The integrated furnace control board is the brain of the system — it sequences the inducer, igniter, gas valve, and blower, monitors safety limits and flame sense, and times each heating cycle. When the board fails, you typically see no response on a call for heat, erratic blower behavior, repeated lockouts, or fault codes flashing on the diagnostic LED. This kit is the complete factory replacement assembly for a direct, code-correct swap.
