How to Reset an Oxygen Concentrator

An oxygen concentrator is a medical device that provides supplemental oxygen by filtering ambient air to deliver a stream of 90% to 95% pure oxygen. These electric or battery-powered machines rely on complex internal components and can occasionally experience operational glitches. A user might need to perform a reset, which is a controlled power cycle, in response to an unexpected shutdown, a persistent alarm, or an error code. Performing a manual reset often clears temporary software conflicts or sensor errors, restoring the device before a professional service call is needed.

Essential Checks Before Attempting a Reset

Before initiating a system reset, it is helpful to eliminate simple external factors that could be triggering an alarm or preventing the unit from working correctly. Ensure the power cord is securely plugged into both the concentrator and the wall outlet, and confirm the electrical outlet is active by testing it with another small appliance. Power supply issues frequently cause operational faults, so also check if the circuit breaker on the machine or in the home electrical panel has tripped.

Next, examine the air intake filter, which prevents dust and debris from entering the internal mechanism. A clogged filter can significantly restrict airflow and trigger a low-flow alarm. While filters should be cleaned or replaced per the manufacturer’s schedule, a quick inspection for excessive lint or pet hair is worthwhile. Finally, inspect the oxygen tubing and nasal cannula for any twists or kinks that could impede delivery, and confirm all connections, including the humidifier bottle if used, are secure and leak-free.

Step-by-Step Guide to Resetting Your Concentrator

Once external issues have been ruled out, the next step is to perform a controlled power cycle. Start by turning the unit off using the main power switch or button, and then immediately unplug the power cord from the wall outlet. This action ensures that the device’s internal components are completely disconnected from the electrical supply, which is necessary to clear any residual charge or memory errors.

For portable oxygen concentrators that use a removable battery, remove the battery pack at this time. Allow the machine to sit in this fully powered-down state for a specific period, typically between five and ten minutes. This waiting period allows the internal computer boards and sensors to cool down and fully stabilize.

After the specified waiting time has passed, plug the power cord directly back into a working wall outlet, avoiding the use of extension cords or power strips. If a battery was removed from a portable unit, reinsert it securely before attempting to power the device back on. Press the power button to restart the concentrator and observe the display screen for any signs of the previous error code or alarm. If the unit powers on and resumes normal operation, allow it to run for at least 15 minutes to confirm the oxygen purity and flow are stable.

If the generic power cycle does not resolve the issue, consult the specific device manual. Some advanced units may have a dedicated physical or digital reset function, though this is less common than the simple power cycle. If the machine continues to display an error or fails to power on correctly after this process, it indicates a deeper issue that requires professional attention.

When to Contact Your Equipment Provider

When a simple reset fails to clear the problem, or if the unit exhibits signs of a more serious malfunction, contact your medical equipment provider for assistance. A persistent error code that reappears immediately after the power cycle indicates a failure within an internal component, such as the compressor or the sieve beds, which cannot be fixed by the user. Similarly, a complete inability for the concentrator to power on after a confirmed reset sequence suggests a significant electrical failure.

Any sudden, persistent, or unusually loud noises, such as a high-pitched grinding or a sustained, rhythmic knocking sound, should prompt an immediate call, as these often signal mechanical trouble. If the exterior casing of the unit is unusually hot to the touch, or if you detect any smell of burning plastic or smoke, immediately disconnect the unit from the wall and contact the provider. These signs can indicate overheating or an electrical short within the device.

While waiting for assistance, switch immediately to your prescribed backup oxygen source to ensure your respiratory needs are met. When you contact your provider, be prepared to clearly state the exact error code or message displayed and describe the troubleshooting steps you have already performed. Documenting the specific error code is helpful, as it provides technicians with the information needed to diagnose the issue and arrange for repair or replacement.
