OEM Carrier Ignition Control Board LH33WP007 for Model PY3GPAA36090NA

This OEM ignition control board (part number LH33WP007) is the factory-specified replacement for the Carrier PY3GPAA36090NA packaged gas unit. The ignition control board is the command center of the heating circuit — it sequences the inducer motor, monitors the pressure switch, energizes the hot surface igniter, opens the gas valve, and continuously monitors the flame sensor signal throughout every heating cycle. When this board fails, symptoms typically include a complete no-heat lockout, repeated ignition attempts with no flame establishment, erratic LED fault codes on the board itself, or a system that starts then shuts down within the first 30 seconds of the heating cycle.
