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:
