OEM Carrier Direct Spark Ignition (DSI) Control Board LH33WP002 for Model PY2PEB036060AA

This is the factory OEM Direct Spark Ignition (DSI) control board for the Carrier PY2PEB036060AA packaged unit. The DSI control board serves as the operational brain of the heating system — it manages the ignition sequence, monitors the flame sensor signal, controls the inducer and gas valve, and handles fault lockout logic. When this board fails, symptoms typically include a no-heat condition, repeated ignition lockouts, an unresponsive system despite a call for heat, or erratic cycling that cannot be resolved by resetting the thermostat.
