OEM Carrier Direct Spark Ignition (DSI) Control Board LH33WP002 for Model N6A48NG480213

This is the factory OEM Direct Spark Ignition (DSI) control board for the Carrier N6A48NG480213 packaged gas/electric unit. The DSI control board is the nerve center of your system's heating operation — it sequences the inducer motor, spark ignition, gas valve, and flame sensing circuit in precise timing. When this board fails, common symptoms include a complete no-heat condition, repeated ignition lockout faults, failure to initiate the inducer, or erratic cycling where the burners light briefly then shut down without establishing a stable flame. If your Carrier N6A48NG480213 is flashing a fault code or locking out on ignition attempts, this board is frequently the root cause.
