Having a Problem? (Continued)
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 (1.5 m), the travel
limits may need to be increased. One turn equals 2" (5
cm) 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.
