NuTone 8664RP Reviews

Rated 5 out of 5 by from Awesome Product I read all the reviews before purchasing this fan. Most of the complaints were about the noise level. This is a powerful fan so my own opinion is that the amount of noise that the fan puts out is very exceptable. The most important thing to me is that it gets rid of the moisture, it surely does a great job at that. The unit seems to be very well made. Instructions were easy to understand so Installation was fairly simple. I do most of my home repairs and upgrades but I'm certainly not a professional.

Rated 2 out of 5 by from Serves the requirement I previously had an older version of this fan in our shower, which has a tiled ceiling. The current version of the fan fit exactly into the opening I had to match in the ceiling, and the unit is operating as I expected The original fan motor was nosy; so is the new one.

Rated 5 out of 5 by from Fan The product looks good. It came with all necessary hardware and instructions. It is not installed you so i can comment on function.

Rated 2 out of 5 by from vibration intolerable I installed this ventilation fan/light myself, replacing one of the same specs which had gotten too old to just replace the fan motor. I can tolerate the 3.5 zone level but not the excessive vibration and metal-to-metal rattling of the new device. I will need to muffle this with some kind of rubber or cork sound insulation material. Old model did not need this. Old model was not made in China. (It was that old.)

Rated 3 out of 5 by from just average I had an electrician install the product wrong and the instructions were not much help. A you tube video was more informative.Dropping the glass lens to change a bulb or cleaning the lens is not easy.Spring clips that go up in the housing drop down to accomplish this. A screw in lens would be nice,and be sure to cut out the circular frame if you want it flush mounted to the ceiling.

Rated 5 out of 5 by from great buy Relatively quiet fan with great moisture removal capacity. We don't even see moisture on the mirrors at all anymore while using the shower and running the fan. How it lasts in the long term remains to be seen. However, for the money, I recommend this fan with 5 stars.

Rated 4 out of 5 by from Solid purchase Purchased this as a replacement fan. It is a bit noisy but very effective and we have enjoyed the purchase.

Rated 3 out of 5 by from NOISEY FAN This is by far a very nisy fan. IF this was to be used in a bath only I would return it. However, it is in a laundry room and noise is not a big factor.

8664RP would it happen to be the same model as 9092 from years ago. It looks the same. This one in this home would have been from years ago.........Thanks

The NuTone 8664RP is not the same model. The closest match would be the NuTone 9093WH.

Is the rough in can 9 X 9 square or 9" round?

The NuTone 8664RP housing is 9x9x6" deep. The grille has a 15" diameter.

Does the fan come with housing and mounting rails?

Yes, the NuTone 8664RP comes with everything needed for installation.

How do I properly remove the grill cover to replace the lightbulb?

Gently pull down on it to get it away from the ceiling then you can remove the spring clips to gain full access to the bulb.

I presently have an old model #8661--will the newer model fit in the existing space or will there need to be a lot of work done?

No, the NuTone 8664RP wont fit. You will need a new housing.

is the duct collar reverable - hose comes from the other side - other joist would require a 16 inch opening

The NuTone 8664RP duct collar is not reversible.

My fan motor has burned out. How can I replace it?

The best way to replace the fan motor for the NuTone 8664RP is to replace the Power Unit Assembly, Broan S97017706.


The NuTone 8664RP will only work with the suggested replacement parts. You can try calling Nutone directly to see if they can recommend a cover that will work. You can reach them at 888-336-6151.

can the duct collar be reversed to the opposite side - duct work comes from the opposite side

The NuTone 8664RP only exhausts from one side but to get the exhaust to come out a different side you can just rotates the housing so he exhaust side of the unit is in a place best suitable for your application.

Will this fan replace a Model 8663-m

Yes, the NuTone 8664RP will but the old housing needs to come out. It's the same diameter, however, the housing is different on the inside.

Can the light and fan operate independently, or when one turns on both turn on?

The NuTone 8664RP has a light and fan that can operate independently.

Is this considered Type IC (insulation contact)?

The NuTone 8664RP is Type IC for use with thermal insulation.

What is the difference between the 8663 and 8664?

The NuTone 8664RP does not have a night-light, which the 8663 does.

What are the model numbers for the grille and lens pieces?

The NuTone 8664RP replacement parts are s99111406 for the grille, and s61753000 for the lens.
