The DSI control board is the nerve center of the heating system — it sequences the inducer motor, manages spark ignition timing, monitors the flame sensor signal, and governs safety lockout logic. When this board fails, you'll typically experience a hard lockout with no ignition attempt, intermittent no-heat calls, or a system that sparks but never lights and shuts down on fault. Replacing with the correct OEM board restores factory ignition timing and safety thresholds precisely.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Direct Spark Ignition (DSI) type | 460V application | Replaces superseded part LH33WP002A | Factory-matched ignition timing and lockout logic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM control boards carry exact firmware and component tolerances engineered for your unit.
