OEM Carrier Fan Blower Control Board HK61EA002 for Model FA4ANF030010AFAA

This is the OEM factory-specified fan blower control board (part number HK61EA002) for the Carrier FA4ANF030010AFAA air handler. The blower control board serves as the command center for your air handler's indoor fan operation — managing blower motor speed, timing sequences, and communication with the thermostat and outdoor unit. When this board fails, common symptoms include the blower motor not starting, continuous or erratic fan operation, failure to respond to thermostat calls, or a complete system lockout with no heating or cooling airflow delivered to the living space.

• Specs: OEM Part Number HK61EA002 | Factory-matched control logic for FA4ANF030010AFAA air handler | 24V control circuit compatible | Designed for multi-speed blower motor operation
• OEM vs Generic: This is a genuine Carrier OEM board with factory-programmed timing and speed profiles specific to the FA4ANF030010AFAA. Aftermarket boards may use generic firmware that mismatches blower ramp-up timing and communicating thermostat protocols, leading to reduced comfort, efficiency, and potential motor damage over time.
• Install difficulty: 3/5 — Requires disconnecting 120V and 24V wiring harnesses and documenting all connector positions before removal. Tools needed: Phillips and flathead screwdrivers, needle-nose pliers, smartphone (to photograph wiring), and a multimeter to confirm 24V supply is present. Always shut off power at the disconnect and breaker before servicing. If the unit is connected to a communicating thermostat system, verify board compatibility before powering on.
• Warranty: 1-year OEM factory warranty against defects. Orders placed by 3PM local time ship same business day from our climate-controlled parts warehouse.
