The DSI control board is the nerve center of your system's ignition sequence — it manages spark timing, proves flame via the flame sensor circuit, controls inducer and blower motor staging, and monitors safety switches throughout every heating cycle. When this board fails, you'll typically experience a hard lockout with no ignition attempt, intermittent no-heat calls, or the system sparking but failing to sustain a flame and locking out after 3 retries.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e LH33WP002 | Supersedes: LH33WP002A | Also referenced as: 1068-12, 1068-83-129A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier factory-authorized DSI board with factory-calibrated spark timing and flame-sense sensitivity thresholds.
