Resmed Airsense 10 autoset for her heat malfunction

This morning it felt like I was breathing very warm air, not enough to be uncomfortable but it definitely felt unusually warm. Then as I was disconnecting the climate air tube and removing the humidifier, a message flashed on the LED screen something like "electronic heat malfunction, unit will run without heat" . I can't recall the exact wording. The message was on the screen for perhaps a minute and then disappeared. When I removed the humidifier from the machine, the water was very warm and the bottom of the humidifier chamber quite hot. Usually I don't disconnect the parts immediately upon awakening but I did this morning. So I don't know if normally if I would have pulled out the humidifier as soon as I woke up if it would feel hot. But it did this morning. I have been waiting all day for the DME to call me back and at this point it looks like I won't be getting a callback today. I just tried running the warm-up option on the machine. The water did not get warm and the inside bottom of the humidifier chamber was maybe a tad warmer than room temp but not enough that I wasn't even sure if I was imagining it. I guess I am going to go ahead and use the machine tonight and if it is very uncomfortable, I'll stop using it. I think the machine is defective. I wondered if anyone else might have encountered this issue.

I don't know about the error message you saw, but yes, it's normal for the water and the bottom of the humidifier to be warm. When you have the machine set to provide humidity, it does that by warming the water, and the heating element is in the bottom of the humidifier. The air passes over the warm water and picks up moisture.

Thank you, Hopeful... You are right, of course, the unit does heat the water to generate the humidity I guess... So that part was probably normal. I'll see how tonight goes and if the humidity doesn't work, if I can tolerate the CPAP, I will do so but otherwise I will just skip tonight, much as I hate to do that. I will take the machine back to the DME's office tomorrow and see what they have to say. It's very aggravating that I called them as soon as they opened this morning and in the course of a whole day, no one got around to calling me back. I even called them toward the end of the day to make sure I would get a call and they said I am on their "call list" and I would definitely get a call... oh well...

My DME is within driving distance.
If such a thing happened to me, I would call to inform them that I would soon be in--and why.
Telephone tag has no place in medicine.

ChunkyFrog - I am going to do just as you suggest today. I did use the machine last night and eventually the heating element did warm up the humidifier. It seemed to take a long time and I'm not sure at what point it turned on as I was asleep. I used the machine for not quite two hours, woke up and there was no heat at that point. I took off my mask, slept a bit more, then decided to try again and eventually it did heat up. However, I am concerned because there is no explanation of why that message displayed, I don't know when it might happen again, I don't want the warranty to run out and then have it happen again, and could there be a fire hazard... I sent an Email message to Resmed this morning and I am going to take the machine to the DME's office today as well. I thought I had found a DME that was responsive to customers after an initial horrible experience with the first DME I visited so I am very disappointed in their lack of response but, from what I have read on this support board, this experience of lack of responsiveness is likely pretty common, sad to say.

Update - I took the CPAP machine to the DME's office. They tested it and said the problem was a defective ClimateLineAir hose, the heated hose part of the equipment, and issued me a new hose. It makes sense. Hopefully that is the end of this problem. Interestingly, the response to my Email message to Resmed was that they only assist with MyAir issues, not therapy, equipment, etc. I was surprised. I can understand them not responding to therapy questions, but I would think a malfunction message on their equipment would be something the manufacturer would respond about. They directed me to my DME supplier. So much for getting assistance from Resmed...
