remote controls.
1. Check the battery test light. If the light is dim, change the battery.
2. Change the location of the remote control in your car.
3. Check to be sure the antenna on the back panel of opener extends fully downward.
4. Some installations may have shorter range due to a metal door, foil backed
insulation, or metal garage siding.
Install Antenna Kit, Part No. 41A3504, to increase range.
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 and battery indicator lights 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.
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.
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.
