In 2023, I replaced a motor in a fan like yours with a Mars Azure 10858. Ended up being way more energy efficient compared to BAF's original factory Genteq/GE motor and I was able to use a low power rotary switch for each of the 5 speeds since it had just a 24v input signal. I also used the Azure App to dial in the torque or RPM per speed tap for very low whisper quiet operation on the lowest tap. BAF's choice of motor for this fan was a bad idea. Should have done their research. If they did, they would have known the number of failures we here in the HVAC tech field have came across and replaced. At one point, we had a 50 gallon drum full of failed Genteq ECMs. A third of them had separated rotor magnets, some with shorted stator windings, dead shorts from blown high side module capacitors, the list goes on and on. If you replace the motor again down the road, consider the motor and model above. I'm almost through the 8th summer on a Sears & Roebucks Homart (formerly belt driven) fan using the 10860 Azure.
Thanks for this comment. I looked at using another ECM, but wasn't confident on how to control it. Most of them seem to use a 24v input signal to the tap wires. I guess that's because home thermostats use 24v signals to the unit? I wasn't sure how to accomplish this on the fan. Wouldn't I have needed a 24v power supply input to a 5 position switch with the outputs going to the motor taps, and then 120v going to the motor directly? I figured it was possible, but didn't want to spend the money on an ECM motor and power supply and not be able to figure out how to make it work.
@@Sockets_and_Sprockets I like the low voltage control and it looked like that box had enough room for a transformer. Wished I had seen your video earlier. I'd show you how to hook up. The Mars Azure motors have a slow ramp up time which I really like. It's not a whole bunch of air on you at once.
BLDC motors are seeing use in a lot of applications these days. You might be able to get a generic 3 phase ESC to that would drive that motor well enough.
I considered that when I was trying to decide what to do. What stopped me is it seemed like I would need to get an ac to dc converter and then a ESC, and I recall reading the operating voltage of the ECM motors is typically around 300Vdc. I couldn't seem to find a generic ESC that was advertised at voltage this high, and the converters were expensive and looked hard to package. But I still have the original motor, so I'm game to give something a shot if there is a good way to go about it. But when I was looking into it, this seemed more expensive and I had lower confidence in it working than going with the PSC.
Excellent video. My Yellow Jacket appears to have a controller issue as well. Very frustrating as it only lasted five years. I may have to do the same repair you did. Will you please share the part numbers for the motor and controller? Thanks
It looks like a nice fan, but I can't understand why it has to cost 3 grand. Does it move that much more air than any other 1/2 horsepower fan? You proved it will break just like anything else and cost a fortune to fix with parts only available from the manufacturer.
It does move a lot of air, but I think the real selling point in my mind is it's efficiency at lower speeds, and it's ability to move a relatively high volume of air at lower speeds (when it works!). So if you were going to run the fan around the clock in an industrial setting at low speed, that's probably the greatest value proposition in terms of energy savings vs a PSC motor driven fan.
@@Sockets_and_Sprockets $3000.00 is quite a bit of money. (to me anyway)I can just imagine me trying to convince my boss that it will pay for itself over years of continuous usage and then 2 weeks later hearing " We got that fan you wanted, only we found a cheaper one thats just as good." as they roll in a $150.00 fan from msc. Or scenario 2, they just laugh me all the way out into the parking lot.
I looked into that, but couldn't find anything that seemed well recommended. I tried soaking it in isopropyl alcohol, but that didn't help. Do you have any suggestions for what to use with a rubbery / silicone (I'm guessing) potting compound?

I seen that type of fan getting assembled on the channel called "how it's made"
Thanks for the video!
Can you share the motor part number?
Do you have the part for the motor and switch you used
Hi, Great videos.
Do you have part number for motor and switch?
the new motor looks like it's from a furnace blower
The new motor works great
Yep, it's a blower motor. Thanks for watching.
thanks for sharing man! good video!

Old motor loud you working motor new not loude
There are potting compound removal chemicals...

You would be better off order a new motor from Grainger
