ResMed CPAP Motor Life Exceeded: What It Means and What to Do

Quick Answer

The Motor Life Exceeded message on the ResMed AirSense 10 appears after the internal blower motor accumulates roughly 20,000 hours of operation, which translates to about 7-8 years of nightly use at 7 hours per night. The device does not stop working when this message appears - it continues to deliver therapy at the prescribed pressure.

The Motor Life Exceeded message on the ResMed AirSense 10 appears after the internal blower motor accumulates roughly 20,000 hours of operation, which translates to about 7-8 years of nightly use at 7 hours per night. The device does not stop working when this message appears - it continues to deliver therapy at the prescribed pressure. However, ResMed recommends replacement because motor performance may degrade gradually, delivering slightly less accurate pressure over time. Most insurance plans cover a new CPAP every 5 years, so many users are already eligible for a replacement before this counter trips.

Frequently Asked Questions

Can I still use my CPAP after Motor Life Exceeded?
Yes. The device continues to deliver therapy normally. Motor Life Exceeded is a maintenance reminder, not a shutdown command. However, ResMed recommends replacement because motor precision may degrade gradually over time, potentially delivering slightly inaccurate pressure.
Can I reset the Motor Life Exceeded counter?
No. The motor hour counter is stored in non-volatile memory inside the device and cannot be reset through the user menu or even a factory reset. Only ResMed service centers can access this counter, and they will not reset it - it exists for patient safety tracking.
How do I check how many hours are on my CPAP motor?
On the AirSense 10, enter the clinical menu by holding the Home button and the dial simultaneously for 3 seconds, then navigate to Device Info to see cumulative usage hours. On the AirSense 11, go to Settings > My Device > Device Info. Your myAir app also shows total usage days.
