Packard 40933 3.3 Inch Diameter Vent Fan Motor Direct Replacement For Nutone / Broan

I have Nutone exhaust fans model 8830 and I used this motor to replace the old 4135 motor that came with them in 1966. You have to cut off the shaft a little bit with a hack saw since its long and you need to turn around the 3 bolts to attach the motor to the old bracket that is in your Nutone fan (easy to do, just do them one at a time so that the motor doesn't fall apart if they're all out at once!!!) but other than that, it's a great replacement. Clears the air so much faster than the old dying motors. True they don't have oiling ports in them like the originals, but at this price if they fail in ten years or so, they can be replaced again and you can keep your rugged, metal squirrel cage (and metal grille and heavy metal chassis... Strong metal everywhere!) exhaust fan going good or better (these new motors have high rpm's) as new for years. Hardest part was getting the squirrel cage off the old motor. I auditioned this motor in one bathroom for a year and it has been so good I'm going to do the rest of the bathrooms with them now. Glad that this cheap Motor works great. No need to buy the super expensive "replacement" from the manufacturer. Chances are it's the same motor as this just marked up and with the sawed shaft and bolts turned around. Photo is "before". After is the same. New cord is ungrounded too, so it'll fit. Motor may need a little help to get spinning and be a tad noisy when you first use it, but after a few minutes, it'll be broken in and start on its own quietly

So far everythings great with the motor. We had an original Emerson pryne bathroom fan from the 60s or 70s. It became a potential fire hazard and really noisy after so many years. This motor was a direct replacement (and cheap) except that the housing is a bit wider/taller than the original which caused the fan to hit the top of the exhaust housing. For my application I was just able to add some washers as spacers to lower the motor a bit. It seems to do a really good job with the original metal fan blades (they don't make them out of metal anymore). It exhausts better than ever. I'm really happy so far - surprised I was able to find a mostly direct replacement for such an old unit. - EDIT - I realized my fan blade was actually CW I thought it was CCW. I flipped the stator as others have done and it works great now. Basically all you have to do is remove the two screws holding it together , cut out the power cord (I used a deemed), rotate the stator 180 degrees, cut a new hole for the power cord. Did that, put it back together, and it works great.

I thought I was going to have to improvise and get a "similar" motor, and just jiggy it to the bracket to make it work, but this turned out to be a direct replacement of my old motor (that was probably made in the '60s) The bolt posts fit my bracket exactly, and I had the fan working again in 5 minutes. The motor got quieter after running it a few minutes (probably to break-in the bearings or distribute the grease) ...and works well now.

This motor replaced an original model #M-684 Nutone bathroom fan motor (motor model # 1AAC077) that was installed about 60 years ago. Nutone no longer makes the original motor and no replacement for it is mentioned in any of the internet searches that I did. However, this one fits and runs perfectly. This motor, unlike the original, has a D-shaped shaft so the fan blower on the old unit, which did not have a D-shaped shaft opening, had to be replaced with a compatible D-shaped shaft fan blower. The vendor was prompt and on time in delivering the unit.

I used this motor to replace the one on an old nutone kitchen exhaust fan, probably from the 1960s or so. I didn't and still don't have a model number or any way to identify it specifically, but I included a picture of the inside grill in case anyone sees that they have a similar model, assuming they were sold as a unit back then. Since this is only the motor, the mounting bracket and fan blade had to be removed from the old motor and put onto this one. If anyone is replacing a similar model to the one I did, MAKE SURE YOU KEEP THE SPACERS. Without the spacers, you'll need to either find new ones or use the spare bolts to give the fan blade some distance from the outlet/plug or you'll risk damaging the power cord when you turn it on. This motor was designed for the housing that has an outlet along the duct to plug into. If your fan is previously hard wired (whether or not any of them are, I'm not sure), you'd either have to modify the cord on the motor or you'll have to rig up an outlet close by. Neither of which I recommend unless you really know what you're doing, but even then, there are other motors available for each specific usage, so DO THE RESEARCH, AND FIND THE EXACT MOTOR THAT FITS YOUR NEEDS. The fan I was working on used a pull-chain both as a switch and to open the exhaust door. I temporarily used a nylon shoelace while I wait for the replacement beaded chain to come in. Take note, that without a way to trigger the switch to both on/off positions, this fan will either stay running all the time or it wont run at all until you find a way to use the switch built into the housing of your fan, at least in cases like mine. For me, there's a small button that a metal bracket rests on, and the pull chain runs above it. When the button is pressed down (under tension from the pull-chain), the fan will turn off and stay off until the button is released. Then the fan runs freely as long as there is no tension holding the button down. If you're working on replacing a similar model, it would be wise to switch the breaker the fan is on OFF. If for whatever reason that isn't an option, or if you're just stubborn, make sure to keep the fan unplugged until after it's mounted. Once it is mounted and you're ready to plug it in, make sure the button is pressed down (either with the pull chain mechanism or otherwise) and get all your digits away from the blades. While I don't think the motor is strong enough to chop off your fingers, it would still definitely hurt a fair bit, so be careful. I wrote this long-winded review in hopes of helping any homeowner that may be inclined to make this replacement him/herself. If you can afford to, just hire somebody to do it. But I know everyone isn't in the financial position to pay for a job they could very easily do themselves. It isn't hard to do, just pay attention and be careful.

Bought along with Amazon suggested blower wheel. When I received it the says the motor has a 1/4 inch shaft. The blower wheel says it fits a 1/4 inch shaft but clearly doesn't fit on the motor. The hole on the blower wheel is too small and is actually cause a split in the wheel. This is ridiculous. Check your products to make sure everything is compatible as you claim cause it looks like this is going right back thanks for nothing

I was concerned at first as I wasn't sure if this would work. I purchased a few of these as my parents have a home that they built back in 1971 and the original fans were not working that well and one just flat out stopped working. My parents installed the old Air King fans for the bathrooms and I kinda liked the old Air Kings and felt they give a nostalgic feel to the bathrooms. It would have been a lot cheaper to install newer fans from the store in the bathrooms but I just liked the old look of the Air Kings so I went online looking for replacement motors and found the original OEM motors but they were running $141.00 online through some website and while I was searching for replacement motors I came across a blog that some guy had posted asking the same question as he couldn't find a affordable replacement motor. Another person responded to the blog and suggested this particular Packard motor as he has used it before for the same thing but needed some slight modification to make it work. I purchased them and that is what I did and I'm glad I did. The only thing is these Packard motors are around 1500 RPM where the original motor is 1800 RPM. Not a big significance and despite the RPM difference these Packards do the trick!

I am a professional installer. With this "Direct Replacement 3.3" Motor" we got a call from the building manager today that she smelled something burning in the restroom. We opened the vent fan and found the motor had locked up and melted the plastic fan blade. This is one motor of three, exactly alike, so I had to remove the motors from all three restrooms, rather than risk causing a fire in an Historic Theater. The manager and my company are very upset! They have a Grand Event this weekend, and their restrooms will be unpleasant, to put it nicely. I will lose hundreds of dollars in labor to find new replacements and pay my men to replace the motors. Who needs this kind of stress? And "AUTOMATIC OVERLOAD"??? The motor was burning! At what point was the "overload" protection supposed to kick in?
