For instance, last night I got ready for bed, put mask on, expected SmartStart to engage; when it did not, I pressed the "start/stop" button, and my AirSense 10 went dark. Nothing I tried could revive it. I checked the tube, humidifier, etc. Unplugged the machine, waited a few minutes, plugged it back in, etc. Nothing could get the display to light up--and I had power (cord transformer was lit).
So I used my old backup machine last night (worked fine in the same outlet). This morning, when I tried to restart the AirSense 10 (after unplugging and replugging it), it reset itself and started fine. This is very similar to my last "would not start" episode.
My owner's manual was no help. The tech I spoke with at Lincare was no help. The suggestions in the FAQs on the ResMed site had all been tried by me (or did not apply).
My online search turned up no theories other than a thread about the AirSense 9 that said perhaps the transformer on my cord was too close to the machine, and its heat made the CPAP too warm and it shut off from overheading. That seems unlikely to me, though I will move the transformer to a separate shelf from the AirSense 10. If that turns out to be the solution, I guess I'll know it is, maybe, if it never happens again.
Does anyone have any other theories or suggested solutions? Thanks.
