Having a Problem? (Continued)
10. The door reverses for no apparent reason and
operator 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 fl oor area where the door
closes.
•
Review
Adjustment Step 2.
•
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 operator
lights blink for 5 seconds after reversing:
•
Check the safety reversing sensor. Remove any
obstruction or align the receiving sensor. See
Installation
Step 10.
12. The operator lights don’t turn on:
•
Replace the light bulbs (75 watts maximum). Use a
standard neck garage door operator bulb if regular bulb
burns out.
13. The operator lights don’t turn off:
•
Is the Light feature on? Turn it off.
14. The operator 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 operator and call a trained door
systems technician.
Do not increase the force to operate
the operator.
15. The operator motor hums briefl y, then won’t work:
•
The door springs may be broken. See above.
•
If the problem occurs on the fi rst operation of the
operator, door may be locked. Disable the door lock.
Repeat the safety reverse test after the adjustment is complete.
16. The operator 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 bar
and trolley will automatically reconnect (unless trolley is in
lockout position). See page 25.
•
The Outside Quick Release accessory (for use on buildings
with no service door) disconnects the trolley from outside
the building 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 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 2x4 laid fl at, no adjustments are needed.
