OEM Carrier Ignition Control Board LH33WP007 for Model PY3GPAA36060NA

This is the genuine OEM Carrier ignition control board (part number LH33WP007), the factory-specified replacement for the Carrier PY3GPAA36060NA packaged gas/electric unit. The ignition control board is the brain of your system's heating sequence — it manages spark or hot surface ignition timing, monitors the flame sensor signal, and coordinates the inducer, gas valve, and blower motor. When this board fails, common symptoms include a no-heat lockout condition, repeated ignition attempts without flame establishment, erratic blower behavior, or a furnace that starts briefly then shuts down on a safety fault.
