What do the model numbers mean on Emerson fans?

[Tim Babcock]

Is there a photo or diagram of what the meaning of Emerson Fan model numbers mean?  Blade count, ect? Thanks

[Michael Bouthiller]

The first two numbers of a Emerson model number is the series number third number is cycles and the fourth number is how many blades it has and the fifth number is the diameter of each individual blade 

Hope this helps 🙂

you may need to poke around, but this website has an excellent Emerson product numbers and how the numbers mean a description 

I apologize for the poor grammar😉

I did a bit of poking, I tried messing with the washers. The only thing I found was that with the cap cover off the front, when I turn the fan on I can make it run by turning the rotor. but I can make it turn either way clock wise or counter clock wise. What would cause this?

The start winding may be open or the choke may be open or you may have it connected incorrectly.

I changed the wires from the coil with the  wire from the switch. I did not mess with the neutral. The coil looks great, but the head stater looks kind of messed up. The tape or what ever it is looks like old coffee grounds. I tried to clean it but it was like what ever it was the tape or something else is quite stuck. I don't want to mess up the windings. I do have another 3 wire head stater I could exchange. If anyone has the AB AC CB  diagram for this three wire head I would appreciate it.

I took the stater out and it seems to be the flying lead. Its DOA, no reading with any of the other wires. I have a three wire head stater that reads find on all three leads. I went by wire color instead of abc. Red, black, white. B-R 14.5 R-W 31.2 B-W 45.5.  I found this diagram on the site. Its for a 29646 then one for the 27646. the donor stater I had and don't know what model it came from. Its a three wire stater. The switch is for a three wire stater and came out of a 29648. Which diagram Would work this this switch?     I am guessing the 29646 would be the correct wiring diagram for this model. I am also guessing that the stater does not matter. That a 3 wire head is a 3 wire head. So by the ohms it reads Black to red =14.5, Red to White = 31.2, White to black reads 45.5.  So if I have deduced it correctly that would mean that White = A, Red = B and Black=C. Ao A-C should read 45.5, A-B 31.2 B-C 14.5. Hooking up to the first diagram should work. Did I calculate correctly?

Wire it like the first drawing. If that doesn't work, wire it like the second one. Note the drawing I made is not the same as the two that you posted.

Thanks Mark. Since your diagram does not have abc I made this diagram to give your drawing the ABC code.

So I got it all together and wired it like marks diagram. It runs good on all three speeds and the only issue is its running backwards. I know the stater is in right, I don't think its possible to get these in wrong.  So What would be the issue?

[Bob Peshoff]

Try switching the B and C wires.

[Mark Olson]

Put common on the choke flying lead

Put start to high on the switch

Put run to line

Arbitrarily re-naming start, run and common to some combination of A, B, and C only confuses me.

Thanks guys and mark that was the winning combo. Running good.

Tim, sorry you had so much difficulty in getting your fan to run correctly, but I do appreciate all the advice from all the AFCA members.  I know there systematic approach to solving your problem is going to help out a number of members, especially me.  Thank you all !

I realize this is an old thread….but WHERE in the site did you find this? The only diagrams I see are from John mcComa’s…some good stuff but there’s got to be more diagrams somewhere??????? Looking for a 21648…..I’m pretty sure it’s the same as the one you found (I have that one too and used it in testing this fan last week trying to determine if the switch was good…swapped a switch from a 19648). But just feel like I am Constantly not finding basic stuff that should be on the site somewhere. Thanks.

I did these diagrams many years ago to help me keep track of what is connected to what.  But this latest diagram I did was easier to understand.

Tom, do you have one for a 21648? I used the one in this thread and it seems correct. But just curious. Thanks btw for all your knowledge….gonna try to wind my firdt speed coil soon so I’ve been watching that video of you on the afca and trying to decoder as much as I can.

If you look at the instructions, you will see at the end where it refers to pre29646.  Just reverse 2 & 3.  

Winding the choke coils is not that difficult.  About 10+years ago, I built my choke coil winder from shop junk.  Contact me if you need any advice.

It would be super cool if you could put up a post about that. I imagine many would benefit from the tutorial and knowledge.

Thanks...
