My Airsense 10 is about 2 years old. My humidifier heater quit. I pulled the cover and checked the fuse and it is good. I don’t have a schematic to check the test points. Could you give me some info on the heater? Thanks!
Bg Higg by checked the fuse I assume your are referring to the one under the heater unit like shown on here Data on the heater is not freely available so I would go ahead and replace the heater on use a bench power supply to see if that could run the heater.
