OEM Carrier Control Board CESO130025-01 for Model FA4ANC042010AEAA Air Handler

This is the factory OEM replacement control board (part number CESO130025-01) for the Carrier FA4ANC042010AEAA air handler. The integrated function control (IFC) board serves as the central command module for your air handling unit — sequencing blower motor speeds, managing electric heat strips or auxiliary heat, interpreting thermostat signals, and providing fault protection and diagnostic LED codes. When this board fails, symptoms typically include the system failing to respond to thermostat calls, the blower running continuously or not at all, error codes flashing on the board, or the unit locking out entirely with no heating or cooling output.

• Specs: OEM part number CESO130025-01 | Factory-matched for Carrier FA4ANC042010AEAA air handler | 24V control circuit compatible | Multi-speed blower control with integrated fault diagnostics and LED indicator
• OEM vs Generic: This is a genuine Carrier OEM board — not an aftermarket substitute. OEM boards retain exact firmware, relay ratings, and terminal layouts, eliminating the risk of miswired aftermarket boards that can damage motors, transformers, or heat strips over time.
• Install difficulty: 3/5 — Requires safely disconnecting 240V power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, phone or camera to photograph all wiring harnesses prior to removal. Transfer all wiring connections one at a time to avoid errors. Recommend checking transformer output (24V) before replacing board to confirm board is the root cause.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our stocked warehouse when ordered before cutoff.

Compatibility: Designed and factory-spec'd for the Carrier FA4ANC042010AEAA residential air handler. Verify your existing board's part number on the board label before ordering. If your board shows burn marks or damaged relays, also inspect the transformer and blower motor for downstream damage prior to installation.
