The yellow light indicates the O2 Between 73% to 85%.  The Owners Manual is available HERE.

These are some possible causes and fixes from the manual.

2. Kinked or blocked tubing, cannula or humidifier.* 2. Inspect for kinks or blockages. Correct, clean or replace item. Once corrected, turn power Off for 60 seconds and then turn power back On.

3. Flowmeter set at 0.5 L/min or less.* 3. Check flowmeter is set to 1.0 L/min or more.

4. Unit overheating due to blocked air intake. 4a. Remove and clean cabinet filters. 4b. Move concentrator at least twelve inches from walls, draperies, and furniture.

5. Insufficient power at outlet. 5. DO NOT use extension cords. Move to another electrical outlet or circuit.
