Hi!
My resmed airsense 10 machine will work for awhile and then it’ll suddenly completely power off and won’t come back on.  I’ll go back to check it later and it’ll turn on again.  I switched outlet plugs.  Same thing.  I checked that box plug to make sure it is completely plugged in and it still won’t come on.  So it’s an off and on thing.  Does anyone know if there’s anything else I can try?  It is only about three years old.  Luckily I had my old machine same make and model and it still works after over five years of being used. 
Thank you!

Have you swapped out power supplies?

I did initially swap them out to try but I’m not sure now if I reversed them again.
Thanks!

Hi again!
I just noticed you said your humidifier was covered.  My humidifier is still in place even though I don’t have water in it?  Could that be a problem you think?
Thanks!
