OEM Carrier Direct Spark Ignition (DSI) Control Board LH33WP002 for Model PY3PEA060130AB

This is the genuine OEM Direct Spark Ignition (DSI) control board for the Carrier PY3PEA060130AB packaged gas/electric unit. The DSI control board serves as the nerve center of the heating system — it sequences the inducer motor, manages spark ignition timing, monitors the flame sensor signal, and governs safety lockout protocols. When this board fails, common symptoms include a complete no-heat condition, repeated ignition lockouts, failure to fire after the inducer proves, or erratic burner cycling that does not resolve with a reset. Replacing it with a genuine OEM board ensures factory-precise timing and lockout logic, protecting the heat exchanger and gas valve from unsafe operating conditions.

• Part Number: LH33WP002 (supersedes LH33WP002A) | Direct Spark Ignition (DSI) control board | 460V application | Factory-matched ignition timing and flame-sensing thresholds
• OEM vs Generic: OEM DSI boards use factory-calibrated spark timing and flame rectification sensitivity. Aftermarket alternatives frequently ship with mismatched lockout delay timing, which can allow raw gas accumulation or generate nuisance lockouts — OEM is strongly recommended for this safety-critical component.
• Install Difficulty: 4/5 — Requires isolation of 460V power supply before any work begins. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, and a phone camera to document all low-voltage wire connections prior to removal. Always verify the inducer, pressure switch, and flame sensor are functional before condemning the board.
• Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.
