This should not be a problem. If you think you need a more powerful fan a there is a 110 CFM replacement fan that will fit in the same housing. The NuTone part# is 0696B000. There are some generic versions out there on ebay and amazon that have been causing people a lot of trouble. I would recommend buying from an Authorized NuTone dealer only.

Leviton triple switch
Nutone P66V

Nutone looks like an ordinary three-switch combo being marketed as a bathroom 'fan switch.'
The screws on the device would tell the story.

Look at the Leviton screws:
The switch has dark-colored screw on one side >> the hot from breaker always connects to dark screws.
Other side of switch has 3 silver-colored screws, but these can be brass colored screws > the wires to fan light and heater connect to each of these screws.

Most likely the Nutone switch is identical to the Leviton
I say this because the descriptor on Amazon describes it as a 'fan' switch.
It's being marketed as a bathroom fan-light combo switch >>> so it looks like an ordinary three-combo switch

Hi,

Here is a tip that I wrote about cleaning bathrooms fans that also addresses that issue at the end...

Hello,
The fan/motor part of the Broan fan is replaceable. They are actually very simple to take out and install a new part.

The part can be easily purchase here...

Does it start before the mark as you turn it if so replace the switch. power off first and check with a meter.

One drop of 30 wt oil at each bearing will quiet the thing for a while, but you will eventually want to replace it. Also consider the whole fan is about the same cost as the motor, and easier to find.

It is really easy to change the motor yourself. It is about a 15 minute job. You just need to find your model number and then you can buy the complete motor assembly. https://www.centralvacuumstores.com/model_number_help.php

I'm guessing that water isn't splashing up on this fan's motor, so the moisture that is causing the rust must be water vapor. The exact same water vapor that the fan is supposed to be removing. I have two suggestions before replacing the entire fan. One is to make sure that the ducting that carries the moist air out of the bathroom (and preferably out of the house altogether) is free of obstructions and that the fan can actually do it's job. Second is to actually run the fan, and run it a lot longer than you probably are right now. If it is running while you are in the shower and then you turn it off after you leave the bathroom, it can't possibly be removing that moisture. I'd invest in a countdown type timer and replace the existing switch with that. Set that thing for 30 or 60 minutes when you get in the shower and let it turn it off automatically.
