ResMed AirSense 10: pressure suddenly rises, then shuts down, and shows error

Tue, 25 Nov 2025 14:50:35 -0700

During normal use, and typically during the first 10 to 20 minutes of operation, the CPAP pressure will suddenly rise greatly for 5 to 10 seconds and then the machine will shut down. The screen shows: Error: System fault, refer to user guide, Error 001. From doing a little research on the problem, I understand that this error refers to either a faulty blower motor, or pressure sensor. The blower sounds perfectly normal during usual operation, and it was replaced by Resmed service just over a year ago, so I'm inclined to think the problem is likely not the blower motor. Is there any way to determine if the problem is the blower, or the pressure sensor?

ResMed CPAP: Loud whine when working

Tue, 23 Apr 2024 14:30:51 -0700

My ResMed AirSense 10 CPAP makes a whining noise when it's on. The whine rises in pitch when I remove the nose pillows and as I breathe in and out, and the whine can be louder or softer on different nights. Do I need a new blower?

ResMed AirSense 10: Smartstart failing. Shuts off abruptly mid sleep.

Tue, 23 Apr 2024 14:29:40 -0700

Out of warranty. Exploring Diy repair possibilities.

It is harshly thunking off mid sleep. Wakes me up.

Also, doesn't start up promptly. Takes multiple really deep breaths to get it on.

I presume there is a sensor going bad or needs cleaning.

4 years 10 month old machine used daily. No repairs of any sort to date. Got it new.

ResMed AirSense 10: Needing to hardwire power supply into machine

Mon, 14 Aug 2023 16:45:06 -0700

My dog chewed the connector off that goes into the back of my machine. I need to hardwire the power supply into the machine as I am limited on time and cannot wait for a new power supply. Can you please tell me which color in the power supply goes to which color inside the machine? The power supply has 3 lines. Black, white and bare. The machine has 3 wires. Black, white and red. I do not want to assume to match black to black, white to white and red to bare as the configuration may change within the connection at the back of the machine. This will only be a temporary repair until a new power supply is delivered then will be soldered and heat shrink back to its near original condition. Please help if possible as this is very time sensitive. Thank you.
