MAINTENANCE OF YOUR OPENER
Once a Month:

• Manually operate door. If it is unbalanced or binding, call for
professional garage door service.
• Check to be sure door opens and closes fully. Adjust Limits and/or
Force if necessary.
Twice a Year:
• Check chain tension. Disconnect trolley first. Adjust if necessary.
Once a Year:
Oil door rollers, bearings and hinges. The opener does not require
additional lubrication. Do not grease the door tracks.
HAVING A PROBLEM?
1. Opener doesn't operate from remote control:
• 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 the door? The door may be
frozen to ground. Remove any obstruction.
• The garage door spring may be broken. Have it replaced.
• Repeated operation may have tripped the overload protector in the
motor. Wait 15 minutes. Try again.
2. Remote has short range:
• Is battery installed? Check battery test light. If the light is dim,
change the battery.
• 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.
3. 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.
• Review Force Adjustment.
• If door reverses in FULLY CLOSED position, decrease travel limits.
Repeat safety reverse test after adjustment is complete.
The need for occasional adjustment of the force and limit
settings is normal. Weather conditions in particular can affect
door travel.
4. 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.
5. 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 eliminate the "sounding board effect" and is
easy to install.

6. The garage door opens and closes by itself:
• Is there a neighbor with a garage door opener using the same
frequency code? Change your code.
• Make sure remote push button is not stuck "on".
7. Door stops but doesn't close completely:
Review Travel Limits Adjustment.
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 blinking, correct alignment.
• If opener light does not blink and it is a new installation, check the
down force.
Repeat the safety reverse test after the adjustment is complete.
9. Opener light does not turn ON:
Replace light bulb (40 Watts maximum). Replace burned out light
bulbs with rough service light bulbs.
10. Opener light does not turn OFF:
There may be a defective earth at the ceiling or wall receptacle.
The unit must be earthed.
11. Opener strains or maximum force is needed to activate door:
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.
Do not increase the force to operate the opener.
12. Opener motor 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. If chain was removed and reinstalled, the motor
may be out of phase. Remove chain; cycle motor to down position.
Observe drive sprocket. When it turns in clockwise direction and
stops in down position, re-install chain.
Repeat safety reverse test after adjustment is complete.
13. Opener won't activate due to power failure:
• Pull manual release rope and handle down and back to disconnect
trolley. Door can be opened and closed manually. When the power is
restored, pull the manual release handle straight down. The next
time the opener is activated, the trolley will reconnect.
• The Outside Quick Release accessory 1702EML (if fitted)
disconnects the trolley from outside the garage in case of power
failure.
14. The chain droops or sags:
It is normal for the chain to droop slightly in the closed door position.
Use the manual release rope and handle to disconnect the trolley. If
the chain returns to the normal height when the trolley is disengaged
and the door reverses on a 50mm obstacle laid flat, no adjustments
are needed.
