OEM Carrier Control Board CESO130025-01 for Air Handler Model FA4ANC042010AAAA

This is the genuine OEM Carrier control board (part number CESO130025-01), the factory-specified replacement for the Carrier FA4ANC042010AAAA fan coil air handler. The integrated function control (IFC) board serves as the central command module of your air handler — orchestrating blower motor operation, electric heat sequencing, thermostat signal interpretation, and system fault protection. When the control board fails, symptoms typically include complete system lockout, failure to respond to thermostat calls, erratic blower behavior, or persistent fault codes that cannot be cleared by a reset.

• Specs: OEM Part No. CESO130025-01 | Designed for Carrier FA4ANC042010AAAA fan coil air handler | 24V control circuit compatible | Governs multi-speed blower, auxiliary heat sequencing, and fault diagnostics
• OEM vs Generic: This is a genuine Carrier OEM board — pre-programmed with factory timing sequences, speed tap configurations, and fault logic specific to the FA4ANC042010AAAA platform. Aftermarket boards frequently require manual jumper configuration and may not replicate proprietary Carrier fault codes, leading to misdiagnosis and callbacks.
• Install Difficulty: 3/5 — Photograph all wiring harness connections and label terminals before removal. Requires a flat-head and Phillips screwdriver, needle-nose pliers, and a multimeter to verify 24V control voltage before and after installation. Disconnect power at the disconnect box and confirm zero voltage before handling the board.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock and ships same business day from our warehouse.
