The DSI control board is the operational brain of the heating system — it sequences the inducer motor, manages spark ignition timing, monitors the flame sensor signal, and controls the gas valve and blower outputs. When this board fails, common symptoms include a complete no-heat condition, repeated ignition lockouts, fault codes indicating ignition failure, short cycling after startup, or erratic blower behavior. Replacing it with the factory-correct OEM part ensures all safety lockout circuits, timing sequences, and diagnostic LED outputs perform exactly to Carrier's engineering specifications.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e LH33WP002 (also supersedes LH33WP-002) | Application: Direct Spark Ignition (DSI) | Voltage: 460V | Carrier OEM factory replacement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM boards ship pre-programmed with Carrier's exact ignition timing, blower delay profiles, and safety lockout logic.
