TROUBLE SHOOTING
7. Door opens but won't close:
• Check The Protector System™ (if you have installed
this accessory). If the light on the Beams are flashing,
correct the alignment.
• If opener light does not flash and it is a new installation,
repeat Programming the Travel Limits.
Repeat the safety reverse test after the adjustment is
complete.
8. 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.
9. 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.
10. Opener won't activate due to power failure:
• 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 rope back towards the motor until it springs
back to its original horizontal position. 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.
11. The opener runs, but the carriage does not move:
• Check the carriage is not disengaged from the opener.
Operate the manual release to reengage the opener.
• In a new installation, the preassembled Motor Shaft
Adapter may have fallen out of the chain sprocket
assembly. This adapter is installed during the
manufacturing process and may have dislodged.
12. The Up and DOWN arrows on the control panel
are flashing in sequence:
Check the diagnostic code on next page.
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. 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.
3. Remote has short range:
• Check the battery in the remote is fully charged.
• Change the location of the remote control in the car.
• A metal garage door, foil-backed insulation or metal
siding will reduce the transmission range.
4. Door reverses for no apparent reason and opener
light flashes 10 times:
• Check The Protector System™ (if you have installed this
accessory). If the light is flashing, correct the alignment.
If the Protector System
TM
is installed and needs to be
removed, the Opener will need to be reprogrammed as
follows:
• Remove the IR Beam wiring from the Opener.
• Turn the power OFF for 5 seconds.
• Turn the power ON for 5 seconds.
• Again turn the power OFF for 5 seconds.
• Turn the power back on and test the opener for normal
operation.
5. The garage door opens and closes by itself:
Make sure remote push button is not stuck "on".
6. Door stops but doesn't close completely:
Repeat Programming the Travel Limits.
Repeat safety reverse test after any adjustment of door
arm length, close force or down limit adjustments.
