AirSense 10 error codes and error messages.

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 software. This is just another reason why you should use a ResMed Authorized Service Center such as us!

This is caused by, you guessed it, the power cord not being fully inserted into the back of the machine. Sometimes the seal around the power input port on the back becomes warped and folded over. This makes it difficult to plug in the power supply. When plugging in the power supply to the back of the machine, hold the front with one hand, and twist while pushing the power supply into the power input port. If this doesn’t help, then you will need to have the whole board replaced, so try harder 🙂

Your SD card has become corrupted. It may be possible to fix this by putting the SD card in a computer (that has an SD card port) and reformatting the SD card. If this doesn’t work, then you can purchase a new SD card pretty much anywhere.

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 precedes one of the following error codes

This is a hardware issue, caused by either a faulty blower motor or pressure sensor on the main PC board. A part will need to be replaced and unit calibrated to fix this issue.

This is a pressure sensor fault. It is possible that the CPAP needs to be recalibrated. If that doesn’t solve the problem, then you will need a new main PC board. In either instance, it will need to be returned to a ResMed Authorized Service Center such as us for corrective action.

This is a pressure sensor fault. It is possible that the CPAP needs to be recalibrated. If that doesn’t solve the problem, then you will need a new main PC board. In either instance, it will need to be returned to a ResMed Authorized Service Center such as us for corrective action.

This error message refers to the main PC board being over temperature. This is typically corrected by unplugging your CPAP machine and allowing it to cool down. If you continue to have this error message, then it will need to come in for service.

The voltage going to the blower motor is high. It could be caused by the power supply, blower motor, or main PC board. This will need to come in for a free evaluation to determine the exact cause and corrective measure.

This refers to a motor stall issue with the software. You will need either the blower motor or main PC board replaced.

Error 007, not to be confused with James Bond, is a blower motor fault. 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. This will need to be sent to a ResMed Authorized Repair Center to be serviced.

This is a software data issue. The main PC board will need to be replaced.

This is a calibration data error. This is 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 error code is not very helpful. It is a non-specified error that will need either the blower motor or main PC board replaced.

The flow sensor is faulty. This requires the main PC board to be replaced.
