As the central intelligence of the heating system, this board manages the complete ignition sequence — energizing the inducer motor, proving pressure switches, firing the direct spark igniter, and monitoring the flame signal. When this board fails, you'll typically experience a hard lockout with no ignition attempt, intermittent no-heat calls, erratic burner cycling, or a system that sparks but never lights and then locks out after repeated trials.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Direct Spark Ignition (DSI) control | 460V application | Replaces legacy part LH33WP002A | Manages multi-stage ignition sequence, inducer prove, and flame supervision\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM board — not a third-party clone.
