The DSI control board is the brain of the heating sequence — it orchestrates the ignition trial, monitors the flame sensor signal, manages the inducer and blower motor timing, and enforces safety lockouts. When this board fails, symptoms typically include a no-heat condition, a repeated ignition lockout error, the burner lighting briefly then shutting off, or completely erratic heating cycles that cannot be resolved by thermostat adjustments alone.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Direct Spark Ignition (DSI) board | OEM Part Number LH33WP003 | Factory-matched control logic for Carrier PY3PNA024060NA | 24V control circuit compatible | Integrated fault code diagnostics via LED indicator\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM board is programmed to exact Carrier factory timing parameters for ignition trial duration, inter-purge delays, and lockout sequences.
