Having a Problem? (continued)
Situation
Probable Case and Solution
The door won’t close:
1. Check the safety reversing sensor. If the sensor
lights do not glow, see page 23.
The door reverses
for no apparent
reason and the
opener light doesn’t
blink:
1. Is something obstructing the door? Pull the red manual release handle.
Operate the door manually. If is unbalanced or binding, call for
professional garage door service.
2. Clear any ice or snow from the garage floor area where the door closes.
3. Review the force adjustment procedures on page 29.
Repeat the safety reverse test after the adjustment is complete.
4. If door reverses in the fully closed position, decrease the travel limits
(page 28).
Repeat safety reverse test after the adjustment is complete. The
need for occasional adjustment of the force and limit settings is
normal. Weather conditions in particular can affect door travel.
The door reverses
for no apparent
reason and opener
light blinks for 5
seconds after
reversing:
1. Check the safety reversing sensor. Remove the obstruction or
align the receiving eye. See page 23.
...doesn’t turn on:
1. Replace the light bulb (75 watts maximum). Use a
“garage door opener bulb” if standard bulb burns out
prematurely due to vibration. Vibration may be
caused by loose end panel. Retighten the screws.
...doesn’t turn off:
1. There may be a defective ground at the ceiling or wall
receptacle. The unit must be grounded.
2. Is the Light Feature on? Turn it off.
The opener light:
The opener
strains or
maximum force is
needed to
operate door:
1. The door may be out of balance or the springs are
broken. Close the door and use the manual release
rope and 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 for a professional garage door
service. Do not increase the force to operate the
opener.
The opener motor
hums briefly, then
won’t work:
1. The garage door springs are broken. See above.
2. The trolley may be jammed into the stop bolts. Pull or push on the
door while the motor is humming to release the jammed condition.
Re-adjust the door limits (page 28) to prevent over-travel.
Repeat the safety reverse test after the adjustment is complete.
3. If the problem occurs
The opener won’t
operate due to
power failure:
1. Use the manual release rope and handle to
disconnect the trolley. The door can be
opened and closed manually. When the power
is restored, press the door control and trolley
will automatically reconnect (unless trolley is in
the lockout position. See page 32.)
2. The Outside Quick Release accessory (for use
on garages with no service door) disconnects
the trolley from outside the garage in case of
power failure.
The chain drops
to sags
1. 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
one-inch board (or a 2x4 laid flat), not
adjustments are needed. (See page 11.)
