Question about Heating & Cooling
From what you are saying, I would bet you have acrack in the heat exchanger.See if you can watch the burner when the fan comes on. You should see the flame blow out and either move away from the flame sensor or onto a a rollout switch. I'm afraid the only remedy is to replace the heat exchanger or the furnace, depending on the age of the furnace.
