Can you give me complete model from inside furnace in burner compartment so I can provide guidance with this specific unit.Model will be on a label just above burners on right or left inside panel
That appears to be model on the blend air, rather than the actual furnace mode.Is everything working now?
Excellent now tell me exactly what is happening at this point.
Is the exhaust blower staying on?
Do you see a legend chart on furnace that may indicate an error code by the number of flashes?
Do you hear any beeping from the blend air control?
Found this on the blend air. Also tell me if furnace itself seems to work ok.
Does the furnace itself seem to be working ok?
Most likely just an issue with the fresh air blend motor,If it does it again, make sure the little blend air motor runs and turns freely.
If you have further questions, please let me know.
