Liftmaster garage door opener
The package included a Liftmaster
garage door opener - model 3280. That's a 1/2 horse
power machine and should be plenty of power for a door
that is installed and adjusted properly.
Earlier in this site I described how the old door didn't
close all the way, and the opener didn't have sufficient
strength to close the door without a counter weight bolted
inside the door. That old craftsman door opener was also 1/2
horse power, but there were so many problems with the garage
door adjustments that it was not powerful enough to close that
door without professional servicing. But with this new door,
properly installed and springs tensioned, it should be no
problem for a 1/2 horses power garage door opener getting the
This part of the job takes our installer some time. He has
to run all kids of wires to the remote control panel, and to
the obstruction sensors. The sensors and remote control panel
have to be mounted in the proper locations, wires run, and
connected all around.
The main 120v power supply to the opener was available just
as it was for the old machine. Power cord length was not an
issue, since the location of the new opener is about the same
as the old one.
After making all his measurements, our installer starts
attaching rails to the garage rafters that will hold the opener
in place. This kind of rail has bolt holes all along it's
length so getting the opener located in just the right position
With a framework of rails in place, our installer can mount
the opener and assemble the rest of its parts. The door is then
connected to the opener with a metal bar, and our installer
makes all the adjustments for open and closed stop positions
and lift and close strength.
The Liftmaster 3280 is a belt
driven unit and is very quiet. With everything
installed and adjusted it's operation is smooth and quiet.
It comes with two wireless remote controls for a two car
garage. The remote control panel mounted to the wall
inside the garage has a large button for operating the
door, a Light button and a Lock button.
The lock button is a security feature for use while you
might be out of town, and don't anticipate anyone needing to
using the wireless remote control to open the door. This is
used instead of a deadbolt.
The Liftmaster 3280 comes with two sockets for light bulbs.
Apparently no actual light bulbs are provided by either the
manufacturer - Liftmaster or the garage door installation
company. So I got gypped on the light bulbs, but I had some
spare 75w bulbs laying around that I went ahead and installed,
and tested the light button.

For security reasons, you should adjust the radio frequency
that your remotes communicate with the opener on. Otherwise
your homes security could be easily compromised. A detailed
