Having a Problem?
I. The opener doesn't operate from either the 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
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 Door Control, but not from
the remote controh
• 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 motor unit 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 side or back panel of
motor unit extends fully downward.
• Some installations may have shorter range due to a metal
door, foil backed insulation, or metal garage siding.
(Antenna Extender Kit 41A3504)
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
41A3263 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 motor unit.
• 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 5 feet, the travel limits may need
to be increased. One turn equals 2 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 28.
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 lights blink, check the safety reversing sensor.
See Installation Step 10.
• If the opener lights don't blink and it is a new installation,
check the down force. See Adjustment Step 2, page 29.
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
lights don't blink:
• Is something obstructing the door? Pull the emergency
release handle. Operate the door manually. If it is unbalanced
or binding, call a trained door systems technician.
• Clear any ice or snow from the garage floor area where
the door closes.
• Review Adjustment Step 2 on page 29.
• 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
lights blink for 5 seconds after reversing:
• Check the safety reversing sensor. Remove any obstruction
or align the receiving eye. See Installation Step 10.
12. The opener lights don't turn on:
• Replace the light bulbs (75 watts maximum). Use a standard
neck garage door opener bulb if regular bulb burns out.
13. The opener lights don't turn off:
• Is the Light feature on? Turn it off.
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 trained door
systems technician. 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. If the chain was
removed and reinstalled, the motor may be out of phase.
Remove the chain; cycle the motor to the down position.
Observe the drive sprocket. When it turns in a clockwise
direction and stops in the down position, reinstall the chain.
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 32.
• The Emergency Key Release 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 one-inch board,
no adjustments are needed (see page 11).
