OEM Carrier Direct Spark Ignition (DSI) Control Board LH33WP002 for Model PY1PEA060080ADBA

This is the genuine OEM Carrier Direct Spark Ignition (DSI) Control Board, part number LH33WP002, factory-specified for the Carrier PY1PEA060080ADBA packaged unit. The DSI control board serves as the brain of the heating system — it sequences the inducer motor, spark ignition, gas valve, and flame verification in precise coordination. When this board fails, the system may enter a hard lockout, fail to initiate ignition, produce intermittent no-heat calls, or display fault codes indicating ignition or flame sense errors. A faulty board is one of the leading causes of a furnace that attempts ignition but shuts down immediately or never lights at all.
