The DSI control board is the central command module that manages the entire heating sequence — from inducer motor startup and pressure switch verification through spark ignition, flame sensing, and burner operation. When this board fails, common symptoms include a complete no-heat condition, repeated ignition lockout faults, failure to advance through the heating sequence, or erratic cycling that never reaches steady-state burner operation.\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 | Factory-programmed timing sequences and fault lockout logic matched to Carrier N6A48NG482011 specifications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM board ships pre-programmed with Carrier's exact ignition timing, retry logic, and safety lockout parameters.
