The DSI control board is the brain of the heating system — it sequences the inducer motor, spark igniter, gas valve, and flame verification in a precise timed cycle. When this board fails, common symptoms include a system that attempts ignition but locks out, a furnace that sparks repeatedly without lighting, error codes flashing on the board's LED indicator, or a complete loss of heat with no ignition attempt at all.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part Number LH33WP002 | Direct Spark Ignition (DSI) control | 24V control circuit compatible | Factory-programmed ignition timing and lockout logic matched to Carrier N6A48NG481451 specifications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the factory-original Carrier control board.
