Endurance ProUniversal Bathroom Exhaust Vent Fan Motor Complete Kit Replacement for Broan Nutone C01575, 50 CFM, 120V Uppco, Ventorola E498-1 Bay Motors, Sears 569 Dayton, YJF6158 65100 EM550 (2 pcs)

I assumed a had a builder grade NuTone in my 20 year old house. It was buzzing, and would have liked to upgrade to a larger CFM and quieter fan. When I saw how small the box in the ceiling is, I just decided to replace the motor and not deal with attic and tearing the old box out. When I got the fan motor out, I noticed it is a BERKO Marley Qmark A664ICX2 motor. I guess that is a contractor-only model because I could not find much information on it. This motor and fan blade looked the same as the one I took out, so I decided to give it a go. It does match very well, and was an easy replacement. The fan shaft with the new motor was about 1/4" longer. It has a grove on the new one which made for and easy cutting guide, and I did cut that 1/4" off with a hack saw. I also noticed that the long thin bolts in the new motor that hold it all together are about 1/8" shorter, so I took the bolts off of my old motor to make mounting the motor easier. The fan works perfectly. It is quieter because I don't have the annoying buzz, but I guess it is as loud as the original motor was when it was new. It's good for now, but I do hope to swap it out for a stronger, quieter, more current technology in the near future. I included the name BERKO Marley Qmark A664ICX2 in this post to help find the replacement motor based on those keywords! :)

I have a 40 year old house with 40 year old bath fans. One of them was labeled "Air-o-matic" with a model number 605. It had gotten horrendously scratchy and loud over the years, to the point that it was a little scary because it wasn't clear to me what could even be making the noises it was making. This fan motor is obviously out of production, and the fan assembly/housing itself is totally different from any of the modern ones I've seen, so buying a whole fan kit and just replacing the inner part wouldn't work. (For newer fans that need replacing, you don't even need to unscrew the old motor. You can just clip in the new motor and bracket, since fan housings now are basically standard.) I had almost resigned myself to replacing the entire housing, which is a big pain in the butt if you're not an electrician or handyman.But then I found this. I actually found a slightly different model somewhere else that another reviewer had mentioned worked as a replacement for his Air-o-matic, but I realized pretty quickly that all of these replacement motors look more or less the same, and have basically the same shape as my Air-o-matic. I also realized that my fan mounting bracket actually has one screw hole that's elongated to give a little leeway for mounting replacement motors with slightly different screw placement, so I just took a chance on this.I had read that I needed to convert this from CCW to CW, which made me a little nervous, but it was very easy to unscrew the two pieces from the top and just swap them around - that's all it takes. Then I just screwed it into my existing mounting bracket, plugged it in and boom - working fan! I tested the airflow with a piece of tissue paper just to make sure it was blowing out with the orientation I set, and it was.It turned out to be very easy to install, and it sounds like a new fan (because it is). It's maybe not the *best* motor, and it's definitely not silent, but that's ok because I don't want silence when I'm doing my business in the bathroom. I like to know the fan is on and I want other people to hear it too. So there is some normal fan noise, which is good, and there's also just a tinge of low-frequency motor noise or vibration. My other bath fan, which seems like a replacement already (I am not the original owner of the house) has this same sound so I think it's normal. It's barely noticeable and I probably only even hear it because the whole point of me doing this was to fix a noisy fan, so I'm listening for it. In any case, it's a massive improvement over what was there before.One thing is that this is a 50cfm fan - and most of the "universal" fans and motors I've seen are. It's perfectly fine for small bathrooms but I'll bet there are even some larger bathrooms out there that this would not be enough for. Most computer case fans move significantly more air than that. (In fact, not really sure why we don't just use those fans for bathrooms - they're smaller, cheaper, and easy to replace.) It definitely would not be enough for something like a garage, unless you have more than one.In my case, though, I'm using this in a bathroom that's about 4x10. It's plenty enough for that. I realized after installing it that my old fan wasn't really doing much at all; I would get steamed up mirrors when taking a shower and would have to almost immediately open the bathroom door to keep from having that "sticky" post-shower feeling (where you feel like you need a shower right after taking one), even with the fan on. Not any longer. My bathroom is totally dry after taking a shower now.Hopefully this is helpful to someone out there with an old fan you don't know how to replace. Take the vent cover off and look at your fan motor. If it looks at all similar to this, you can probably replace it with this motor. Unplug your fan and unscrew the mounting bracket and look at the shaft length and fan diameter as well. You can take some exact measurements but I just took a chance. You can always cut the shaft if you need to as well. For me, the whole thing was just a drop-in replacement once I changed the orientation.

Fit perfectly and works great, so much easier than getting a whole new unit

Good product

The motor is completely universal as described and easy to install. I have the original bathroom exhaust fan built 1987. The original fan motor is shot and due for replacement. The original fan box is mounted inside a wooden frame/box which make it a challenge to remove. Replacing the fan motor is much easier, save time and cost less then replacing the entire exhaust fan with box. The motor came equipped with the fan included and design to mount on top of the mounting plate. For my installation, I had to disassemble the motor to reverse the motor shaft so that the motor can me mounted below the plate with the shaft going through the plate (as seen in the pictures). This allow the motor spinning/moving in the right direction. Overall took about 15 min or more to install. My only complaint is the plug that came with the motor is polarized, so it wouldn't fit into a non-polarized outlet. This is not necessary because the motor spins only one direction no matter what polarity (positive or negative) you use. Anyway, I had to modify the prong to the plug so it fully inserts into the outlet and trim a little around the outer rim of the plug to help push the plug all the way in. Other than that, the installation is a piece of cake. I suggest anyone who looking to replace the bathroom exhaust fan motor to remove the original fan motor first and take measurements to make sure it fits before you order online.

Was worried it would be difficult to replace, or that it wouldn't fit somehow. But installation was very easy, and it's so incredibly quiet. The contractor that installed our fan had broken one of the blades on the old fan, so the fan didn't last a year before it starting making awful noises and acting off balance. This new fan has made all the difference in being almost silent. Air flow is great as well. Ended up using the screws from the old fan to mount the new fan

My house was built in 1991 and the exhaust fan motor quit working. This fit perfectly and I was able to just replace the old Broan motor instead of replacing the whole exhaust assembly. Go to u-tube to watch how to take out the old motor. It's very easy to do and will save you quite a bit of money over buying a whole new exhaust fan assembly.

Easy to replace and still running well after a year!

My bathroom fan motor died suddenly. I was bit skeptical about buying a replacement motor kit online, wasn't sure if it would fit and work just the same as the one the builder installed in my home. I read the reviews on Amazon and decided to go ahead. I was pleasantly surprised. Fit perfectly and I can't tell the difference between this one and the original one. I hope it lasts years as did the original, let's wait and see.

Exelente cumple al 100

This motor is the perfect solution for replacing an old broken down motor from an ancient bathroom fan model. Its basically plug and play. My old motors collected too much dust so over time they deteriorated. This is a much better option than buying a whole fan unit, especially if you don't want to take down the old unit.Its a little bit more expensive, but it saves a lot of hassle.

Works perfectly. Easily installed

Mount spacing was as expected. Shaft diameter smaller than hoped for but fan included with motor did the job once the rotation direction was reversed. No instructions, but figured reversing meant removing armature and flipping it around 180 degrees. Past experience with electric motors raised fears that there'd be brushes and springs all over the place. Fortunately this did not happen and the armature reversed easily to drive fan in right direction. Unit is quieter than fan it replaced and works well so far.
