The DSI control board is the central command module of the heating system — it sequences the inducer motor, spark igniter, gas valve, and flame sensing circuit to safely establish and sustain a burner flame. When this board fails, the most common symptoms include a no-heat condition, repeated ignition lockout, error codes on the unit's fault LED, or a furnace that sparks but never lights — or lights briefly and shuts back down within seconds.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Direct Spark Ignition (DSI) design | 24V control circuit | Integrated flame sense input | Factory-matched timing sequences for safe ignition and lockout reset | OEM part number LH33WP003\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM board, manufactured to exact factory timing and voltage specifications.
