Popping Cracking Sound
I am a fairly recent user of the ResMed S9 AutoSet with a H5I Humidifier. Unfortunately, my machine makes a popping/cracking sound 24/7. When I spoke with my provider they first suggested that I turn the humidifier. I did the sound did not go away. They then exchanged the humidifier. The sound did not go away. They then exchanged the entire unit, and yes, the problem is still there. I am now in the processing of changing manufacturers because my confidence level has been shot. BTW, they had at least one other customer that had the same problem. Today, I googled and found out the S8 was recalled for the same problem.

Is anyone else having this problem? The discussion on the one that turned off in the middle of the night sounds like it was also part of the S8 recall: electrical failure such as intermittent power, cracking sounds, sparking, and charred smell.

Hi jbroileshi01,
WELCOME! to the forum.!
I haven't had that problem but hang in there for more responses to your post and best of luck getting this straightened out.

RE: Popping Cracking Sound
Hi,

is the popping sound coming from the tube or mask? do you have water inside the tube or mask. I had similar incident and found out that my humidity level is high thus creating a rain out. the water inside pushed to my mask and creating a popping sound. One thing though to consider is to keep the bottom of the water tub dry. hope this helps.

try to check as well if the s9 is creating the sound by covering the air outlet on your humidifier. if not, then the problem lies on the tube or mask.

cheers.

make sure that you keep your power supply somewhere other than right next to your CPAP machine.

RE: Popping Cracking Sound
The S8 is a different animal. The S8 has an internal power supply where the 120 VAC line goes directly into the machine. S9's have an external power brick. I think one cannot relate the S8 recall to the S9 machines.

It is odd that to OP says the S9 makes a noise 24/7 -- even more odd is that 2 consecutive machines would make the noise. Nothing should be moving or turning during idle periods after the cool-down period. Is the machine on a surface that might amplify very slight sounds? Back to basics -- what about when it's insitu; but the power cable is disconnected?

Regarding ResMed's advice to keep the power brick away from the machine; That's just CYA on ResMed's part. The machine has to be resistant to levels of EMI seen in proximity to the power brick; or they would be getting sued by patients whose machines acted up from the multiple EMI sources in our modern society.

I returned two S9's because there were problems with it and they claimed it was because I kept the power supply on the same table with the machine (that is what they told me after the 2nd failure and replacement). With the replacement, I put the power supply on the floor and never had an issue with that machine. So, who knows?

I wonder if the EMI put out by the transformer is enough to set off the little speaker in there that beeps at you. They probably never bothered or thought to shield a speaker (or it might have cut into the profits by a nickle a unit!)!

As always, YMMV! You do not have to agree or disagree, I am not a professional so my mental meanderings are simply recollections of things from my own life.

These power supplies are switchers. Power supplies have moved away from transformer, rectifier, filter, regulators to switching supplies. The efficiency is much higher.

EMI was one of my multifaceted engineering disciplines.

Most switching supplies have shielding to prevent their interference with communications devices.

My S8 is between my DVD player and two DECT 6 cordless phones with no ill effects.

RE: Popping Cracking Sound
I bought my S9 used and it has been flawless, I had heard very little negative on this model. Actually the only thing I had heard was that it is the near the top standard for this equipment. If the humidifier is even in question pull it off and run the main unit by itself. The odds are against having two units with the same problem but anything is possible. Hope you get it figured out soon, but as for me if I see another used one reasonably priced I'm jumping on it just in case (or when) I would have a problem with mine. Tell us more about when this makes noise, if it was power you would think the whole thing would go off or reset. The thing I would think could make noise would be the blower but that would be obvious with pressure jumping or blades crashing or something.
Good luck. Doc
