OEM Carrier Ignition Control Board LH33WP007 for Model PY3GPAA48090NA
This OEM ignition control board (IGC board) is the factory-specified replacement for the Carrier PY3GPAA48090NA packaged gas/electric unit. The IGC board is the central brain of the heating system — it sequences the inducer motor, hot surface igniter, gas valve, and flame sensor through every call for heat. When this board fails, symptoms typically include a hard lockout with no ignition attempt, intermittent heating, fault codes on the LED indicator, or a furnace that starts briefly then shuts down on safety rollout.
