The DSI control board serves as the command center for the entire heating sequence — managing ignition timing, gas valve operation, flame sensing, inducer control, and safety lockout logic. When this board fails, symptoms typically include a no-heat condition, repeated ignition lockout codes, erratic cycling, or a furnace that sparks but never sustains a flame. Replacing with the correct OEM board (part number \u003cstrong\u003eLH33WP002\u003c\/strong\u003e) ensures all factory sequences, timing parameters, and safety thresholds are preserved exactly as designed.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number \u0026amp; Type:\u003c\/strong\u003e LH33WP002 | Direct Spark Ignition (DSI) Control Board | 460V ignition control module | Factory-original Carrier OEM specification\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM control boards carry the exact firmware, timing sequences, and safety logic programmed for your specific unit.
