Why Does My Resmed Keep Turning Off: Common Causes and Solutions

Are you experiencing frequent issues with your Resmed device constantly turning off? This can be frustrating and disrupt your sleep apnea treatment. Understanding the potential causes behind this problem can help you find an effective solution. In this article, we will explore the common reasons why your Resmed keeps turning off and provide practical solutions to address the issue.

Faulty Power Connection

A common reason for your Resmed device turning off unexpectedly is a faulty power connection. Check the power cord and ensure it is securely plugged into both the power outlet and the Resmed device. Sometimes, the cord might get loose or damaged, leading to intermittent power supply, which results in the device turning off. If you notice any issues with the power cord, consider replacing it with a new one.


Resmed devices can occasionally overheat, causing them to shut down as a safety measure. Various factors can contribute to overheating, including inadequate ventilation, dust accumulation, or placing the device on a surface that traps heat. To prevent overheating, make sure your Resmed device is placed on a flat and sturdy surface with sufficient airflow. Regularly clean the device’s exterior using a soft cloth to remove any dust or debris that might obstruct proper airflow.

Software or Firmware Issues

Software or firmware glitches can also cause your Resmed device to turn off unexpectedly. Check if your device’s software is up-to-date and consider updating it if necessary. Resmed often releases software or firmware updates to address known issues and enhance the device’s performance. Visit Resmed’s official website or contact their customer support for guidance on updating your device’s software. Performing a software/firmware update may resolve the issue you’re experiencing.

Low Battery or Power Supply

If you are using a portable Resmed device with a battery, it’s important to ensure that the battery has sufficient charge. A low battery can cause the device to shut down unexpectedly. Replace the battery or recharge it fully using the provided charger. Additionally, if you are using an AC power supply, verify that it is functioning correctly. Faulty power supplies may not provide a stable power source, leading to frequent shutdowns.

Mask or Tube Issues

Sometimes, issues with your mask or tube can trigger your Resmed device to turn off. Ensure that the mask and tube are properly connected and secure. Loose connections or damaged components can interrupt the airflow, causing the device to shut down. Inspect the mask and tube for any signs of wear and tear, such as cracks or leaks. Replace any damaged parts to ensure proper functioning of your Resmed device.

In conclusion, there can be various reasons why your Resmed device keeps turning off. By checking the power connection, addressing overheating issues, updating software/firmware, ensuring proper battery or power supply, and inspecting mask/tube components, you can troubleshoot and resolve the problem. If the issue persists, it is advisable to reach out to Resmed’s customer support for further assistance. By resolving this issue promptly, you can continue to receive uninterrupted sleep apnea therapy and improve your sleep quality.
