Garage door opener parts
Save cash - replace only the parts
getting it right the first time
Each of the many
involved a garage door opener installation has it's job to do.
The main part that makes it all work is the motor - without
that the door would have to be opened manually. These motors
generally do not have to be very powerful since a properly
installed and maintained garage door should be well
counterbalanced with springs. The motor has relatively little
heavy lifting to do.
Some of the parts that are needed
for a garage door opener to run smoothly must be fitted when
the door is installed as part of the process. Although they can
be retrofitted to existing doors in most circumstances, an
installation that includes both a door, an opener, and all its
parts usually results in the smoothest operating assembly.
One big reason why all the parts
benefit from being installed at the same time, is the balance
issues discussed above. This makes the pairing of the garage
door opener with the door and spring important part if the
The garage door opener drive system
can be belt driven, screw driven or chain driven and these
days, the belt drive unit is the most popular due to the
quietness of operation.
The chain driven openers are often
used for heavy double doors, made from heavy steel sections
that are too heavy for a belt drive. They are also less
expensive than belt drives but noisier. Screw drives are not
often used any more, but they are useful if a door is solid and
very heavy since screw drive style units can pull a lot of
leverage compared to the other drives.
In either type of garage door
opener, one common integral part of the machine is the trolley
- it runs along the track and is attached to the top of the
door. Apart from the screws and fixings, and various lighting
options, there is nothing else involved apart from the door
parts and the controllers.
One final opener part worth mention
is the remote control. This is a pretty important part of the
entire assembly. The best controllers generate a new code every
time the door is opened. This maintains security against
anybody electronically sniffing the codes and gaining
unauthorized access to your garage.
The garage door opener parts are
mostly the same no matter what model of opener you purchase.
They differ in design and quality, but function wise, they
don't differ much. Whatever you choose, unless you have been
well trained, you are advised to have your garage door opener
fitted by a professional.
