Having a Problem? (Continued)
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 (100 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.
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
bar and trolley will automatically reconnect (unless
trolley is in lockout position.) See page 24.
•
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.
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 flat, no adjustments are
needed. (See page 7.)
