As the brain of your heating system, the DSI control board manages the complete ignition sequence — from inducer motor startup and pressure switch verification through spark ignition, gas valve activation, and flame confirmation. When this board fails, common symptoms include a hard lockout with no ignition attempt, the system short-cycling immediately after startup, error codes indicating a failed ignition sequence, or complete loss of heating function with the cooling side still operational.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e LH33WP002 (supersedes LH33WP002A) | Application: Direct Spark Ignition (DSI) Control | Voltage: 460V | Genuine Carrier OEM component\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e Factory OEM boards are programmed with Carrier's exact timing sequences, lockout logic, and fault diagnostics.
