I think it might need a thermocouple. I have a pilot light, the blower works, just no heat. Can I do this without blowing up my house??? I have no idea where to start. Or should I just call someone?
If you have a pilot the problem is not the thermocouple. From what you describe I'd say It's an electrical component of the furnace (in the brain box) that commands gas to the burner. Of course that's based on limited information and there are several components in this box that control the gas flow to the burner.

If you have no clue call someone and hope for the best.
