Cylrod Upgrade 8664RP/8663RP Bathroom Fan Motor Review: Breathe Easier in Your Bathroom

Tired of a noisy, inefficient bathroom fan? The Cylrod Upgrade 8664RP/8663RP bathroom fan motor promises to be a cost-effective solution for restoring proper ventilation in your bathroom. This replacement motor is designed to fit a range of Nutone and Broan exhaust fan models, including the popular 6445RP, 671R, 672R, 8673RP, 763RL, and 769RL. If you're dealing with a struggling or completely dead fan motor, this upgrade could save you the expense of replacing the entire exhaust fan unit.

This motor boasts a 100 CFM (cubic feet per minute) airflow, which is a standard measurement for bathroom fan effectiveness. It also claims a relatively quiet operation at 3.5 sones. But does it live up to the hype? Let's dive into a detailed review to help you decide if the Cylrod 8664RP/8663RP is the right replacement for your bathroom exhaust fan needs.

Key Features of the Cylrod 8664RP/8663RP

Here are the key features that make the Cylrod 8664RP/8663RP bathroom fan motor a contender for your replacement needs:

  • Broad Compatibility: Designed as a direct replacement for Nutone 8664RP/8663RP B Unit and compatible with Nutone 6445RP, 671R, 672R, 8673RP, 763RL, 769RL, and 750 models.
  • 100 CFM Airflow: Efficiently removes moisture and odors from your bathroom, preventing mold and mildew growth.
  • 3.5 Sones Noise Level: Offers a balance between performance and quiet operation, reducing noise pollution in your bathroom.
  • Affordable Price Point: A budget-friendly alternative to replacing the entire exhaust fan assembly. Currently priced around $35.99, making it an attractive option.
  • Easy Installation: Designed for DIY installation, potentially saving you money on professional installation fees. Most users report a straightforward replacement process.

Pros: What We Liked About the Cylrod Upgrade

  • Excellent Value for Money: At around $35.99, this motor offers a significant cost saving compared to purchasing a new exhaust fan unit. This makes it an affordable option for homeowners on a budget.
  • Strong Airflow Performance: The 100 CFM rating ensures effective ventilation, quickly removing moisture and odors from the bathroom, similar to the original Nutone motor.
  • Relatively Quiet Operation: The 3.5 sones rating translates to a reasonably quiet fan, preventing excessive noise disruption during bathroom use. Many users reported it to be quieter than their old, failing motor.
  • Direct Replacement and Easy Installation: Designed as a direct fit for specified Nutone and Broan models, the motor is relatively easy to install with basic tools and some DIY knowledge. Many online reviews confirm a seamless installation process.
  • Extends the Life of Your Existing Fan Unit: Rather than discarding the entire exhaust fan assembly, this motor replacement allows you to keep your existing housing and fan cover, reducing waste and saving resources.

Cons: Potential Drawbacks to Consider

  • Noise Level May Vary: While rated at 3.5 sones, some users have reported that the motor can be slightly louder than expected, especially as it ages. This might be a concern for those particularly sensitive to noise.
  • Longevity Unknown: As a newer aftermarket product, the long-term durability and lifespan of the Cylrod motor are still unproven compared to original equipment manufacturer (OEM) parts. Some users have raised concerns about potential motor burnout after a relatively short period.
  • Compatibility Requires Careful Checking: It's crucial to double-check the compatibility of the Cylrod motor with your specific Nutone or Broan model number before purchasing. Incorrect fitment can lead to installation difficulties or performance issues.

Who Should Buy the Cylrod Upgrade 8664RP/8663RP?

The Cylrod Upgrade 8664RP/8663RP bathroom fan motor is an excellent choice for:

  • Budget-conscious homeowners: Who need a cost-effective solution to repair their existing bathroom exhaust fan.
  • DIY enthusiasts: Comfortable with basic electrical and mechanical repairs who want to avoid professional installation costs.
  • Individuals with compatible Nutone or Broan models: Seeking a direct replacement motor that offers good performance and ease of installation.
  • Those who are experiencing a failing or non-functional fan motor: But want to avoid replacing the entire exhaust fan unit unnecessarily.
If you are looking for a premium, ultra-quiet fan and willing to pay a higher price, consider looking at Panasonic WhisperGreen or similar high-end models. However, for those seeking an affordable and effective solution, the Cylrod is a strong contender.

Conclusion: A Budget-Friendly Fan Motor Worth Considering

The Cylrod Upgrade 8664RP/8663RP offers a compelling combination of affordability, performance, and ease of installation. While some users have noted potential concerns about noise level and long-term durability, the overall value proposition is strong, particularly for those seeking a budget-friendly replacement option for their Nutone or Broan bathroom fan. Just ensure you verify compatibility with your specific model number before purchasing.

Overall, it's a solid replacement option that can breathe new life into your existing bathroom fan without breaking the bank. If you are ready for a quieter, more effective bathroom experience, consider giving the Cylrod Upgrade 8664RP/8663RP a try.

Frequently Asked Questions (FAQ)

It works for now, but idk if I’d trust this for a high-traffic bathroom. It’s very lightweight. Installation was a breeze tho, took like 15 mins tops. It's a "get what you pay for" type of situation. hope it doesnt rust.

Omg, this stuff is so soft!! I used the 5lb bag to restuff two of my old pillows and they feel brand new but way more breathable than that foam stuff. It’s a bit pricey but tbh worth it if you want something that isn't full of chemicals.

The fitment on my 2022 S1000RR is decent but not 100% perfect. There’s a tiny gap near the top that bugs me if I look too close, but from five feet away you can’t tell. Its better than nothing for sure.

We recently remodeled our pantry using these 15-inch slides and the difference is night and day. They feel very sturdy even when the drawer is full of heavy canned goods.

I was skeptical because of the price point, but after a few rounds, the confidence boost is real. You can really see the correction on shots that would normally be way off-line. Just make sure you line them up right before you hit.
