Are you using the ramp feature - not sure if that's what you mean by 'warm-up mode'. #4 is the default low for machines and if you have a long ramp time to 'reach' 7, it's just wasting time as you delay therapy rather than enhance it. Only if your min. setting was e.g. 10 or higher would you bother...

Have you tried raising the min. pressure to 7 for a couple of nights - it could just be a bit low for you. I haven't tried adjusting anything yet. I may try that if this keeps up and I don't have any other clues, but it seems like I'd be struggling during the low pressure warm-up mode if it was pur...

A handful of times in the past couple of weeks I've woken up with the sensation of struggling to get enough air. It almost feels like a power outage, but the machine's still on. I'm usually not awake enough to process what's happening, but this morning I was a bit more coherent. I was breathing comf...

...extended warranty... Extended warranties are, overall, not worth the cost. If they were, whoever's offering them would be losing money. It only benefits you if the device dies in its 4th or 5th year, when most still run just fine well after 5 years (and that's assuming there aren't loopholes/exc...

did you look over the ifixit link that takes you directly to the instructions on how to open and fix stuff yourself? I see nothing there that even suggests methods to fix a failing motor. it’s not terribly difficult. If you're talking about installing a replacement motor/pneumatic block, then you'r...

I ran across Altra, another repair company who lists common repair prices on their website . $275 for a (presumably) new motor, installed, shipped, and warrantied for a year sounds way more attractive than the used motors for $200 with little or no warranty that I was finding. I suspect acbio's pric...

I'm not disparaging acbio for charging a diagnostic fee. The fee I was given ($65 in this case, ymmv) seems entirely reasonable (probably even generous) to cover shipping of the machine and a tech's time. I wish they'd have been willing to give me a non-binding ballpark estimate, but I can understan...

You might give acbio.com a call about potential cost of repair. I did so today; they refuse to give a ballpark guess. Their process is to ship them the machine, then if you decline their estimate, they charge a diagnostic fee and ship it back. I ran across another company that buys used machines to...

6 mos. past the warranty and my AirSense 10 has started the obnoxious noise reported my many others that seems to be a failing motor. My DME says they could send it back to ResMed, but no one knows what the repair would cost until it comes back with the invoice due--they're guessing $500. There does...
