When it fails, common symptoms include a hard lockout after repeated ignition attempts, a fault code indicating no ignition, the system attempting to light but shutting down immediately, or a complete no-heat condition with no ignition sequence initiated at all.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Direct Spark Ignition (DSI) control | 460V application | OEM part number LH33WP002 | Replaces legacy revision LH33WP002A | Factory-matched timing sequences and lockout parameters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine Carrier-manufactured board — not an aftermarket substitute.
