Every few weeks my resmed s9 vpap asv has episodes of abnormal interruptions of the blowing process, which first wakes me up and then does not allow me to fall asleep.
It goes through a repeated cycle of “stop blowing for 0.5 sec, resume blowing, stop blowing for 0.5 sec, etc” for about 20 min.
After power off/on (sometimes have to repeat the power off/on a few times) s9 starts blowing normally (without the interruptions) and continues for a few weeks until another abnormal episode.
Does anybody have an explanation or a similar experience?
I appreciate your comments.

I have no idea what might be going on with your machine. But if it were mine, I'd take it back to the DME and see if I could recreate the problem for them. If it needs to be serviced, the DME should be able to provide you with a loaner machine until yours can be repaired.
The DME (I keep hoping some are really good) may have seen this before and know what it is.
