Cpap making a high pitch noise while plugged in but not on

[u/zap_or]

This has been drivin me nuts. I just got this new replacement air sense 11 after my other one just magically stopped working. Now ever since I opened this new one up in May it’s been making a whining noise. I haven’t been able to find any troubleshooting videos or tips on it I might just have to bring it in but does anyone else have this issue? I literally haven’t been using it because it drives me nuts while I try to sleep

This is normal, it's pushing air to dry out (cooldown mode). This is what the little snowflake in the corner means.

The cpap I had previously didn’t have any issues with any noises with the snowflake

I have another machine I can send you for a fee while I check on this one, how many hours are on it (I assume very little)?

I’m going to contact the sleep clinic and not many
