Repairing a sleep apnea device?

I hope I am wrong: It could be the blower motor itsself at the end of its life ... running for years and has collected microscopic dust in its bearings. If it has to start working it needs a lot more of Ampere. I remember this behavior of old ventilators.

These power supplies tend to die completely or they continuously can't deliver enough power .

One of the easiest and yet toughest things in the world to find is an intermittent problem with your electronics. Over the years I have seen power supplies that we have set up in our test jig, where a relay drops out if the power fails for even a moment, in order to show us that the power did indeed fail at some point. Works great but does not do anything (or little) for measuring and verifying output voltage over time AND I am afraid I don't know what the power requirements are for your particular blower. Once determined one can test for voltage and current output.... or voltage under load. An intermittent problem with electronics is very VERY frustrating. If you can get your hands on another power supply (even if it is only one that puts out the voltage and current you require... if you were in my area I could loan you one for a week but it weighs a ton) you could cut off the power cord and use it with the variable output supply which would confirm power supply issue (yes/no) in a hurry. As the OP said, I too am not convinced it is a power supply issue for sure. It could be something as simple as a corroded fuse socket in the blower or something as complex as an electronics issue or cold solder joint in the blower OR power supply. With the cost of blowers today, if you or a friend are at all handy (look for a ham radio callsign of someone over 40) you can at least get an idea of where the problem might reside. I'd think it worth the effort for a spare machine but that's just me and I'm getting lazy as I grow older. Good luck in any event.

Revisiting an old thread mostly because I'm just looking for info to still get my old unit repaired - to be a backup.

It's not the power brick. Got a brand new one, same result.

So, after some hassles with the new bipap, i'm wanting a backup unit again. But just thought I'd update on this, for whatever reason as I'm searching for repair companies.

The provider of the new unit won't touch it - says respironics no longer looks at bipap auto m series because they're "too old". Seems like "needs service" would still command some respect and help.

Anyone heard of these folks? Good/bad, repair thoughts?

I just called them, and was impressed by the phone call response. (I am very rarely impressed, I'm picky.)

So sounds like I'll be sending Advans my unit on Monday, but would still like comments if anyone has thoughts.

Sorry if I did something wrong.

Sorry if I did something wrong.

I don't think you did anything "wrong", except possibly not scrutinizing the forum rules sufficiently, but I have to admit I didn't do that either.

So perhaps you shouldn't feel chastised, but politely corrected. We all make mistakes.
