ResMed AirSense 11 problems and with possible causes and corrective action.
This message will display when you reach 21,900 hours of use (5 years, 12 hours per day). That is the design life of the blower motor and replacement is recommended. When we replace a blower motor, we change the blower hours to 0, which will stop the message from displaying (at least until another 21,900 hours). Changing the blower hours can only be completed through the ResMed computerized service software. This is just another reason why you should use Altra CPAP Repair, a ResMed Authorized Service Center!
This is typically an issue with one of you disposable CPAP supplies such as the humidifier water chamber not being fully inserted, mask not creating a seal, or tubing not connected properly.
This is caused by either a faulter heater plate or main PCA board.
This typically precedes one of the following error codes
This is a blower motor issue. The blower motor will need to be replaced and unit calibrated to fix this issue.
This is a pressure sensor fault. It is possible that the CPAP just needs to be recalibrated, but more times than not, you will need a new main PC board. It will need to be returned to a ResMed Authorized Service Center such as us for corrective action.
There are several potential issues causing the error 4 message and potential remedies.
- Environment is too hot.
- Ensure device is not covered.
- Allow device to cool before re-use.
- Disconnect the power supply then reconnect to restart the device.
- Blocked filter
- Replace filter.
- Allow device to cool down.
- Disconnect the power supply then reconnect to restart the device.
- Air tubing blocked
- Check air tubing and remove any blockages. Press ok to restart therapy.
- Water in the air tubing
- Check air tubing and remove any blockages. Press ok to restart therapy.
- Faulty main PCA board. This is the most likely cause of error 4. The main pc board will need to be replaced.
There are several potential issues causing the error code 5.
- Faulty power supply.
- Faulty blower motor
- Faulty main pc board
This is typically caused by the blower motor, however, there are some instances where it could be the board.
This refers to a motor stall issue with the software. You will need either the blower motor or main PC board replaced.
This will need the blower motor replaced.
Another blower motor related error. This will need the blower motor replaced.
This is related to the main PC board, which will need to be replaced.
The flow sensor is stuck. The flow sensor is attached to the main PC board, requiring the whole board to be replaced.
The flow sensor is stuck. The flow sensor is attached to the main PC board, requiring the whole board to be replaced.
The flow sensor is not relaying information to the board. The flow sensor is attached to the main PC board, requiring the whole board to be replaced.
The pressure sensor is not reading properly. This can be caused by the device being out of calibration, the sensor becoming dislodged from its seal, or being faulty. If calibration doesn’t correct this problem, then the main PC board will need to be replaced.
A pressure sensor issue. This can be caused by the device being out of calibration, the sensor becoming dislodged from its seal, or being faulty. If calibration doesn’t correct this problem, then the main PC board will need to be replaced.

This is a software data issue. The main PC board will need to be replaced.
Data corruption. This may be caused by the device being out of calibration. If calibration doesn’t correct this problem, then the main PC board will need to be replaced.
This is a board issue. The main pc board will need to be replaced.
The pressure sensor is faulty. This requires the main PC board to be replaced.
This is a board issue. The main pc board will need to be replaced.
