OEM Carrier Direct Spark Ignition (DSI) Control Board LH33WP002 for Model PY3PEA060130NB

This is the genuine OEM Carrier LH33WP002 Direct Spark Ignition (DSI) Control Board, the factory-specified replacement for the Carrier PY3PEA060130NB packaged gas/electric unit. The DSI control board is the nerve center of your heating system — it sequences the inducer motor, spark ignition, gas valve, and flame verification on every call for heat. When this board fails, you'll typically see a hard lockout error code, repeated ignition attempts with no flame establishment, or a complete no-heat condition with no visible fault at the thermostat or gas supply.

• Part Number: LH33WP002 | Replaces: LH33WP002A | Application: 460V Direct Spark Ignition Control | Factory-matched firmware and timing sequences
• OEM vs Generic: OEM boards retain the exact ignition trial timing, lockout logic, and fault code diagnostics engineered by Carrier. Aftermarket boards often ship with generic timing that can cause nuisance lockouts, missed fault codes, or premature gas valve wear — avoid the comeback call.
• Install Difficulty: 3/5 — Disconnect power and gas before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, phone/camera for wiring documentation. Label all low-voltage wires before removing the old board. Verify 24V control circuit is intact before powering up.
• Warranty: 1-year OEM manufacturer warranty. Ships same business day from our stocked warehouse — no backorder delays.
