OEM Carrier Control Board LH33WP007 for Model PY4GPAA30060AA

This is the OEM factory-replacement integrated function control (IFC) board for the Carrier PY4GPAA30060AA packaged unit. The control board is the brain of your system — it sequences ignition, manages blower timing, monitors safety inputs (pressure switches, limit switches, flame sensor), and coordinates all heating and cooling functions. When the board fails, symptoms range from a completely unresponsive unit to intermittent fault lockouts, erratic blower behavior, no ignition attempt, or a system that runs one stage but not the other.
