blower keeps running


Hi, I am looking at an old carrier furnace that does not use an IDM.This unit relies on an vented draft when in use.Anyway when the furnace runs the cycle the burners cycle off twice and all is normal, but then if the unit comes on after that the burners go off and the blower keeps running and will not shut off(as if the board was looked out and bypassing the t stat).I replaced the limit and the control board but still same problem.The only thing i can think of is that the heat exchanger is corroded and getting to hot not allowing the vapors and excess heat escape.Can anyone who might have seen this before help me in my diagnosis? Thank you.
