Hi 1captnronrosser, Welcome to the forum.

The only thing I could find stated that this is a component failure.

Have you tried the clinician's manual to see if it lists anything?
Here is the link to obtain it:
Additionally, this is the same link that appears at the top of the page,

That machine is 3-4 generations old and probably needs to be replaced. That machine is at least 10 years old (discontinued 2006).

Hi 1captnronrosser,
WELCOME! to the forum.!
You might consider getting a mew machine if you can, the technology is much improved with the newer machines.
Good luck to you with your CPAP therapy.
Hang in there for more responses to your post.
