Nutone QT100 and QT100LH
Bathroom Fan Replacement Parts
If your unit is
broken, there are only two options: replace the broken components or completely
replace the unit with a newer production. Each of these options has its
benefits and drawbacks. The most difficult part in replacing parts is knowing
which ones need to be replaced. The most common part to fail in a QT100 and
QT100LH is the S86322000 Motor. However, replacing the motor isn’t as simple as it
appears. The motor needs to be removed from the bracket and the wheel needs to
be properly balanced; balancing the wheel correctly should only be performed by
a trained technician. If the wheel is not properly balanced, it could cause the
wheel to rotate unevenly and cause the motor to fail because of the rotational
stress. To avoid assembly and balancing complications, many technicians
purchase the S0696B000 power unit assembly. This is a ready-to-install assembly
that does not require any alterations; simply remove the old assembly and
install the new one.
The alternative option to replacing broken parts is to
completely remove the entire existing unit and replace it with a new
production. However, this process could be more difficult than replacing a
part. In order to replace a unit with a different one, you need to know the
exact dimension of the fan cutout, the dimensions of the cover, and the
appropriate amount of CFM to adequately exchange the air in the bathroom. The
most difficult task is finding a new bathroom fan that fits in the same cutout
as the old fan. A large majority of new production fans are often smaller in
size, so the existing cutout is too large. It is also important to know that
the existing housing for the old fan is not universal and will not work for
other units; it will need to be removed.
After you have removed the existing housing and found a new unit to take
its place, it is recommended that a qualified technician installs the new fan.
The installation process involves some difficult steps, such as mounting,
disconnecting power to the old unit, and reapplying it to the new one.
