So some history, I bought this fan from someone on Craigslist a few weeks ago. It was brand new in box never used. I set it up and it was working great. I did notice that it did not push as much air or move as fast as my Hunter Hotel Original but compared to my 2021 Matte Silver Original, it was very close. The fan was used for about a total of 3 hours maybe if that over the last 2 weeks. The other day I realized the fan was running slower than usual on low. I turned the fan off and tried high and realized it's barely spinning up. Now it's at a point where it just hums and hardly moves even on high. Switching between high, med, low causes the hum to go from loudest>louder>loud so maybe the capacitor is still working? I've attached a video to show what it's doing. The oil level was fine throughout the whole time I had it. I even removed the oil and put fresh oil in to see if it helps but it did not. youtu.be/vrZ-V0fTJpo

So far Dan told me to try the capacitor. I will see if I can test the capacitor today to see if it's bad.
eBay seller said it's the windings and wants $250 plus return shipping and for me to ship it so another round of shipping to fix it.
I know the capacitor can be tested to see if it's bad or not but how would I know if it's the windings?
I am assuming capacitor can be access by removing the lower metal plate and then removing the winding ring? Do I need to remove switch housing and strator as well?

See my similar post... yes about how to get to the capacitors, easy enough. FYI, the winding ring screws are kinda short and fall easily. The inner two screws hold a shield for the capacitors and wiring, try leaving those two for last as I think the shield is only attached to the ring and it should come down without removing them.

RobertM I have a multimeter with capacitance testing coming tomorrow so I will try to remove it tomorrow to see if the cap is bad. I think my model only has 1 capacitor. It sounds like you may have a newer model. Although our issues seem to have happened almost identically. Let me know if you get yours working again.

Well, how did you fare? Tested my caps with a fluke and then an analog meter using resistance (no cap test on either) and I didn’t trust the results. So I got a cheap pocket meter from Harbor Freight this morning and of course it was dead as a door nail. Went back and swapped it for another one and opened it in the store and tested the caps, both are fine. Now what? Any possibility it’s the reversing or speed switches? If it has to be the winding, I’ll buy a new DC Motor fan.

Decided if I’m testing it might as well try replacing it regardless and see what happens since it’ll be open. Capacitor coming saturday so hopefully by Sunday I’ll have an answer. One thing is for sure. Looking at this picture I took gives me some hope it might be the capacitor. If you can find some capacitors I would try swapping anyways or wait for my results. i.ibb.co/93dqRrB/F16-BFC14-22-D7-41-DF-A071-8-EAE0-D6-B2811.jpg

That does look like a blown cap, An AC one bulges the case so these would just leak like your photo. Got mine out easy enough, however look like new and test on Spec. Guess I’m buying a new fan. This one is the Chinese made (2010) so I guess I shouldn’t be surprised.

Dan told me a capacitor might look normal and even test fine sometimes and still be bad. If you can source your capacitors for cheap I’d give it a try. You can try asking the ebay seller I bought mine from. My 2012 Hunter Hotel Original uses the first generation overseas motor but it ran the best out of my 3 and is still running today *knocks on wood* I recently bought a 2021 Hunter Original Matte Silver which also performs well but that nor my usa 2a original keep up with my hotel original.

Yes about the removal. Once I got the blades off, and housing and ring, I removed the caps. They had a screw mount on the plastic cap housing and were attached to the upper cover with a short screw. Interesting about the various versions. I have a 2006 one still going strong. I'll take y'alls advice and get the caps. Btw who is "Dan". The only 4.0+7.5 cap I can find is from a guy who wants $25 for it and $25 for the 4.0. I can get a 4.0+6.0 or 4.0+8.0 but not sure which one is the right choice... I'm a mechanical not electrical engineer. I can of course get 3, 2-4.0 and 1-7.5 and wire tie the 3rd one to the upper housing cover. Kinda wish one of the 20 or so people would respond to my post.

Well, I thought I would check and see if there was a wiring diagram or something else available on the Hunter website. There wasn't, but via chat a Hunter agent said the capacitors had a 10 year warranty so those were not covered, so I figured I would get new caps and see if it fixed it. Hunter chat also said the fan Motor has a Lifetime Warranty and I still had available the recipt from Amazon, if the caps didn't fix it I should get a new one. I explained the whole situation and process via email with Hunter, buzzing, testing the caps, etc., and they said the buzzing is a bad motor and now they are sending me a new one! Great support from Hunter and there we go!

Great support from Hunter and there we go! Robert That’s awesome. My plan is to talk to hunter as well if the cap doesn’t work. I heard they will replace it with a new fan which would be an overseas motor but better than one not working. If mine works with the cap then I’ll stick to it since it is apparently a desirable motor.

Just wanted to provide an update. Replaced the capacitor and fan is working again! Old capacitor was reading 338 uF. New one is reading 7.55uF. The new one was a bit larger so I ended up putting it on the outside. Pic of old capacitor: Pic of new capacitor installed:

Old capacitor was reading 338 uF. Is it really 338uf or it's 0.338uf? I'm glad that the motor didn't get killed by that capacitor. The new one was a bit larger so I ended up putting it on the outside. Pic of old capacitor: Pic of new capacitor installed: Reminds me of when I replaced the capacitor on Versa•Touch 1B receiver for Casablanca S3 I got from Yale Peabody Museum of Natural History. I had to have the capacitor outside of the receiver, but it still fits in the motor housing so it still looks the same way as it was before when the top cover is installed. However when the capacitor was bad, it still looked fine, and high speed was about the same as medium speed, medium and low looked fine.

Nicely Done! My new fan is up and running nicely. But…. I’m having a hard time parting with the replaced fan. Oil is ok which I know b/c the other fan I haven’t oiled was only a little low. I may try to find a new motor
