OEM Carrier Direct Spark Ignition (DSI) Control Board LH33WP002 for Model PY1PEA060100AEBA

This is the factory OEM Direct Spark Ignition (DSI) Control Board for the Carrier PY1PEA060100AEBA packaged unit. Part number LH33WP002 serves as the central command of the heating system, orchestrating the ignition sequence, monitoring flame presence, managing gas valve timing, and triggering safety lockouts when fault conditions are detected. When this board fails, symptoms typically include a no-heat condition, repeated ignition lockout codes, short-cycling, or the system failing to advance past the ignition trial stage. Replacing this board with an OEM unit restores exact factory timing and logic — no guesswork, no recalibration required.

• Part Specs: OEM Part # LH33WP002 | Replaces LH33WP002A | Direct Spark Ignition (DSI) type | 460V application | Factory-programmed ignition timing and lockout logic
• OEM vs Generic: This is a genuine Carrier OEM board, not an aftermarket substitute. OEM control boards maintain factory-calibrated ignition trial periods, flame-sensing thresholds, and fault code sequences. Aftermarket boards may introduce timing drift, incompatible lockout logic, or voided equipment warranties.
• Install Difficulty: 3/5 — Requires disconnecting 120V/24V wiring harnesses, labeling all connectors before removal, and confirming gas valve and igniter wiring matches the new board layout. Tools needed: Phillips and flathead screwdrivers, needle-nose pliers, phone or camera to document wiring, and a multimeter for circuit verification. Always shut off gas supply and disconnect power before beginning. If fault codes persist after replacement, check igniter resistance and flame sensor rod condition.
• Warranty: 1-year OEM manufacturer warranty. Ships same business day from our stocked warehouse. Free shipping included.
