Oxygen Troubleshooting – Why Would an Oxygen Concentrator Stop Working

Just like any other piece of electrical equipment, an oxygen concentrator can stop working after it's gotten over a certain age. You might also have instances where it can malfunction due to an outside influence, with no problems in the concentrator itself.

If an oxygen concentrator stops delivering oxygen, it could be for several different reasons. The system in an oxygen concentrator is made up of a few intricate parts that all work together to purify oxygen, so you can breathe it in.

However, before you call a maintenance technician, you can do some troubleshooting on your own to see if you can fix the problem yourself. Sometimes, the cause of a big problem can be a small, easy fix.

If the oxygen concentrator isn't working, even though it is turned on and the power light or control screen is lit up:

  • Check the power cord to make sure it's plugged in all the way.
  • Check to make sure there is power to the outlet (a breaker may be tripped).

After you've checked these to possible causes and it's still not delivering oxygen, it could be due to an internal part failure.

If you're getting a low oxygen alert:

  • Check to see if the air flow is being blocked.
  • Make sure the flow meter knob isn't closed.
  • Make sure the tubing isn't kinked.

If the oxygen purity is lower than 80%:

  • Make sure the intake vent isn't clogged or blocked. Turn the unit off and clean it if necessary.
  • The intake filter needs to be replaced or cleaned.

You can replace or clean the intake filter yourself. It should be replaced every 2 years and cleaned every 2 weeks. It can be cleaned with a mild detergent and water, and left to dry completely before being used again. If the filter looks worn out, it can be replaced sooner than the 2-year mark.

Another cause that you wouldn't be able to fix on your own, would be a weakened sieve bed. This is the component that filters the nitrogen out of the air inside the oxygen concentrator. The compressor might also be worn out and in need of a replacement.
