OEM Carrier Fan Blower Control Board HK61EA006 for Model PF1MNC018000AAAA

This OEM fan blower control board (part number HK61EA006) is the factory-specified replacement for the Carrier PF1MNC018000AAAA air handler. The integrated fan control (IFC) board serves as the central command hub for the air handler — orchestrating blower motor speeds, heat sequencing, fault detection, and communication with the thermostat. When this board fails, common symptoms include the blower running continuously or not at all, erratic fan speeds, failure to respond to thermostat calls, error code lockouts, or a complete loss of heating and cooling airflow.

• Specs: OEM Part No. HK61EA006 | Factory-matched for Carrier PF1MNC018000AAAA air handler | Controls multi-speed blower motor operation | Integrated diagnostic LED fault codes for faster troubleshooting
• OEM vs Generic: This is a genuine Carrier OEM board, programmed and tested to exact factory specifications. Aftermarket control boards frequently use generic firmware that mismatches blower speed profiles and heat timing delays, risking premature motor failure and voided equipment warranties.

Tools needed: Phillips and flathead screwdrivers, needle-nose pliers, multimeter, phone/camera for wiring photos. Label every connector before removal to ensure correct reinstallation.
