OEM Carrier Direct Spark Ignition (DSI) Control Board LH33WP002 for Model PY1PEB036060ABAA

This is the genuine OEM Carrier Direct Spark Ignition (DSI) Control Board, part number LH33WP002, factory-specified for the Carrier PY1PEB036060ABAA packaged unit. The DSI control board is the operational brain of the heating system — it manages the entire ignition sequence, coordinating the spark igniter, gas valve, combustion blower, and indoor fan motor while continuously monitoring flame sensing and enforcing safety lockout timers. When this board fails, the most common symptoms include a complete no-heat condition, repeated ignition lockouts, burners that light briefly then immediately shut off, or erratic blower behavior that disrupts the entire heating cycle.

• OEM vs Generic: This genuine Carrier OEM board is factory-programmed with exact ignition timing, flame-sensing thresholds, and lockout sequences for the PY1PEB036060ABAA. Aftermarket boards often use generalized firmware that can cause nuisance lockouts, imprecise gas valve timing, or voided equipment warranties.
• Install Difficulty: 3/5 — Disconnect power and gas before beginning. Tools needed: Phillips and flathead screwdrivers, needle-nose pliers, phone or camera to photograph all wiring harness connections before removal. Label every connector. A multimeter is recommended for verifying 24V control circuit continuity post-install. Recommend a licensed HVAC technician for gas appliance repairs.
