OK, that's a relatively modern unit. It has all electronic controls and power supply. According to the manual at http://www.respironics.com/UserGuides/UserGuideMSeriesHtdHumidifier... (is this the unit that you have?), there is a blue light on the humidifier. If the light never comes on, the internal power supply or the power cord are the likely culprits. If the light comes on and stays on, I would suspect that the heating unit itself is at fault. Blinking indicates either 'a safe state condition or an AC loss error (heater plate not heating)'.

I would not recommend that you open the unit yourself, and since it is a medical device with a shock hazard potential (to you when you use it), you really do want a qualified tech to do any work on it.

I was issued a Fisher-PaykelHC150 external humidifier with my first Respironics CPAP, it has lasted through two Respironics units (it remains my backup). I'm now using a Resmed with its own integrated humidifier, which has much better reliability ratings. My mother's ancient Fisher-Paykel CPAP w/humidifier is still working after 15 years of service. If you can't fix your humidifier, you might look out for an F-P standalone unit that someone no longer needs - they're sturdy little units.

Try turning the machine on to let the heating unit warm up. This would tell you if it's working.

 

 

Bruce,

 

Most likely you are experiencing an oral leak in stage REM.
