OEM Carrier Direct Spark Ignition (DSI) Control Board LH33WP002 for Model CP48P248P207011CP

This is the factory OEM Direct Spark Ignition (DSI) control board for the Carrier CP48P248P207011CP packaged unit. The DSI control board serves as the brain of the heating system — it sequences the inducer motor, manages the spark ignition event, monitors flame signal, and coordinates safety lockout logic. When this board fails, common symptoms include a no-heat condition, repeated ignition lockouts, failure to initiate the spark sequence, or erratic furnace cycling that does not resolve with a simple reset.

• Specs: OEM Part Number LH33WP002 | Direct Spark Ignition (DSI) control board | 24V control circuit compatible | Factory-programmed timing and lockout logic matched to Carrier CP48P248P207011CP specifications
• OEM vs Generic: This is the genuine Carrier OEM board — not an aftermarket substitute. Generic control boards frequently carry mismatched timing sequences and non-factory lockout thresholds that can cause nuisance trips, voided equipment warranties, and accelerated wear on ignition components. Always install OEM on DSI boards to maintain factory safety certifications.
• Install difficulty: 3/5 — Disconnect power and gas before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, phone or camera to photograph all wiring harness connections prior to removal. DSI boards involve multiple low-voltage and line-voltage connections — label every connector before unplugging. If in doubt, consult a licensed HVAC technician.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock and ships same business day from our warehouse.
