The DSI control board is the brain of your unit's heating system — it sequences the entire ignition cycle, monitors safety inputs such as the pressure switch and high-limit, commands the gas valve, and drives the direct spark igniter. When this board fails, common symptoms include a hard lockout with no ignition attempt, intermittent no-heat calls, failure to prove flame, or the unit cycling on and off without ever completing a heat sequence. Replacing with a genuine OEM board ensures all timing parameters, safety thresholds, and fault-code logic exactly match factory specifications.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Direct Spark Ignition (DSI) control board | OEM Part No. LH33WP002 | 24V control circuit compatible | Factory-matched ignition timing and safety lockout logic for Carrier PY3PEA036060AB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e Genuine OEM boards carry factory-calibrated ignition timing and safety lockout sequences.
