OEM Carrier Integrated Control Board CESO110074-01 for Model GA2AAD048090ABJA

This is the factory OEM integrated furnace control (IFC) board for the Carrier GA2AAD048090ABJA gas furnace. The control board is the central brain of your heating system — it sequences the inducer motor, igniter, gas valve, and blower in precise timed stages. When it fails, symptoms range from a complete no-heat condition and repeated ignition lockouts to erratic cycling, fault code flashes on the LED indicator, or a blower that runs continuously with no heat output. Replacing a failed board with an OEM-matched unit restores full factory-programmed timing and safety logic.

• Specs: OEM Part Number CESO110074-01 | Factory-programmed timing sequences | Integrated LED diagnostic fault code display | 24V control circuit compatible | Designed for Carrier GA2AAD048090ABJA 4-ton, 90,000 BTU gas furnace
• OEM vs Generic: OEM control boards carry the exact firmware and component ratings specified by Carrier engineering. Aftermarket boards may omit safety lockout logic or use lower-rated relays, risking premature failure and voiding equipment warranties.
• Install difficulty: 3/5 — Disconnect power and gas before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, phone or camera to photograph all wiring harness connections prior to removal. Transfer wiring harnesses one connector at a time to avoid mis-wiring. Clear all fault codes after installation and run a full heat cycle to verify operation.
• Warranty: 1-year OEM factory warranty against defects. In-stock units ship same business day when ordered before 3PM local time.
