[CPAP] resmed s9 auto set error message high temperature fault refer to owners manual
Cpap Will only stay on for a few seconds before turning off and showing the error message "high temperature fault "

Pull the water tank. Depress the latch on the back and separate the humidifier from the blower unit. Then connect a 22mm CPAP hose directly to the blower. If it runs, then the humidifier is defective.

Oh, and check the intake filter on the blower unit, if it's really dirty, it could impede airflow and actually overheat the blower motor.

It may be Kaput.

HI beebsdaddy49,
WELCOME! to the forum.!
Sounds like something is overheating, take the advice in the post above mine.
Good luck with getting your machine working again and also with your CPAP therapy.
