The DSI control board serves as the brain of the heating system — sequencing the inducer motor, spark igniter, gas valve, and flame verification in precise timing. When this board fails, common symptoms include a complete no-heat condition, repeated ignition lockout (flashing fault codes), erratic burner cycling, or a system that sparks but never opens the gas valve. Diagnosing a failed DSI board early prevents secondary damage to the gas valve and heat exchanger.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part Number LH33WP002 | Direct Spark Ignition (DSI) control | 24V control circuit input | Factory-programmed timing sequences for ignition, trial, and lockout — no field calibration required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the factory-original Carrier board, identical to what shipped in your unit.
