OEM Carrier Fan Blower Control Board for Model FX4ANF036000AAAA

This is the factory OEM fan blower control board for the Carrier FX4ANF036000AAAA air handler. The integrated furnace control (IFC) board serves as the brain of your air handling system — orchestrating blower motor speeds, managing heating and cooling sequences, interpreting thermostat signals, and protecting the system through built-in safety logic. When this board fails, symptoms can include the blower running continuously, refusing to start, improper fan speeds across heating and cooling modes, or the entire air handler going unresponsive despite a functioning thermostat. OEM part numbers CESO130025-01 and HK61EA002 are exact factory replacements for this unit.

• Specs: Factory-matched multi-speed blower control | 24V control circuit compatible | Integrated fault code diagnostics via LED | Supports single-stage cooling and multi-speed heating sequences | Replaces OEM part numbers CESO130025-01 and HK61EA002
• OEM vs Generic: OEM control boards are programmed with the exact timing delays, blower speed profiles, and safety thresholds specified by Carrier for the FX4ANF036000AAAA. Aftermarket boards often require manual DIP-switch configuration and may not replicate factory fault protection, risking nuisance lockouts or reduced equipment longevity.
• Install Difficulty: 3/5 — Photograph all wiring harness connections before disconnecting. Power down and confirm zero voltage at the board before handling. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Transfer any DIP-switch settings from the original board before powering up. A basic understanding of low-voltage control wiring is strongly recommended.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship the same business day from our warehouse.
