Question: I have a dead NuTone bath exhaust fan.  Age unknown.  The number on the unit is ( C-350C2N B UNIT ).  Is your C350BH assembly what I need?
Document: I ordered this to replace a unit that was broken. It was a direct replacement. One screw and plugged it in. Worked great. Much easier than replacing the entire unit.
Purchased this motor as an exact replacement for a 20 yr old bath fan. An easy install with just one screw and clip. Wiring just plugged in.
Took a little research to find the right fan to replace the twenty year old one in our bathroom. This unit plugged right in and works fine. Good price on Amazon.
It was everything as advertised. Arrived quickly. Installed quickly. Providing great service. I would recommend it too anybody who needs a replacement.
.....very easy to replace noisy , rusty old fan motors + blades....find the model # look it up, order it, put it in......parts for most older models still available...simple to install.......aahhh quiet.......git er done.....
The price isn't too bad, it's an OEM replacement part, reasonably price and it showed up quickly. Not much else to say.
Answer: no
