The DSI control board serves as the brain of the heating system — it sequences the inducer motor, manages the spark ignition trial, monitors the flame sensor, and controls safety lockout logic. When this board fails, common symptoms include a no-heat condition, repeated ignition lockouts, failure to initiate a spark, or the system cycling off immediately after ignition. In many cases the board will flash a fault code indicating an ignition or proving failure before shutting down entirely.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 460V application | Direct Spark Ignition (DSI) control type | 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 engineered to exact factory specifications.
