Universal 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 (1 pc)

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.

I have now bought this twice, for two different homes, and continue to have high praise. Most recent install below. 1) I bought this fan again, after initial great success, to replace a ~30 year old Broan fan with a different mounting system than this fan has by default. As another poster shared, the mounting screws are REVERSIBLE on this fan, which I did reverse to install fan in a similar configuration as existing fan, with the motor now mounted up into the ceiling, as opposed to default configuration to mount fan down into a corresponding bracket (which my second install didn’t have . See pics. As other reviewer recommended, it may be easier to buy some 3" 6-32 bolts to make this connection a little longer when flipping the mounting bolts - mine just barely worked though. Highly recommended again! —————————— 2) ORIGINAL review This truly is a universal fan for one simple reason - the electric motor axle comes pre-scored to allow you to trim to size for your particular branded housing. I particularly bought this fan to replace a >40 year old Broan 660 series bath fan (664/665/666 fan- see housing pic). Despite having originally attempted to buy a Broan-branded fan, and despite Broan being very good about maintaining identical parts/sizing over many years - I could not find a fan that was labeled as matching my Broan series. I quickly discovered no one makes a Broan 660 series fan anymore, because the vintage Broan 660 series bracket is approximately 2 inches between the mounting hardware, versus the now-standard 1.87 inches centered between the mounting hardware. To make this work for my fan, I simply had to take a power drill and enlarge the mounting bracket holes to make this fan’s mounting hardware work. Given the vintage nature of my fan housing and some peculiarities to this Broan series, it took me a bit longer to swap fans than your normal modern switch out - between widening the bracket holes, cutting the electric motor axle to size, messing with the configuration of the mounting brackets (the fan housing bracket is supposed to go closest to the electric plug, as not depicted), the electric cord being slightly shorter than was used in the 1970s (requiring messing with mounting a few times until figuring it out), and figuring out the orientation of the fan to exhaust in my housing (the flat side of the fan should be facing you after-installed, as not depicted), I probably spent 2-3 hours total on just swapping the fan. All that being said, this buy saved me serious $$/time by not having to replace the entire housing in the attic, and this fan, along with a new Broan-branded grill, makes my setup brand new and ready for another 40 years. A few general notes for bath fan replacements - if you find insulation inside your fan housing, you likely have a more serious issue (your fan likely vents directly into the attic, or alternatively you have a hole in your exhaust line); if there are gaps between the drywall and the housing, tape it up to ensure all moisture goes through your new fan to be exhausted; and make sure you test that your fan actually exhausts (as opposed to installing it backwards by accident) by putting a piece of toilet paper up against the grill once you’re done.

When we bought this house the bathroom exhaust fans were already noisy and slow, but we tried to extend their life with lubrication, etc. However, the one in the master bath finally stopped working and would just groan, while lazily turning once every 10-30 seconds. I put off fixing it because I figured I'd have to replace the entire fan/light/heater unit and I wasn't finding many available that fit the existing opening, and I wasn't looking forward to doing the cutting/drywall/floating/painting/wiring/attic-climbing necessary to put in a new one. I finally bit the bullet and said, that's it, one way or another I'm going to fix this damn thing. I started from the bottom, meaning from inside our bathroom, to see what I could figure out about the unit without an attic visit (this fan is located up under the low part of the roof, getting to it in the attic would be a huge pain). I was able to figure out that the if I took off the light cover and removed the bulb, there was a retaining screw under there. When I moved the retaining screw I was able to remove the entire interior cover of the unit, after unplugging the easily unpluggable connector for the light fixture. That revealed the heater unit on one side (working fine) and the exhaust fan on the other side. The motor for the exhaust fan had an axle extending up into a metal box where the circular blades were, and the blades were a wider diameter than the opening, so I thought I might need to get in the attic anyway. But then I saw that the entire exhaust fan box was removable by taking out one retaining screw and sliding it to the side so that it released from catches. Once I got the exhaust fan box out the rest was straightforward. I detached the motor and went looking for something with the same specs. I found this one, which to my eyeball looked like an exact replacement. Thankfully, it was. When I got this replacement I reassembled everything, switched it on, and YAHOO we now have a working exhaust fan in our master bathroom. In retrospect this was an almost simple replacement, and I figure I'll be able to replace the fans in the other two identical units in about 5-10 minutes each, from the interior using a short stepladder. Attached are two photos. The first one shows a piece of bathroom tissue being held in place by the suction of the newly replaced exhaust fan (when I turned off the fan the tissue fell, fyi). The second shows a side-by-side comparison of the old and new fan motor units. This replacement motor is inexpensive, and I don't know how long it will last, but it appears to be manufactured almost exactly the same as the original fan, which lasted 24 years. Time will tell, and if I have any longevity issues with it I'll come back and update this review.

it functions, but im wishing it had more power. even for my small bathroom, it doesnt seem to clear the humidity out of the room quite fast enough. four stars because its cheap but works decently.

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! :)

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.

We have an old Nautilus N678-B fan that has, for the most part, hard to find parts. And replacing the entire fan unit will require more work in the ceiling than we want to do. In the past, we've replaced the fan by buying a whole fan assembly with a compatible fan, but this time I found this one first and it looked right to fit. And Broan bought Nautilus so figured it would probably be similar enough. And it fits perfectly, was easy to install (how could it not be?), and is quiet. Two points I had trouble, but neither is all that significant. First, the new fan did not come with locknuts. Frankly, it's weird to have a vibrating unit that doesn't. But I use the serrated nuts from the old fan, no big deal. Second, it has a polarized plug. And the socket in our old fixture isn't polarized. It's a bidirectional motor, which means polarization is irrelevant. There's no reason to have a polarized plug. The two options were to just jam it in there until the plastic deforms, or shave some off of the wider prong. And a dremel tool fixed that. A nice replacement fan, and even if it doesn't have the longevity of an OEM fan the low price more than makes up for it.

I’m giving 5 stars just because of how quiet it is. The install was pretty simple but I ran into a couple of issues. Issue 1. My motor and fan sat on a metal bracket that was held in place by 4 steel rivets. I had to drill out the rivets to remove the bracket with the old motor and then use blind rivets to reinstall the old bracket with the new motor. Issue 2. The old fan slid onto the motor shaft and was secured by a clip that went on the top end of the shaft. The new motor and fan came without a clip to secure the fan to the shaft. I tried using the old clip but it broke while attempting to remove it. I will say that the fit between the fan and shaft is very tight and I would be surprised if the fan ever slid back off. Issue 3. The shaft on the new motor is longer than my old motor and it was hitting on the top of the fan housing. I ended up cutting about 1/4 inch off of the shaft and that did the trick. I realize that this might be more work than some people would want to do but in my mind it was a whole lot easier than having to go into the attic to replace the entire unit. In fact, when I am done with this review I will be purchasing 2 more of these for my other two 18 year old fan motors.

Exelente cumple al 100

Very pleased with the quick delivery and quality of this product. This fan is a bit noisy, but that is a design issue with all fans of this type and style. It is an economical type, but does the job. Overall I am satisfied with this product.

Works perfectly. Easily installed

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.

This motor is of good quality, and has important dimensions given on the Amazon.ca webpage so I could judge if it fit my case. I used it to replace the motor of my Superior-Broan washroom exhaust fan, Cat No. 664, 0.5 Amp. This motor is rated 0.6 Amp so it runs a little faster and the reduction in noise level therefore is not that much. The plastic centrifugal fan blade that comes with it is too small, so I had to reuse my original metal fan blade. In order to use this motor, the major adjustments that I had made are: 1. Cut short the shaft of the motor a bit (at a marked grove on the shaft), using my Dremel tool. 2. Use a 3/16" drill to open up the hole on my existing metal fan blade so that it can fit the 3/16" shaft of the new motor. On second thought, probably step 1 is not required. The shaft length of the motor may be accommodated in my existing set up.
