As the central brain of the heating system, this board manages the complete ignition sequence — energizing the inducer motor, proving pressure switch closure, firing the direct spark igniter, confirming flame, and staging the gas valve. When this board fails, you'll typically see a hard lockout with no ignition attempt, repeated ignition failures, or the unit firing briefly then shutting down on a fault code. In multi-stage or commercial packaged units like the PY3PEA060090AB, a failed DSI board can completely disable the heating section while leaving cooling unaffected — a symptom that often points directly to this component.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Direct Spark Ignition (DSI) control | 460V application | Replaces superseded part LH33WP002A | Factory-matched timing sequences and lockout logic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e Genuine Carrier OEM boards carry exact factory-programmed ignition timing, lockout retry counts, and fault code logic.
