[CPAP] Is my machine about to fail? Can I fix it?
#1
Hello!

I think my machine is sort of ancient. I bought it used on eBay back when you could do that, maybe ten years ago, or more. It's a Respironics Remstar Plus LX.

(I do have a prescription, but medical equipment is not a covered benefit with my health insurance. When I found out the prices from the medical supply company, I just bought my own.)

It's starting to make a high-pitched whining noise that it didn't make before. Does that mean it's going to fail soon? I'm wondering if I could do something to fix it, or make it last a little longer. I'm handy with mechanical things.

If it's failing, I suppose I ought to get a new one while it still works.

Suggestions and ideas, please?

Thanks

A machine of that age, with new technology that is out there, I would purchase another machine. It has lasted longer than I would have thought it would. You know your financial situation best of all.

BTW, I have not heard of an insurance company not covering these machines. I have heard of high deductibles that causes someone to have to buy their own. Maybe your insurance company will catch up to the current times soon............or maybe they won't. Who knows anymore.

This is JMHO.

Hi winky, welcome aboard
Its cheaper to buy a new machine than spending money on repairs and beside machines have comes a long way since then
I doubt you can buy CPAP machines on ebay these days. You can get a good deal from Supplier #2 for used and new machines (both comes with a warranty). Suppliers List http://www.apneaboard.com/forums/Thread-...plier-List

Read this wiki before looking for a new machines

You're right. OTOH, they are easy to find on CraigsList, if you know what to shop for. I'm counting the pennies. So many people are these days.

I'll take a look. Thanks.

Hi winky,
WELCOME! to the forum.!
If you can get a new machine, you would probably be much better served. The technology has improved in the newer ones. You might try to get one now while the one you have is still working.
Best of luck to you.

Welcome fellow hosehead.

Be sure to ask questions, and get info if/when you get a new(er) machine. Mine too is fairly old, and I understand the need to count nickels...

If you are up to it, you might want to try looking inside your machine if you can get a copy of the service manual. This may not be for everyone, but in my case we didn't have much to lose since it wouldn't turn on consistently and was well beyond the warranty period.

My wife's REMstar plus with C-Flex 250P was having trouble turning on. Nine times out of ten, instead of turning on, it would give her an error beep (no error code) and the screen would say that it needed service. She had it visually inspected by the local supplier and they said she needed a new one. Unfortunately, it was only about 4 years into our 5 year health care replacement cycle. (This machine has the SD card slot, but no card is being used.)

Thanks to the Apnea Board Forums, I found the pdf file of the service manual in the "LINKS to Members-Only Files" area. Armed with a couple of Torx screwdriver tips and the guidance of the pdf file, I was able to carefully disassemble the machine. The REMstar manual has lots of images with all the key items pointed out so it was really straight forward. The hardest part for that model was prying off the knob on the top of the machine. Everything else came apart easily with the Torx screwdriver. I discovered that the insides were pretty dusty. There was even a spider web on the pc board. I used some compressed air to blow off all the dust, disassembled it a little more and blew the dust out of the rest of the insides. Assembly was the reverse of disassembly. I made sure that all the seals were sealing against whatever they needed to.

All the screws screw into plastic, so it's a good idea to start each screw into its hole by first slowly turning it counter-clockwise until you feel it raise up a little and then drop down into the existing thread grooves. Then you can start turning it clockwise to tighten it down. This helps to ensure you don't accidentally cross-thread the screw, which would weaken the hole.

Anyway, for my wife's machine, that's all it took to get it to fire up the first time she turns it on now.

Thanks again to the forum for putting together the manuals section.

try some oil on the motor bearings, that will be the most likely source for the noise.
I use automatic transmission oil for small motor bearings, not sure being a med device if that would be a good one to use.
search the net for med grade oil for breathing devices.
if used sparingly the auto trans oil should work

Even if you fix it, start searching Craigslist for a better one with full data. Depending on where you are, it may take several months to find a good deal.
