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

Then look in blower compartment and see if we have a control board with a blinking light.If so tell me the pattern of that flash.That will indicate what is wrong and tell us where to start troubleshooting.
