The DSI control board serves as the central command module for the heating sequence — managing ignition timing, flame verification, gas valve activation, inducer operation, and safety lockout logic. When this board fails, common symptoms include a complete no-heat condition, repeated ignition lockouts, failure to energize the gas valve, or erratic cycling that no thermostat adjustment can resolve. Fault codes displayed on the board's LED indicator are your first diagnostic clue before ordering.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part Number \u003cstrong\u003eLH33WP002\u003c\/strong\u003e | Direct Spark Ignition (DSI) control board | 24V control circuit compatible | Factory-programmed timing and lockout sequences for Carrier N6A48NG480200\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier board pre-programmed with exact ignition timing delays, trial-for-ignition periods, and lockout thresholds.
