The DSI control board is the brain of your heating system — it sequences the inducer motor, manages spark ignition timing, monitors the flame sensor signal, and orchestrates all safety lockout logic. When this board fails, symptoms typically include a complete no-heat condition, repeated ignition lockouts, an inducer that runs but no spark is produced, or a system that attempts ignition and immediately faults out without establishing a flame.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Direct Spark Ignition (DSI) control board | 460V application | OEM part number LH33WP002 | Supersedes LH33WP002A | Factory-matched timing and lockout parameters 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.
