Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

If the flames are clean and mostly blue then there's not enough air for combustion in the space. Your unit should have shut down on its own when this happens. It has an oxygen depletion sensor which apparently isn't working.

Makes sense. The system is the same as before the problem occurred??????
HVAC Technician: Rick, HVAC Supervisor replied 7 months ago

It's not the "system" it's the available air in the space.
