The DSI control board is the operational brain of your unit's heating system — it sequences the inducer motor, manages direct spark ignition timing, monitors flame status, and enforces safety lockouts. Common failure symptoms include a complete no-heat condition, repeated ignition lockout fault codes, intermittent heating cycles, or the unit failing to respond to thermostat calls for heat. Replacing with the exact OEM board (part number \u003cstrong\u003eLH33WP003\u003c\/strong\u003e) ensures all timing sequences, fault detection thresholds, and safety logic match factory specifications precisely.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Direct Spark Ignition (DSI) control board | OEM Part Number: LH33WP003 | Factory-matched ignition timing and safety lockout logic | Compatible with 24V control circuit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier board, not a generic or aftermarket substitute.
