OEM Carrier Integrated Control Board CESO110074-01 for Model GA1AAD036085ABJA

This is the factory OEM integrated furnace control (IFC) board for the Carrier GA1AAD036085ABJA gas furnace. The control board is the central brain of your heating system — it sequences every stage of furnace operation including inducer startup, hot surface ignition, gas valve activation, blower timing, and fault detection. When this board fails, you may experience a complete no-heat condition, repeated ignition lockouts, erratic blower behavior, or a system that powers on but never advances past a specific stage in the heating cycle. In many cases, the board's onboard diagnostic LED will flash a fault code that pinpoints the failure.
