Install the Protector System
™
(See accessories)
The force, as measured on the closing edge of the door, should
not exceed 400 N (40kg). If the closing force is more than 400 N,
the Protector System must be installed.
After opener has been installed and adjusted, The Protector
System™ accessory can be installed. Instructions are included with
this accessory.
The Protector System™ provides an additional measure of safety
against a small child being caught under a garage door.
It uses an invisible beam which, when broken by an obstruction,
causes a closing door to open and prevents an open door from closing
and is strongly recommended for homeowners with young children.

HAVING A PROBLEM?
1. Opener doesn't operate from either door control or remote:
• Does the opener have electric power? Plug lamp into outlet. If it
doesn't light, check the fuse box or the circuit breaker. (Some outlets
are controlled by a wall switch.)
• Have you disengaged all door locks? Review installation instruction
warnings on page 1.
• Is there a build-up of ice or snow under door? The door may be
frozen to ground. Remove any obstruction.
• The garage door spring may be broken. Have it replaced.
2. Opener operates from remote but not from door control:
• Is door control button 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.
• Are wiring connections correct? Review page 4.
3. Door operates from door control but not from remote:
• Replace battery if necessary.
• If you have two or more remotes and only one operates, review
Program Your Opener, Remote and Keyless Entry steps 22 and 23.
• Is the door control button flashing? The opener is in lock mode. If you
have a Multi-Function Door Control, push and hold the Lock button
for 2 seconds. The door control button will stop flashing.
4. Remote has short range:
• Is battery installed?
• Change the location of the remote control on the car.
• Ametal garage door, foil-backed insulation or metal siding will reduce
the transmission range.
5. Door reverses for no apparent reason and opener light doesn't
blink:
• Is something obstructing the door? Pull manual release handle.
Operate door manually. If it is unbalanced or binding, call for
professional garage door service.
• Clear any ice or snow from garage floor area where garage
door closes.
• Repeat Setting Limits and Force, see adjustment steps 25 and 26.
Repeat safety reverse test after adjustment is complete.
6. Door reverses for no apparent reason and opener light blinks
for 5 seconds after reversing:
Check The Protector System™ (if you have installed this accessory).
If the light is blinking, correct alignment.
7. 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, Vibration Isolator Kit 41A3263 can be installed. This
kit was designed to reduce the "sounding board effect" and is easy to
install.
8. The garage door opens and closes by itself:
Make sure remote push button is not stuck "on".
9. Door stops but doesn't close completely:
Repeat Setting the Limits, see adjustment step 25.
Repeat safety reverse test after any adjustment of door arm length,
close force or down limit.
10. Door opens but won't close:
• Check The Protector System™ (if you have installed this accessory).
If the light is blinking, correct alignment.
• If opener light does not blink and it is a new installation, repeat
Setting the Limit and Force steps 25 and 26.
Repeat the safety reverse test after the adjustment is complete.
11. Opener light does not turn on:
Replace light bulb (24V/21W maximum). Replace burned out bulbs
with rough service light bulbs.
