The DSI control board serves as the brain of the heating system — it sequences the inducer motor, spark igniter, gas valve, and flame verification circuit in precise timed stages. When this board fails, common symptoms include a no-heat condition, repeated ignition lockout faults, failure to prove flame after a successful spark, or erratic cycling behavior that cannot be resolved by resetting the thermostat or checking the filter. Fault LED blink codes on the board itself will often confirm a control board failure versus a failed downstream component.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Direct Spark Ignition (DSI) control | OEM Part Number \u003cstrong\u003eLH33WP002\u003c\/strong\u003e | 24V control circuit compatible | Factory-programmed ignition timing and lockout logic pre-loaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier board with factory-calibrated ignition timing sequences, lockout retry parameters, and fault diagnostics.
