OEM Carrier Fan Blower Control Board HK61EA002 for Model FA4ANF024005AGAA

This is the factory OEM fan blower control board (part number HK61EA002), the direct replacement for the Carrier FA4ANF024005AGAA air handler. The control board serves as the central command module for blower motor operation — managing fan speed sequencing, delay timing, and communication between the thermostat and the blower assembly. When this board fails, common symptoms include the blower fan not starting, running continuously regardless of thermostat demand, erratic or incorrect fan speed selection, or a complete system lockout with no response to thermostat signals.

• Specs: OEM part number HK61EA002 | Designed for Carrier FA4ANF024005AGAA air handler | Factory-programmed timing and speed logic | Direct plug-and-play wiring harness compatibility
• OEM vs Generic: This is a genuine Carrier OEM board, pre-programmed with exact factory timing delays, speed profiles, and fault detection logic. Aftermarket boards often require manual DIP switch configuration and may not replicate all proprietary Carrier control sequences, risking premature component failure or voided equipment warranties.
• Install difficulty: 3/5 — Disconnect power at the breaker and verify zero voltage before removing the old board. Tools needed: Phillips and flathead screwdrivers, needle-nose pliers, multimeter, phone or camera for wiring documentation. Photograph all harness connections before removal. Board mounts on standard standoffs — swap connectors one at a time to avoid miswiring.
