OEM Carrier Control Board CESO110074-01 for Model GA2AAD024055AAJA

This is the factory OEM integrated furnace control (IFC) board, part number CESO110074-01, designed as the direct replacement for the Carrier GA2AAD024055AAJA gas furnace. The control board serves as the central command center for your heating system — it sequences the inducer motor, hot surface igniter, gas valve, and blower fan in precise timing to ensure safe, efficient operation. When the control board fails, symptoms typically include complete system lockout, error codes flashing on the board's diagnostic LED, intermittent ignition failure, improper blower timing, or a furnace that powers on but refuses to fire or complete a heat cycle.

• Specs: OEM part number CESO110074-01 | Factory-matched circuitry for Carrier GA2AAD024055AAJA | 24V control circuit compatible | Integrated diagnostic LED fault codes for simplified troubleshooting
• OEM vs Generic: This is a genuine Carrier OEM board — not an aftermarket substitute. Generic control boards often lack exact firmware timing sequences and terminal configurations, leading to nuisance lockouts, unsafe ignition sequencing, or premature component failure. OEM guarantees a drop-in fit with zero guesswork.
• Install Difficulty: 3/5 — Disconnect power and gas before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, phone or camera to photograph all wiring harness connections before removal. Label each connector; the board has multiple identical-looking plugs. Allow 45–75 minutes for a careful swap.
• Warranty: 1-year OEM manufacturer warranty against defects. Orders placed before cutoff ship same business day from our climate-controlled warehouse.
