Can you give me the complete model number on the furnace?
The number on outside of furnace is just a series.
Actual model will be on a label on inside furnace panel just above burners.Remove panel to burner compartment and look inside. The model number will help me give accurate assistance for your specific unit.
Below is a link to a generic video showing where to find label with model number:
OK here is the problem I have with this. The most likely cause for the flame shutting off this quickly is a dirty or defective flame sensor.
The problem is you say you are getting an open limit error code.If there is an open limit the furnace should not allow the burners to ignite period
You may have a bad board. Do you have a meter to check the limit circuit?
Just come back to question when ready and we will figure this out
