OEM Carrier Ignition Control Board LH33WP007 for Model PY3GNA048130NA

This is the factory OEM ignition control board (part number LH33WP007), the direct-replacement circuit board for the Carrier PY3GNA048130NA packaged gas/electric unit. The ignition control board is the central brain of the heating sequence — it manages the induced draft motor, hot surface igniter, gas valve, and flame sensor in precise coordination. When this board fails, common symptoms include a hard lockout with no heat output, repeated ignition attempts with no flame establishment, error codes flashing on the board's LED, or a system that powers on but never advances past the pre-purge stage.
