The DSI control board is the brain of the heating system — it sequences the ignition process by controlling the inducer motor, spark igniter, gas valve, and flame verification circuit. When this board fails, you may experience a hard lockout with no ignition attempt, intermittent no-heat calls, failure to prove flame, or a system that sparks but never opens the gas valve. Replacing the board with the correct OEM part restores factory-precise timing and sequencing logic.\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 | Factory-matched timing sequences for inducer pre-purge, spark, and flame hold — exact fit for Carrier CP48P348P303010CP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM boards use factory-programmed microcontrollers with correct lockout timing, fault codes, and safety thresholds.
