We have a NuTone range hood, and its two-speed fan is incredibly
noisy (10.5 sonnes at high speed, 8 at low speed), and we're trying
to figure out a cheap way to deal with the problem (cheap = not
replacing the entire unit).
The fan rocker switch has three wires coming into it, so we assume
the fan itself is limited to two speeds. Is this correct? Would that
preclude us from replacing the rocker switch with a rheostat?
Thanks in advance for any info.
If you slow it down enough to keep it quiet, why have it at all? It is
not going to move enough air to bother with if you get it that slow.
I would not just put a control on the motor. While you can get away
with that with some motors, I doubt if that builder's $9.95 special is one
The only real fix is to get a good quiet hood. I finally got one about
a year ago. It made a word of difference, it is not only quieter, by a lot,
but it also works better and looks better.
If it was a cheap fix, the factory would have done it. You have to change
the dynamics of the air flow both in the ducting and the blower wheel size
and blade configuration.. That is why the better hood cost much more.
I've seen heating/cooling units that were so quiet you could not hear them
run at all, but there were extremely expensive and usually larger than
competing units to move the same CFM.
