The DSI control board serves as the command center for the entire ignition sequence — it monitors the inducer, sequences the gas valve, fires the spark igniter, and verifies flame establishment via the flame sensor circuit. When this board fails, symptoms typically include a complete no-heat condition, repeated ignition lockouts, error codes on the system board, or a furnace that sparks but refuses to light and shuts down after one or two failed ignition attempts. Replacing it with a genuine OEM board ensures factory-exact timing and safety logic are fully restored.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e LH33WP002 | Replaces: LH33WP002A | OEM Direct Spark Ignition (DSI) Control Board | 460V rated | Factory-matched relay ratings and timing sequences\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM board with factory-programmed ignition timing, safety lockout thresholds, and relay specifications.
