OEM Carrier Direct Spark Ignition (DSI) Control Board LH33WP002 for Model PY3PEA060130AA

This is the factory OEM Direct Spark Ignition (DSI) control board for the Carrier PY3PEA060130AA packaged gas/electric unit. As the brain of the heating system, this board manages the complete ignition sequence — energizing the inducer motor, proving the pressure switch, firing the direct spark igniter, confirming flame, and modulating the gas valve. When this board fails, common symptoms include a hard lockout with no ignition attempt, intermittent no-heat calls, fault codes indicating ignition failure, or the system cycling on and off without ever establishing a flame. Replacing with the genuine OEM board ensures all timing sequences, fault diagnostics, and safety lockout logic match Carrier factory specifications exactly.

• Part Number: LH33WP002 (supersedes LH33WP002A) | 460V application | Direct Spark Ignition (DSI) architecture | Factory-matched control logic and safety timing
• OEM vs Generic: OEM Carrier boards use factory-calibrated ignition timing and proprietary fault-code logic. Aftermarket boards may use generic timing curves that cause nuisance lockouts, void equipment warranties, or fail to interoperate correctly with Carrier pressure switches and gas valves.
• Install Difficulty: 3/5 — Requires disconnecting low-voltage and line-voltage wiring harnesses and documenting all connector positions before removal. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, phone or camera for wiring photos, and a multimeter to verify 24V control circuit power. Always disconnect power at the disconnect box before beginning.
• Warranty: 1-year OEM manufacturer warranty. Ships same business day from our stocked warehouse — no backorder delays.
