HAVING A PROBLEM?
(TROUBLESHOOTING)
1. 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 7.
•
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 (see page 3 for reference).
2. Opener operates from the remote, but not from the
Door Control:
•
Is the door control lit? If not, reverse the wires. If the
opener runs, check for a faulty wire connection at the
control console, a short under the staples, or a broken
wire.
•
Are the wiring connections correct? Review
Installation
Step 5,
page 10.
3. The door operates from the Door Control, but not
from the remote control:
•
Is the door push bar flashing? If so, Lock mode is
engaged. Make sure it is off by pressing the
Lock button for two seconds.
•
Program the opener to match the remote control code.
(Refer to instructions on the motor unit panel.) Repeat
with all Remote.
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.
5. 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 control
console and the motor unit.
•
Clear memory and re-program all remote controls.
6. The door doesn't open completely:
•
Check power door lock.
•
Is something obstructing the door? Is it out of balance,
or are the springs broken? Remove the obstruction or
repair the door.
7. The door opens but won't close:
•
Check cable tension monitor (see
Installation Step 4
).
•
If the opener lights blink, check the safety reversing
sensor. See
Installation Step 9.
•
If the opener lights don’t blink and it is a new
installation. See
Adjustment Step 2
. For an existing
installation, see below.
Repeat the safety reverse test after the adjustment
is complete.
8.
The door reverses for no apparent reason and
opener lights don’t blink:
•
Check cable tension monitor (see
Installation Step 4
).
•
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
.
Repeat safety reverse test after adjustments.
