Chamberlain 1146 Garage Door Opener User Manual


 
Troubleshooting
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.
Repeated operation may have tripped the overload protector
in the motor. Wait 15 minutes. Try again.
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 3.
3. Door operates from door control but not from remote:
• Check battery. Replace battery if necessary.
• Is the light at the wall control flashing? Press button with
key-symbol to unlock the opener against remote controls.
• Is the receiver LED flashing at the back-side of the opener
when the transmitter is pressed? The opener receiver must
re-learn the remote control code. Follow the instructions on
page 4.
• If you purchased a new remote control then check at carton
of remote control for compatibility or call the Service Hotline.
4. Remote has short range:
Is battery installed? If needed, 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.
• Use outside coaxial antenna adapter to move antenna.
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.
• Review Force Settings. Open and close the door in learn
mode for several (3-5) consecutive cycles to allow the
operator to adjust to inconsistent doors.
• If door reverses in FULLY CLOSED position, re-learn travel
limits.
Repeat safety reverse test after adjustment is complete.
The need for occasional adjustment of the force and limit
settings is normal. W
eather conditions in particular can affect
door travel.
6.
Door reverses for no apparent reason and opener light
blinks for 5 seconds after reversing:
Check
The Safety Infrared Reversing Sensor (if you have
installed this accessory). If the light is blinking, correct
alignment.
Note: Continuously holding down the door control button will
allow the door to close if the protector system is not properly
aligned. The transmitter will not close the door. The opener
lights will blink.
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 062155
(included with the operator) 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:
• Delete all remote controls and reprogram.
• Make sure remote push button is not stuck "on".
• Disconnect all push buttons or key switches attached and
wait one day.
9. Door stops but doesn't close completely:
Review Limit
Adjustment section.
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 Safety Infrared Reversing Sensor (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.
11. Opener light does not turn on:
Replace light bulb (40 Watts maximum). Replace burned out
bulbs with rough service light bulbs.
12. Opener light does not turn off:
There may be a defective earth at the ceiling or wall
receptacle. The unit must be earthed.
13. Opener strains or reversed during opening:
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 change force settings.
14. 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.
15. 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 (if fitted) disconnects
the trolley from outside the garage in case of power failure.
