Oxygen concentrators are often a very reliable life-saving device! They can run 24/7 if needed. The first oxygen concentrators in the 1970s weighed hundreds of pounds and looked like furniture in a living room.

　　While very reliable overall, these are still really machines with many moving parts. These parts wear out and inevitably fail as you age them. The good news is that you can always rebuild a machine for many years until it eventually becomes obsolete. Let's talk about some common problems with oxygen concentrators.

　　Oxygen Concentrator Hypoxic Lamp: The hypoxic indicator light usually indicates that the oxygen coming out of the machine is less than 87% pure oxygen.

　　Oxygen concentrator machine won't turn on: let's take a closer look at this. Turn on your machine. Do you feel air blowing out of the exhaust vents on the back or bottom of the machine? If so, it probably means your motor is broken. It could also mean that your motor starting capacitor is faulty.

　　The oxygen concentrator machine runs for a while, gets very hot, and then shuts down: this obviously means your machine is running too hot. In most cases, your cooling fan has failed.
