10. Opener strains:

Door may be unbalanced or springs are broken. Close

door and use manual release rope and handle to

disconnect trolley. Open and close door manually. A

properly balanced door will stay in any point of travel

while being supported entirely by its springs. If it does

not, call for professional garage door service to correct

the problem.

11. Opener hums briefly, then won't work:

• Garage door springs are broken. SEE ABOVE.

• If problem occurs on first operation of opener, door is

locked. Disable door lock.

Repeat safety reverse test after adjustment is complete.

12. Opener won't activate due to power failure:

• Check battery backup system on page 19.

• Pull manual release rope and handle down to

disconnect trolley. Door can be opened and closed

manually. When the power is restored, pull the manual

release handle down and toward opener. The next time

the opener is activated, the trolley will re-connect.

• The Outside Quick Release accessory (if fitted)

disconnects the trolley from outside the garage in case

of power failure.

13. Setting the limits manually:

1. Press and hold the black button until the orange

indicator light starts flashing slowly then release.

2. Adjust the position of the door by using the black and

orange buttons. Black moves the door UP (open) and

orange moves the door DOWN (close).

Check to be sure the door opens high enough for your

vehicle.

3. Push the remote control or door control. This sets the

UP (open) limit and begins closing the door.

Immediately press either the orange or the black

button.

The door will stop.

Adjust the desired DOWN (close) limit position using

the black and orange buttons. Check to be sure the

door is fully closed without applying excessive pressure

on the rail (rail should not bow upwards and the belt

should not sag or droop below the rail). Push the

remote control or door control. This sets the DOWN

(close) limit and begins opening the door.

NOTE: If neither the black or the orange button is

pressed, the door will reverse off the floor and the

DOWN travel limit will be set automatically.

4. Open and close the door with the remote control or

door control 2 or 3 times.

• If the door does not stop in the desired UP (open)

position or reverses before the door stops at the DOWN

(close) position, repeat Setting the Limits and Force,

refer to pages 20 and 21

.

• If the door stops in both the desired UP (open) and

DOWN (close) positions, proceed to Test the Safety

Reversal System, refer page 22.

TROUBLE SHOOTING

1. Opener doesn't operate from either door control or

remote:

• Does the opener have electric or battery 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.

• Check battery LED for status, refer page 19.

2. Opener will not operate from the LCD Motion

Detecting control:

• Is door control LCD 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 16.

3. Door operates from door control but not from

remote:

• Replace batteries in the remote if necessary.

• If you have two or more remotes and only one operates,

review Program Your Opener, Remote and Keyless

Entry pages 24 and 25.

• Is the Locked mode displayed on the LCD? The opener

is in lock mode. Push and hold the Lock button for 2

seconds.

4. Remote has short range:

• Check the battery in the remote is fully charged.

• Change the location of the remote control on the car.

• A metal garage door, foil-backed insulation or metal

siding will reduce the transmission range.

5. Door reverses for no apparent reason and opener

light flashes for 5 seconds after reversing:

Check The Protector System™ (if you have installed this

accessory). If the light is flashing, correct alignment.

6. The garage door opens and closes by itself:

Make sure remote push button is not stuck "on".

7. Door stops but doesn't close completely:

Repeat Setting the Limits, refer page 20.

Repeat safety reverse test after any adjustment of door

arm length, close force or down limit.

8. Door opens but won't close:

• Check The Protector System™ (if you have installed this

accessory). If the light is flashing, correct alignment.

• If opener light does not flash and it is a new installation,

repeat Setting the Limit and Force pages 20 and 21.

Repeat the safety reverse test after the adjustment is

complete.

9. Opener lights do not turn on:

Unit may be operating on battery power.

• Check battery status LED, refer page 19.

• Replace light bulb (230V/40W maximum) or energy

saving Halogen light bulbs (28W/40W).
