Troubleshooting
1. The opener doesn't operate from either the optional
door control or the remote control:
• Does the opener have electric power? Plug a lamp into the
outlet. If it doesn't light, check the fuse box or the circuit
breaker. (Some outlets are controlled by a wall switch.)
•
Have you disabled all door locks? Review installation
instruction warnings on page 11.
•
Is there a build-up of ice or snow under the door? The door
may be frozen to the ground. Remove any restriction.
•
The garage door spring may be broken. Have it replaced.
•
Repeated operation may have tripped the overload protector
in the motor. Wait 15 minutes and try again.
2. Opener operates from the remote, but not from the
optional door control:
• Is the door control lit? If not, remove the bell wire from the
motor unit 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 the wiring connections correct? Review Installation
Step 6, page 18.
3. The door operates from the optional door control, but
not from the remote control:
• Is the door push button flashing? If your model has the Lock
feature, make sure it is off.
• Program the opener to match the remote control code.
(Refer to instructions on the opener panel.) Repeat with all
remotes.
4. The remote control has short range:
• Change the location of the remote control in your car.
• Check to be sure the antenna on the back panel of opener
extends fully downward.
• Some installations may have shorter range due to a metal
door, foil backed insulation, or metal garage siding.
• Is battery installed or weak? Replace battery.
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, the Vibration Isolator Kit
(62155) can be installed. This kit was designed to minimize
vibration to the house and is easy to install.
6. The garage door opens and closes by itself:
• Be sure that all remote control push buttons are off.
• Remove the bell wire from the door control terminals and
operate from the remote only. If this solves the problem, the
door control is faulty (replace), or there is an intermittent
short on the wire between the door control and the opener.
• Clear memory and re-program all remote controls.
7. The door doesn't open completely:
• Is something obstructing the door? Is it out of balance, or
are the springs broken? Remove the obstruction or repair
the door.
• If the door is in good working order but now doesn't open all
the way, increase the up force. See Adjustment Step 2.
• If the door opens at least 1.5m, the travel limits may need to
be increased. One turn equals 50mm inches of travel. See
Adjustment Step 1.
Repeat the safety reverse test after the adjustment is complete.
8. The door stops but doesn't close completely:
• Review the travel limits adjustment procedures on page 25.
Repeat the safety reverse test after any adjustment of door
arm length, close force or down limit.
9. The door opens but won't close:
• If the opener light blinks, check the safety reversing sensor.
• If the opener light doesn’t blink and it is a new installation,
check the down force. See Adjustment Step 2, page 26.
For an existing installation, see below.
Repeat the safety reverse test after the adjustment is complete.
10. The door reverses for no apparent reason and opener
light doesn’t blink:
• Is something obstructing the door? Pull the emergency
release handle. Operate the door manually. If it is
unbalanced or binding, call for professional B&D garage door
service.
• Clear any debris, ice or snow from the garage floor area
where the door closes.
• Review Adjustment Step 2 on page 26.
• If door reverses in the fully closed position, decrease the
travel limits (Adjustment Step 1).
Repeat safety reverse test after adjustments to force or travel
limits. The need for occasional adjustment of the force and limit
settings is normal. Weather conditions in particular can affect
door travel.
11. The door reverses for no apparent reason and opener
light blinks for 5 seconds after reversing:
• Check the safety reversing sensor. Remove any obstruction
or align the receiving eye.
12. The opener light doesn't turn on:
• Replace the light globe (40 watts maximum). Use a rough
service/heavy duty light globe if regular globe burns out.
13. The opener light doesn't turn off:
• Is the Light feature on? Turn it off.
• There may be a defective earth connection. The operator
must be properly earthed.
14. The opener strains or maximum force is needed to
operate door:
• The door may be out of balance or the springs may be
broken. Close the door and use the emergency release
handle to disconnect the trolley. Open and close the door
manually. A properly balanced door will stay in any point of
travel while being supported entirely by its springs. If it does
not, disconnect the opener and call a professional garage
door serviceman. Do not increase the force to operate the
opener.
15. The opener motor hums briefly, then won't work:
• The garage door springs may be broken. See above.
• If the problem occurs on the first operation of the opener,
door may be locked. Disable the door lock.
Repeat the safety reverse test after the adjustment is complete.
16. The opener won't operate due to power failure:
• Use the emergency release handle to disconnect the trolley.
The door can be opened and closed manually. When power
is restored, press the Door Control push button and trolley
will automatically reconnect (unless trolley is in lockout
position.) See page 29.
• The Emergency Access Device accessory (for use on
garages with no service door) disconnects the trolley from
outside the garage in case of power failure.
17. The chain droops or sags:
• It is normal for the chain to droop slightly in the closed door
position. Use the emergency release to disconnect the
trolley. If the chain returns to normal height when the trolley
is disengaged and the door reverses on a 40mm board, no
adjustments are needed (see page 11).
