The DSI control board is the brain of your system's ignition sequence — it manages spark timing, monitors flame signal, governs gas valve operation, and coordinates the inducer and blower motors. When this board fails, symptoms typically include a hard lockout with no ignition attempt, repeated ignition cycles without establishing flame, an absent or missing spark signal, or a furnace that runs but immediately shuts down on a safety fault. Replacing with the genuine OEM board ensures all timing parameters, fault codes, and safety lockout logic match factory specifications exactly.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e LH33WP002 (also supersedes LH33WP002A) | Application: Direct Spark Ignition (DSI) | Voltage: 460V | Genuine Carrier OEM replacement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e The OEM LH33WP002 board uses factory-calibrated spark timing and flame-sensing thresholds.
