This OEM Carrier control board (CESO110074) is the factory-original circuit board for the FB4ANA024010AAAA fan coil air handler. It manages blower motor operation, fan speed staging, and the communication path between your thermostat, indoor unit, and outdoor condenser. When the air handler fails to start, runs without stopping, or throws fault codes, a degraded control board is a common root cause. Installing the exact OEM board ensures proper voltage signaling and protects your system from intermittent faults. Designed specifically for the Carrier FB4ANA024010AAAA model, this is a direct factory replacement that drops into the existing mounting bracket and wiring harness. Installation is moderate in difficulty and is best handled by an HVAC professional, as it involves disconnecting line voltage and matching low-voltage terminals correctly. Always cut power at the breaker before servicing. Genuine Carrier parts carry the correct certifications and a guaranteed fit, unlike generic boards. Order before 3PM CST and your control board ships same-day, so your air handler is back online fast. In stock and ready to ship today.
