OEM Carrier Fan Blower Control Board HK61EA002 for Model FA4ANF018005AFAA

This is the OEM factory-specified fan blower control board (part number HK61EA002) for the Carrier FA4ANF018005AFAA air handler. The integrated fan control (IFC) board serves as the central command module for your air handler — managing blower motor speeds, coordinating with the thermostat's heating and cooling calls, controlling auxiliary heat sequencing, and monitoring safety inputs. When this board fails, common symptoms include the blower not starting, the fan running continuously regardless of thermostat commands, erratic multi-speed operation, or a complete system lockout with no response to thermostat input.

• Specs: OEM Part Number HK61EA002 | Designed for Carrier FA4ANF018005AFAA air handler | 24V control circuit input | Multi-speed blower motor control with heating, cooling, and continuous fan outputs | Factory-calibrated delay-on and delay-off timing for optimal comfort and efficiency
• OEM vs Generic: This is a genuine Carrier OEM board — not an aftermarket substitute. OEM boards use factory-programmed logic with exact timing sequences, motor ramp profiles, and safety thresholds. Generic boards often use generalized firmware that can cause comfort complaints, short cycling, or nuisance lockouts that are difficult to diagnose.
• Install difficulty: 3/5 — Power down and lock out the unit at the disconnect before beginning. Tools needed: 1/4" and 5/16" nut drivers, flathead screwdriver, needle-nose pliers, phone or camera for wiring photos. Photograph all harness connections before removal. Transfer wiring connector by connector to avoid miswiring. Restore power only after all connections are secure and the cabinet panel is in place.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our stocked warehouse — no waiting on special orders.

Compatibility: This board is engineered specifically for the Carrier FA4ANF018005AFAA fan coil air handler. Always verify the OEM part number HK61EA002 against your unit's wiring diagram label or existing board before ordering. If you have questions about fitment, our HVAC parts specialists are available to confirm compatibility before you purchase — no guesswork required.
