1 Motor is making a Wha Wha Wha noise
The noise is definitely coming from the motor and the frequency of the wha wha noise increases with increased fan speed.
Is there a replacement motor available?

The motor bearings are shot. Here in the future (2025), it still appears to be impossible to get a replacement motor. (OEM item number ZWA138D58A) I assume this is due to Winix greed. Anyway, there are ways to replace the bearings if you're handy, but I've yet to open the motor casing so I'm not sure how easy they are to pull out. You'll need screwdrivers, a 10mm socket wrench (or equivalent), a soldering gun, a soldering wick, solder, and new bearings. I can't find anything definitive as to what type of bearings they are, but a post on Reddit states they are 608Z or 608ZZ bearings, like what's used for skateboard wheels. So if that's correct, at least they're cheap.
I assume Dennis has already replaced the unit by now, so I am just leaving this comment for anyone else who may be having the same issue. Good luck!

To Beth, and others in this thread: It appears that the 4 fans speeds on these Winix air cleaners were never calibrated properly by the final design approval
committee...meaning that the 4 speeds essentially are:
1. Ultra quiet (useless fan speed and air volume)
2. Very quiet ( just about as useless as fan speed #1)
3 Quiet ( moves a bit more air, but still pathetically too slow)
4. Turbo Hi-Speed ( Fan blower runs at what could be expected
to be the "Hi" speed setting, strong air flow volume)
Fan speed #4 is the only useful speed to operate the device, the others are all
way too slow with ridiculously low volumes of air being moved.
SO THEN... has anybody had one of these machines apart far enough into the guts of the interior to suss out if different rated resistors could be
soldered into the circuits of fan speeds 1,2 and 3 to make them all run
at a faster speed, and therefore move a greater volume of air??
Fans speeds 1,2 and 3 are all useless straight out of the box...
Thanks.
I also have this issue and it seems to be a motor starting to fail. Unfortunately I can't locate a replacement motor for a perfectly good unit. I, not thinking they wouldn't have replacement parts have left mine on high for a year to help with our extremely poor air quality with forest fires. 😢

@fisherofmen and Mike Stout have you checked to see if this is not a fan issue? Any build up of any "debris" on it? I am really sorry to hear about your forest fires....

Yes, I've completely disassembled the unit to the fan to clean it and check the fan for damage or unbalance.

Post an image of the compliance plate that is on the motor. Perhaps that may help to find a replacement.
Here's how 기존 질문에 이미지 추가하기 is done in ifixit
Also, if you haven't already done so, try and contact Winix and ask if replacements are even available

Mines doing the same thing, I tried getting some lithium into the bearings but I think they may be sealed as pushing it into the shaft space didn't seem to do anything
