My Buying Guides on Broan Nu-tone Motor Assembly For 8664rp And 8673

I found that focusing on exact compatibility made the biggest difference.
Why I Considered This Motor Assembly
I usually look at a replacement motor assembly when the original fan starts making unusual sounds, loses suction, or stops working completely. In my case, I wanted something that would bring the unit back to its original function rather than forcing me to replace the whole fixture. The Broan Nu-Tone motor assembly is appealing because it is designed specifically for the 8664RP and 8673 models, which gave me more confidence in the fit and performance.
What I Looked For Before Buying

- Ease of installation: I wanted a replacement that would not require major modifications.
My Buying Tips
From my experience, the best way to avoid disappointment is to compare the old motor assembly with the replacement part carefully. I always recommend checking the model number on the existing unit and confirming that the replacement is an exact match. I also suggest reviewing the product description closely for any included components, because some listings may only include the motor while others may include the full assembly.
Installation Considerations
I found that installation is much easier when the replacement assembly matches the original design. Still, I always make sure to:
- Turn off power before starting.
- Remove the old assembly carefully.

- Test the fan after installation to ensure smooth operation.
If I am not fully confident with electrical work, I prefer to ask a professional to handle it.

Instead of buying a whole new fan unit, I can often restore the existing one with a part made for the same model. I also like that a proper replacement can improve airflow and reduce strain on the system.
Things I Would Watch Out For
I always pay attention to a few possible issues:
- Some sellers may list similar parts that are not fully compatible.
- The assembly may not include every small mounting piece I need.
- Older fan housings may have wear that affects installation.
- Product images may not always show the exact version being sold.
My Final Thoughts
If I needed a Broan Nu-Tone Motor Assembly for 8664RP and 8673, I would focus first on exact compatibility and then on quality and installation ease.
