ResMed CPAP Noise Solved

Got tired of waiting for a warranty response for my very noisy CPAP, so I disassembled my ResMed AirSense 10, blew the foreign particles out of the motor, reassembled the unit and now enjoy quiet nights of sleep. This video is only of the reassembly. Enjoy!

[@tcobbett]

I had a whining noise that seemed to vary when my mask was twisted, reducing airflow. I tried taking off the hose, reservoir and filter and holding a vacuum cleaner up to each hole and for now the problem is solved! Thanks for the advice!

[@nielbelmont551]

Thanks for the video. I had the same problem with noise. I just took mine apart and put it back together as you described. So far so good. Next time I will try the vacuum idea first though!

[@ExposeTheGenderCult]

My CPAP which is the exact same one just did this to me after about a year of using nightly. I turned it on it’s side and then back over and it stopped. At least now I know when it starts doing it again I can take it apart. It looked much more intimidating before I watched you

[@keithkirkwood6408]

My Airsense 10 started developed the whining noise at 6:15 this morning. I buried my head in the pillow until it was time to get up. My machine is a few years old and the screen reminds me every night that the motor has passed it's life. I thought, well I guess this is it! Over breakfast I found your video. Luckily I have a new AS10 that I use in the RV and when traveling. Swapping it out I looked at the air filter. I must say that I thought I had changed it recently, but by its appearance, I hadn't. (time to put calendar alerts on my phone!) With nothing to loose and thinking there has to be a lot of dirt in there, I opened up the filter and placed the vacuum over the intake port. There was a "whoosh" and something was sucked out. Thought to myself, well either that did it or that did it in. Plugged it in, hooked up may mask and it purred like the new one. Time will tell if this did the trick. I certainly would not have done it if I didn't have the new one in the RV. Moral of the story, change the filter regularly! (for which I had to order on Amazon).

[@MrMikedouthitt]

Thanks for the video! On mine I did notice I had some shorter and longer screws though. Airsense 10. The shorter screws are for the humidifier base. I accidentally tried using a longer one and it poked some stuff through

[@jwhan1979]

thank you! This saved me a trip to VA.

[@machigane7902]

Thank you so much to for taking the time to make this video. I had the same "whirring" sound when inhaling and/or holding my breath. I took apart the machine easily and your video was unbelievably helpful. It's thanks to content producers like you that consumers of content like me are able to fix things themselves and save $800 instead of buying a new machine!!!! I have a Resmed Autosense 10 so it's an APAP (I can set a range instead of just one pressure setting) and the only thing I'll add is that on my model the 4 screws that held the heating element plate were shorter than all the other screws. Not a big deal but not all the screws were the same in my case. Thank you again sir and I subbed to you as a thank you, which is the least that I can do.

[@ckstafford2003]

Had the same problem now it's fixed thank you kind sir.

[@Ben-bg2lp]

The background air flow noise is very fitting to the video.

[@jocelynbroughton5378]

Thanks!!! I have a Resmed 8. It started making a terrible noise. After viewing your video, I had confidence to take mine apart. No more noise!!!!!

[@jaritshyortega5606]

What did you do once inside?

[@bobk3993]

Great video. Helped me repair my machine. Bad motor in mine. Replaced it. Works like new.

[@jasonb4370]

The noise is also a bad seal,on the two sensors that are detecting the pressure on top of the unit. When you take the case apart. Receding or repairing and replacing those two seals make a big difference on how the noise of the motor. Machine is detecting a vibrating leak and is causing the motor to speed up and slow down very fast causing a wine.

[@EMTdrummer]

Quite a project to take on...thx

[@RicRab8]

Well, my CPAP started with the nose again, and knowing what worked last time ... instead of disassembling, I simply unplugged it, removed the air filter and the water reservoir, and vacuumed first from the filter port for 5 seconds, and then from the port on the reservoir side, again for 5 seconds. My CPAP operates silent as when new.

[@cebruthius]

I can see why you're having trouble all the time. You're using the CPAP wrecker known as the SoNotClean

[@johnphillips7950]

How's it been doing with the vacuum treatment

[@d.f.5528]

Hi Mr. Morris, I have the same model Cpap and I don't think I replaced my filter enough either. I waa wondering did you just use a regular vaccum cleaner to clean the ports?

[@JoeAroner-SIWAYTV]

@@cebruthius the SoClean only kills microbes, it’s not for dust, dirt, and hair.

[@cebruthius]

@@JoeAroner-SIWAYTV Ozone is only capable of penetrating outer layers of plaque. So the microbes below still live. Not that they do any harm (your face is full of microbes lol)

[@Smfmoneoonepointone]

I would like to have seen how you blew air through the motor and which end of the motor you sent the air through. Mine just got sent out for a warranty repair for that exact same problem.

[@jeffpurdy1392]

I had the same issue and this worked great. I have to believe that I waited too long to replace my filter and dirt got into the motor fins? Thanks for making this video..

[@Dankness9]

I think those filters are made to be kind of thin and seem inefficient for that much continuous air. I have the same problem now and hoping to try this out today.

[@TheDUTYFIRST]

Took mine apart 20 minutes ago and disinfected. Re-assembled. Still noisy. Think I need a new one!!

[@mackhucks2674]

Thank you sir! This gave me the initiative to do the same thing. I also used hot water with a microfiber cloth to clean it. I think using a soclean was part of my problem.

[@jamesblue13]

This video was very helpful! Thanks

[@ReunitingFamilies]

Yes, I'll add my thanks for making this video. It worked great!

[@wbwestful]

Any idea where you can get a replacement for the "C" shaped noise filter near the motor unit? Half of my noise filter disintegrated and looking for a replacement- no luck yet.

[@neptune1096]

I just used compressed air on the intake and output sides. My low end is set to 4 so I will need to wait and see once the pressure rises. I had been using the same filter and just wash and dry it. Could be the filter actually deteriorates with time and should change it more often. Live and learn. Thanks for the video.

[@smb2265]

neptune. When you say "i just used compressed air on the intake and output vents" did this fix the motor winding noises? Thanks for any help. Mine isn't covered since it's been only 3 years and I don't want to fork out $1000 for a new one. Cheers

[@neilbelcher]

Cheers mate. Worked a treat. Bonza.

[@lalocantu8830]

I disassemble the unit with electronic duster spray i blew the motor and walaaaa it works this is a helpful video

[@danielcazarezgarcia4827]

It makes noise only when expiratory pressure relief is off, does yours makes noise in both situations? (EPR OFF and EPR ON)

[@artoneartone9809]

So I blew out with dust spray compressed air the motor and cleaned my machine thoroughly. Put it all back together and that annoying whistle remains when I breathe into my machine. So it must be the motor whining because it's getting old and ready to die. Right?

[@JoeAroner-SIWAYTV]

Thanks for posting, it’s nice to have a reference while fixing things. My machine is over 7 years old, so I wasn’t too surprised to see build up of dust and dead microbes. I did do a couple of additional cleaning steps. I used some gum brushes and a small pick to clean each blade after using my Dyson V8 vacuum (with no attachment it fits nicely to the motor). Second, I used rubbing alcohol (isopropyl) to rinse the motor. I used about 1/4oz, just to get everything rinsed out. I then poured out the alcohol and vacuumed out the motor for 2 minutes to dry. Put everything back together and good for now.

[@alexzaritsky]

Really

[@JoeAroner-SIWAYTV]

@@alexzaritsky so far so good about a month and NO noise has come back.

[@shepatown]

Amazing! Thanks for the walkthrough. Mine does a wheezing sound too. I started looking for how-to fix it myself after getting the runaround because the 3yr warranty has ended. Does your CPAP still operate quieter now? I think that's what you said in the description.

[@ExposeTheGenderCult]

Yours has a 3 year warranty? I wonder if mine does too

[@shepatown]

@@ExposeTheGenderCult I ended up having to pay out of pocket for a new one, it made a similar noise within a month and I got it replaced by resmed. Tech said these models of a certain period are problematic. The new machine is working quiet so far.

[@RicRab8]

@@shepatown Did you have to pay for your replacement ResMed, or was it a warranty replacement?

[@shepatown]

​@@RicRab8 Yes, I had to pay for the replacement RESMED CPAP machine because the 3yr warranty had just ended. Apparently, my health plan will pay for a CPAP machine every 5 years. I still have the noisy RESMED machine that my health plan paid for that is no longer under warranty. I paid The CPAP Shop -online-for the replacement RESMED CPAP machine - then I had to return it because it started making that problematic wheezing mechanical sound and RESMED then replaced it. I didn't deal with RESMED directly - The CPAP Shop acted as the intermediary. (sorry for the long explanation)

[@RicRab8]

@@shepatown Thanks for your excellent reply. I'm guessing you did not or do not use the SoClean ozone cleaning device, true? ResMed is blaming the wheezing noise on SoClean, every chance they get.

[@hvydutytow]

So, I’m just finding out my whining resmed Airsense 10 has a filter… Am I supposed to replace it, now that I’ve used it for 2 years?

[@rocknhard11]

Where did you buy the part?

[@DavidBrown-gr8xh]

Do you have any videos of the original noise?

[@alanbourbeau24]

I have a cpap machine myself and sometimes when I use it at bedtime. Sometimes I hear a whining noise and I just don’t know what the cause of it is. It could be the mask itself or maybe I put in too much distilled water. But last night, I heard the whining noise. I thought it was the mask but it was too much distilled water. So I had dumb out some of the water and finally, the noise didn’t come back.

[@mikedvcneff2860]

What is the black hose going into the revivor? My model is slightly different but same brand and have the same problem along with the humidifier not heating now.

[@RicRab8]

I use a SoClean to disinfect my CPAP. The black hose is from the SoClean.

Which part of pulling apart fixed the whining noise. Pulled mine apart and gave it a good clean but still making whining noise. I believe it’s the motor that needs replacing or the bearings. I don’t know if Resmed sell the motors.

[@RandomS4nity]

My Airsense 10 just started making this horrible noise as well, though mine seems much louder. It's only 3 years old so it is outside of warranty and my insurance will only cover a replacement every 5 years. I can't wear ear plugs because the noise is clearly audible through the tube. I tried the vacuum method and it didn't work for me so I may try disassembly today.

Thx for making video. But sir could you pls point out what's the root cause to making that noise?

[@RicRab8]

Wish I knew for sure. Probably because I don't change the filter enough.

[@JoeAroner-SIWAYTV]

From my experience I believe an accumulation of dust and debris on the blower fan causes the fan blade out of balance. The fan blade at the spindle then rubs on the housing creating a plastic on plastic whine. Unfortunately the motor is sealed in the housing, so the only recourse is to try to vacuum out the dust and debris from the fan blade to alleviate the fan balance issue. I would bet the whining sound probably changes pitch according to how out of balance and speed of the fan blade. The only way to know for sure is to cut the casing around the motor, pull the fan blade off, and look for scoring marks underneath. I’m hoping my really good cleaning of the fan blades and solvent bath of isopropyl alcohol continues to cure the issue. Someday the motor will fail, and a new machine/motor will be needed.

[@JoeAroner-SIWAYTV]

20,000+ hours and my motor is dead. It was an unmistakable smell of burnt plastic. In a couple of weeks when I have time I’ll do a thorough tear down. Two sleepless nights and a no show from fedex overnight delivery and the new machine is awesome.

[@naz.s4726]

I had mine apart and blown compressor air through it and it didn't fix the problem sounds like bad bearings and can't open the motor cup. If person could open motor cup probably be able to change the bearings or lube them or something and no place sells replacement motors.

[@Daniel-ur7pj]

Good video.. I took my resmed apart and cleaned it.. problem still there.. I think I need a new motor.. problem is where to purchase one? I found a website from China that sells them but I'm not too confident in it.. has anyone purchased a new motor from a legit vendor??

[@Tabossco]

Just a FYI this machine measures pressure from incoming pressure therefore if you don't get the seal just right it will build pressure well over 20 and blow you ear drums out and maybe even cause more damage to yourself.

[@diamaunt2782]

It's not a "model Bela Vista", it's *MADE IN* Bela Vista NSW 2013, (that's a city, in New South Wales in Australia). Which machine is it actually? that's on the front, (by the name Resmed) and on the back (the REF number).

[@timbishop5136]

No need to disassemble. I just used your tip of blowing 90 PSI through the intake and exhaust and now it's whisper quiet again. Thanks!!!! I had tried compressed air can which didn't work, but 90 PSI did. (Edit). I was wrong. Noise came back during the night. Will try the full disassemble today.

Is there anywhere to buy a new motor? I don't know if blowing 90 PSI air through the motor has made the issue worse now or not I have disassembled several times and I believe maybe too much PSI has screwed up the bearings. There has to be a source for these motors

I'm a retired biomedical technician who worked on critical medical devices for decades. Nobody will sell you replacement parts unless you have a licensed shop. I have had 2 previous motors go out in the last 20 years and always considered this a bearing failure. The noise from my Airsense with 5,400 hours started last night, tried using my vaccum cleaner to pass air hard through the device. The test afterwards gave the loudest motor noise ever while it was ramping up, then it quieted down completely. Not convinced noise won't return tonight. If you do not have lots of experience opening up and closing electronics without ruining them, don't try it. I also needed an ultrasonic humidifier at times and learned that the mineral dust it spews can clog an air filter in a couple days. I found evidence the powder was leaking past my filter.

It is not very hard at all and requires minimal brain power. Just don't force anything and everything comes apart rather easily. Instead of making nasty comments perhaps you should do some brain exercises and up your game sir.
