OEM Carrier Direct Spark Ignition (DSI) Control Board LH33WP002 for Model CP48P248P203510CP

This is the factory OEM Direct Spark Ignition (DSI) control board for the Carrier CP48P248P203510CP packaged unit. The DSI control board serves as the brain of the heating system — it sequences the induced draft blower, manages ignition spark timing, monitors the flame sensor signal, and coordinates gas valve operation. When this board fails, you may experience a hard lockout with no ignition attempt, repeated failed ignition cycles, erratic flame sensing, or a complete loss of heating function with no fault codes displayed. Replacing this board with the genuine OEM part ensures factory-matched timing sequences and reliable operation.
