OEM Carrier Integrated Furnace Control Board CESO110057-02 for Model GB3AAV024050ABJA

This is the factory OEM Integrated Furnace Control Board (IFC) for the Carrier GB3AAV024050ABJA gas furnace, sold under OEM part number CESO110057-02. The control board is the nerve center of your furnace — it sequences every stage of operation including inducer startup, igniter timing, gas valve activation, blower delays, and safety lockout logic. When it fails, symptoms range from a completely dead furnace to erratic behavior such as false lockouts, ignition that never fires, blower running continuously, or fault codes that don't clear even after reset.

• Specs: OEM part number CESO110057-02 | 24V control circuit compatible | Integrated diagnostic LED fault code display | Factory-matched relay ratings and timing sequences for GB3AAV024050ABJA
• OEM vs Generic: An OEM control board guarantees exact relay timing, safety threshold calibration, and terminal layout engineered specifically for your Carrier furnace. Generic aftermarket boards may use approximated timing delays and looser safety tolerances, increasing the risk of nuisance lockouts or, worse, undetected fault conditions.

Power down and confirm zero voltage at board terminals before handling. Transfer wiring connections one-by-one to avoid miswiring.
