Clogged heat exchanger ?

I have a Goodman furnace and when it first lights everything works fine. When the furnace comes on the second time it acts as though the center heat exchanger is clogged and I get a flash back shutting off the rollover limits. I have tried blowing the center tube out. What do I need to do to correct this.
