OEM Carrier Direct Spark Ignition (DSI) Control Board LH33WP002 for Model PY2PEB060090AA

This is the genuine OEM Direct Spark Ignition (DSI) Control Board for the Carrier PY2PEB060090AA packaged gas/electric unit. The DSI control board serves as the central command center for the entire heating sequence — it manages spark ignition timing, monitors the flame sensor signal, controls the inducer and blower motors, and sequences gas valve operation. When this board fails, you'll typically experience a hard lockout with no ignition attempt, intermittent no-heat calls, or a system that sparks but immediately shuts down without establishing a flame. Replacing it with the correct OEM part ensures factory-specified timing and full compatibility with all onboard safeties.
