Major Reasons Why an Oxygen Concentrator Is Not Operating

　　When this situation occurs, the first step is to check whether the power plug of the industrial oxygen generator is properly inserted into the power outlet. If it is not, insert it firmly and then try turning on the home oxygen concentrator. Alternatively, the power outlet itself may be de-energized; in this case, use a voltage tester to verify. If neither of these issues is present, you should consider whether the home oxygen concentrator has activated its overload protection, which is designed to intelligently detect and protect the device. To rule out this possibility, press the reset button on the home oxygen concentrator’s overload protector.

　　If the issue remains unresolved, it could be due to loose wiring on the oxygen concentrator. In this case, all connections should be carefully reconnected and rechecked. If the problem persists, it may indicate an internal wiring fault that requires return to the manufacturer for repair. Users should promptly contact the retailer to arrange for timely resolution and ensure proper operation going forward.

　　In such cases, the issue may be that the air compressor’s thermal protector has been activated. If a home oxygen concentrator shuts down after running continuously for 45 minutes upon startup, it is imperative to contact the vendor promptly for repair. Alternatively, the air intake or outlet may be blocked. In this situation, first clean the filters thoroughly and then inspect the intake and outlet to ensure there are no obstructions impeding airflow or oxygen discharge, and check whether any material is obstructing the unit’s heat dissipation. If none of these conditions apply, the problem could be due to room temperature: if the ambient temperature falls below 5°C, the unit must be warmed up to ensure normal operation.
