Are these machines repairable (within reason)?

JayDee · Post by **JayDee** » Fri Jul 05, 2019 4:48 pm

Saw another thread about disposing of old machines and possibly donating them...

I'm fairly handy with a wide variety of things and electronics tinkering is something I'm familiar with.

I've never had a machine apart, but I can imagine it's like most all electronics these days and is modular. Has anyone ever had one apart to see if the major components can be replaced if they fail? I'm presuming the logic board is proprietary and likely unobtainable unless scavenged out of another unit, but what about all the other parts -- the pump/motor/pressure sensors? It's sometimes surprising what obscure parts you can find at companies like Mouser, Jameco, Digikey, etc.

Not planning on doing anything and my machines just fine. I'm just wondering if they can be repaired/refurbished instead of trashed when they fail. At that point, what do you have to lose? Might as well try something, even if just to tinker.

Thanks,

Everything is repairable by someone, whether it's cost effective, is another matter. That's why they make car crushers.

Bear Bones XPAPs that didn't collect full data weren't worth much when NEW! Best to let the Sleep dogs lie. There are places to have them repaired, Wal-Mart doesn't doesn't sell the needed parts or tools or softwire or diagrams. Jim

Yes, very modular,on the resmed s9 series,the only diff between models was the firmware... Other parts could be swapped, or put an autoset board in an escape as an upgrade

Aren't you gonna link your step by step s9 dismantling?

I haven't gotten my paws on an air series machine, but I have seen some pics that grayghost4 sent me where he was disassembling them and swapping parts around.

I've taken apart a S9 elite, autoset, vpap auto, adapt and Tx.. they're all the same inside.... even the boards, the only difference is firmware.

That's a little bit surprising. I would have expected some proprietary hardware, if only as an attempt to stymie or slow down competitors...

The things seem fairly long-lived just judging by forum comments. I could be wrong, but I get the impression they typically exceed their expected service life and lemons are rare. Or, perhaps the odds are you will upgrade to a new machine before your old one fails.

Well, you could argue that the blower in the Resmed is proprietary... it's certainly big improvement over the one in the Respironics machines.

Some of the old models are well past their '5 year' mark, whether the new ones will last as long... don't know yet

If they were well made the warranty would be 5 years. Jim

If they weren't well made, they wouldn't *routinely* last for over five years.

Just because boards can be swapped between different products from the same manufacturer doesn't make those boards any less proprietary. That just makes their products less costly to make and maintain if they're not redesigning the internal boards for every product. And ResMed still owns the IP on the boards. Don't know how many patents that they might have, but companies like ResMed usually get the most patents that they can manage to get. Companies that I've worked for paid bounties to employees for getting patents.

If the Boards are all the same, and the firmware is the only difference, that's a huge profit for code seeing as the same cost for 1000 units as a million of them. Jim

Dim"s some costly 1's and 0"s!!!!
