Description
The Carrier CESO110057 02 is a factory authorized control board designed for many residential and light commercial furnaces from the Carrier, Bryant and Payne brands. It serves as the “brain” of the furnace — regulating key functions including ignition, inducer motor, blower motor timing, safety shut offs and diagnostic fault codes. This board replaces earlier models such as CESO110057, CESO110057 00, CESO110057 01, CESO110048 and CESO110020 — making it an efficient choice for upgrading, repairing or servicing compatible furnace systems.
Key Features
- OEM fit & quality: As a Factory Authorized Part™, the CESO110057 02 matches manufacturer specifications for dimensions, wiring harness placement and firmware logic — helping preserve system performance and reliability.
- Advanced diagnostics: Built in LED fault code indicators make it easier for technicians to identify issues such as pressure switch faults, inducer motor failures, flame sensing errors, and more — reducing diagnosis time and service visits.
- Improved safety and control: Includes features like full gas valve shut off in the event of ignition failure, reverse polarity protection, and brown out detection to safeguard both the furnace and the occupants.
- Wide application compatibility: Works with popular furnace model series (such as 349MAV / 373LAV / 376CAV / 383KAV / 395CAV / 398AAV / 399AAV) and many Carrier 58 series furnaces (58DHC, DXC, EJA, PAV, SSC, SXC, WAV, ZAV) — simplifying part inventory for service technicians.
- Drop in replacement: Since it supersedes multiple previous board part numbers, this board allows technicians to stock one high use part instead of several, reducing downtime and improving service efficiency.
