S99080166 BP28 Bathroom Vent Bath Fan Motor Kit Replacement

The Verdict

Your bathroom fan starts humming like a trapped bee, then stops spinning entirely. You pull the cover off, and the motor is seized. You’ve got two options: call an electrician (that’s a $150 trip minimum) or spend 20 minutes and $19 replacing the motor yourself. The Fetechmate S99080166 BP28 kit makes that second option genuinely painless — for most people.

This is a direct replacement for the Broan/NuTone BP28 motor assembly, which lives inside a massive number of builder-grade bathroom fans across North America. If your fan housing has a label reading “BP28” or your fan is a Broan/NuTone model from the last 20 years, there’s a strong chance this fits. The kit includes the motor, the blower wheel (squirrel cage), and the mounting bracket — everything you need except a screwdriver.

What you actually get

The package is refreshingly complete. You get the motor with the blower wheel already pressed onto the shaft, a mounting bracket with the correct hole spacing, and a pre-wired connector that plugs directly into your existing fan housing. The motor is a 120V, 60Hz unit — standard North American residential spec. The blower wheel is the same 4-blade squirrel cage design as the OEM, so airflow characteristics should match the original.

Installation is straightforward if you’ve done any basic DIY. Unplug the old motor from the housing connector, remove three screws holding the bracket, slide the assembly out, and reverse the process. Most homeowners report 15–30 minutes start to finish. One verified buyer put it simply: “Dropped right in. Took longer to clean the dust out of the housing than to swap the motor.”

What buyers consistently praise

The dominant theme in the 225 ratings (4.5 stars) is that this is a perfect fit — not a “close enough” fit. Multiple reviewers mention matching the OEM part number exactly, and several note that the motor is actually quieter than the original. One reviewer wrote: “I was expecting it to be loud and cheap. It’s actually smoother and quieter than the original motor was when it was new.”

Another common praise point: the price. At $18.99, this runs about half what you’d pay for the Broan-branded equivalent at a big-box hardware store. For a part that typically lasts 10–15 years, that’s a solid value proposition.

Where it falls short

The honest downsides are worth knowing before you buy. First, the pre-wired connector pigtail is short — maybe 6 inches. If your fan housing has the junction box positioned awkwardly, you may struggle to plug it in without contorting your hand. It’s workable, but not ideal.

Second, there’s no real instruction manual. You get a basic exploded diagram, but if you’re not comfortable with small appliance wiring, you’ll want to watch a YouTube video first. The wiring itself is a simple plug-and-play connector — no wire nuts required — but knowing which screws to remove helps.

Third, this is a motor kit, not a full fan assembly. If your housing itself is cracked, rusted, or the damper is failing, this won’t fix that. You need a working housing for this to solve your problem.

Who should buy this

• The DIY homeowner whose fan is making noise or not spinning. If you can use a screwdriver and unplug a connector, you can handle this.
• Landlords or property managers maintaining multiple units with Broan/NuTone fans — keeping a spare on hand is cheap insurance.
• Anyone quoted over $100 for a fan motor repair. This kit is under $20 and takes less time than waiting for the service appointment.

Skip it if your fan housing is damaged, you need a whole new fan unit, or you’re not comfortable working near electrical connections — though the connector design minimizes that risk.

FAQ

Q: Will this fit my Broan/NuTone fan? Check the label inside your fan housing. If it says BP28, or your fan is a model like 763RL, 671, or similar Broan/NuTone units using the BP28 motor, this fits. Measure the housing opening if unsure — the mounting bracket is roughly 8 inches across.

Q: Is the motor quiet? Yes, generally. Multiple buyers report it runs quieter than the original OEM unit. It’s not whisper-silent — it’s a bathroom fan — but it won’t rattle or hum obnoxiously.

Q: Do I need to rewire anything? No. The kit uses a plug-in connector that matches the housing. You unplug the old motor and plug in the new one. No wire nuts, no electrical tape.

The Verdict: 4.6/5

Buy it if you have a BP28-based Broan/NuTone fan and a basic screwdriver. This is the cheapest, fastest fix for a squealing or dead bathroom fan, and it’s genuinely a drop-in replacement.

Skip it if your housing is damaged, you want a heavier-duty commercial-grade motor, or you’d rather pay a pro for peace of mind.

For under $20, this kit solves a problem that would otherwise cost you a service call. That’s a win in any homeowner’s book.
