Great vid! The only notes I would add is that the piezo element manufacturers rate the elements for 3000 hours of useful life. So at 10 hours a day for a month, and with six or seven months of use a year- you get the picture. It's the big weak link in all of these type products and it's why they will fail. The second note is that you will need to know the exact operating frequency and peak-to-peak voltage amplitude from the driving circuit. Find someone with an oscilloscope if you don't have one. Piezo transducers by their nature are only efficient at one single frequency and they will overheat and burn out quickly if overdriven. (Never run one of these babies without water!) The other note is that some sellers list their products by the size of the outer silicone ring and others list the size of the transducer itself, so it's a good idea to make sure which dimension is being specified in the ad.

Why does a metal disc (piezo) vibrating go bad ?

[@TCoupe60]

The ceramic layer might develop fractures - just a guess...

[@MOAON_AABE]

@@TCoupe60 interesting, makes sense, thank you.

[@stwoodsus]

This was exactly what I wanted to find on KZbin. I had a different humidifier but I followed along and thought it would work for my humidifier. Of course it did and the link for the 20mm ultrasonic piezo (2 pack) worked for me. I took the humidifier apart replaced the piezo. NOTE - I did not solder any connections on the board, I just cut wires from the old piezo and soldered them to the new piezo wires. I used some shrink wrap tubing over the soldered join to leave no bare wires. Thanks again - Steve

Should have said but my humidifier was a Homedics Cool mist humidifier from Bed Bath and Beyond but here is a link to the same one on Amazon. amzn.to/2UV7fud

Thanks for the video. My humidifier was a running weakly. I used your video to show me how to disassemble it. All I needed to do was to remove the rubber seal from around the membrane, clean the membrane, and re-assemble everything. Working great now.

[@Argblat]

Dustin, I want to thank you for making this video. I have very little experience working with electronics or soldering things together but I bought the replacement parts on Amazon and gave it a shot and I'm happy to say it was a big success. I'm only kicking myself that I didn't see this a few years ago as this is my second humidifier of the same model and I threw the last one out when this happened. Again, thank you, I'm really happy to have been able to fix this myself.

[@DustinRogersinMO]

Michael Montecuollo fantastic. I’m glad you decided to give it a try and even more delighted that your fix was successful. My thought is always “it’s already broken, what do I have to lose?” Thanks for watching and keep looking for things to fix.

Hello Dustin, Thank you for taking the time to make and post this video. My humidifier just stopped producing mist. Now that I see it is not that difficult, I will try to fix it.

[@jerriegall]

Thank you! This was so perfect. I had the exact one and it quit after a month and I was so grateful to come across your video and throw well your tutorial was. I’ve never soldered in my life and I went and taught myself that, ordered the mister and had it fixed in 10 mins start to finish. Thank you so much!

Great video and great job. I’m going to go try this on mine now. Thank you!

[@MikeJones-rk1un]

Good job. I have a different brand but found the same thing, same part size and all. Mine only lasted one winter but since the season is over now, I ordered a five pack from china for a lot less so I may have enough to last five seasons. Also I don't want to mess with soldering that printed circuit board so I'll just use butt connectors to wire it. Nice to see yours work tho. Thanks.

[@GrigorisDeoudis]

Thanks for this video. I have 3 x Medisana ultrasonic humidifiers for my plants, and paid €64 x 3. Two of them stopped working after 4 months of continuous operation during the day and the third one now is almost stopped misting. I guess I have to follow your steps and dust off my skills with soldering new piezo discs.

Exact same model here. I stupidly left mine on overnight after it stopped making mist and now the green light won’t come on at all. I feel dumb. We only bought it in February of this year, and it sat unused all summer. Edit/Update: going to take apart and see if I can find a fuse anywhere. Hopefully if that’s all that went for the power then I’ll be able to replace it followed by the piezo. Great vid, thanks for this kind of content!

[@davesmith5270]

You show de-soldering on the circuit board. On my model of "Air Innovations" I couldn't get the circuit board unfastened and feared doing damage by trying to remove the screws. I just cut the wires and soldered them together, using small heat shrink tubing to cover the joints. I had to buy a bag of 5 piezos online for 20 bucks, couldn't get just one. But 20 dollars vs. 90 for a new humidifier is a good deal.

[@WickedCrispy]

We bought a taotronics mister about a week or two ago and yesterday I observe it only seemed to be working at "half mist" power. The disc works but it doesn't seem to be making as much mist as it should. After watching your video I now have an idea of what to replace if it comes to that. I'm going to try cleaning mineral buildup around the disc and rubber ring first. Thanks very much for your video.

[@DustinRogersinMO]

Hopefully you can get it cleaned up and get some more life from it, if not, it’s a pretty easy repair.

[@WickedCrispy]

@@DustinRogersinMO Well, the new piezo discs showed up and I swapped a new on in. Issue persists, which leads me to believe it's something on the controller boards. I took it apart again and fiddled with the plastic wire jumper connectors. I flipped it over and it seems to be misting again the way it was. So, I guess one of those connectors is loose.

[@carlamarcantel91]

gee...I appreciate this easy to follow video and explanation. I'm anxious to attempt to repair my humidifier. I like it but was disappointed that it quit "misting" after the first year. I was ready to toss it when I found your video. You make this look SO easy. Wish me luck!

Audacity Of The Mind you’ll need to remove the original piezo disc and measure the diameter of it. I posted some links in the description to the common sized versions.

[@ahliahomes9002]

Hi Dustin. Thanks for sharing. I have different brand but same concept and the water leaks. Which part that potentially i should check and fix. Thanks.

[@DustinRogersinMO]

Ahlia Homes it’s going to depend on where it’s leaking from. There’s a silicone rubber around the piezo disc that could be torn, causing water to leak past it. It could also have a crack in the tank or possibly where the tank pieces are glued together may be failing.

[@dbolton1534]

P.S. - i wont do the soldering - just cut the wire near the disk and use marettes (wire nuts)

Butt connectors are easy.

I tried this, following your instructions, but no luck. Is the new transducer bad? I have no way to test it. Is something wrong with the water-level sensor? Possible, but what can I do to verify it or subvert it? It looks like I'll just end up buying a new humidifier.

[@garyjeffersii6735]

Thanks for the video. Anyone replace the dial (voltage regulator, I believe) before? I can hear and see my piezo working, but the dial doesn't affect output.

[@DustinRogersinMO]

Gary Jeffers II does the dial have two wires or three wires coming from it? If three wires, it’s most likely a potentiometer which are fairly easy to test. You may also try to google any markings on the dial component. You may be able to pinpoint exactly what kind of device it is and find a test procedure for it.

[@sygynri3735]

This is posted several yrs ago now but hopefully someone can answer... I first lost the floater the bottom part. I tried to replace it, not really the type it usually had and my humidifier still did not work. I tried buying the disk and replaced it but it still didn't create any mist. Now I am not sure if the disk is still the problem or the floater. Is the floater important? Coz I rmr before (when I first bought it)I turned on the humidifier and took the floaters(which I didn't know what it's purpose before) it produced mist. I tried looking if floaters are sold separately but I don't see any from all the ol shops I browsed.

Nice video. 20mm piezo comes in 2 different resonant frequencies. 1.7Mhz and 2.4Mhz. Circuit board has both frequencies marked where piezo connector is. Which one should I buy? Pureguardian brand humidifier.Thanks!

[@DustinRogersinMO]

Barrin Bonet I’m not sure I know enough about them to give a reliable answer. Does your board have separate contacts for each frequency? If so, I’d say order whichever piezo and just be sure to connect it to the appropriate contacts. If the same contacts are marked with both frequencies, maybe it doesn’t matter which you choose??

This one's footprint is a tad bigger but it still doesn't eat up a lot of desk space. Its size and shape blends into the background nicely. This has a good size water container so I don't need to refill more than once a week. I use filtered (not distilled) water because cleaning up after our hard water is tough at work. I like that this has several settings. It's also very quiet. (I have a silence naxi in the next cubicle.) It also hasn't left that terrible while powder, so far, that some humidifiers leave.
