The DSI control board serves as the central command hub for the heating sequence — it manages spark ignition timing, monitors the flame sensor signal, controls the gas valve, and sequences the inducer and blower motors. When this board fails, the unit will typically enter a hard lockout, attempt ignition with no result, display fault codes, or produce no heat at all despite the thermostat calling for it.\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 | Supersedes LH33WP002A | Factory-matched logic and timing sequences for Carrier PY-series packaged units\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM board — not an aftermarket substitute.
