The DSI control board serves as the brain of the heating system, orchestrating the complete ignition sequence — from inducer motor start and pressure switch verification through spark ignition, flame sensing, and burner steady-state operation. When this board fails, common symptoms include a complete no-heat condition, repeated ignition lockout faults, erratic burner cycling, or failure to advance past the inducer pre-purge stage. Replacing the board with an exact OEM unit restores factory-programmed timing and safety lockout logic.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Direct Spark Ignition (DSI) control board | OEM Part Number: \u003cstrong\u003eLH33WP002\u003c\/strong\u003e | Factory-matched control voltages and timing sequences | Compatible with 24V control circuit architecture standard to Carrier packaged units\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM boards carry factory-programmed ignition timing, precise lockout thresholds, and certified safety logic.
