OEM Carrier Fan Blower Control Board HK61EA002 for Model PF1MNA042000AAAA

This is the factory OEM fan blower control board for the Carrier PF1MNA042000AAAA air handler. The control board is the nerve center of your air handler — it orchestrates blower motor operation, fan speed sequencing, time-delay relay functions, and communication with your thermostat. When this board fails, common symptoms include the blower fan not starting, the fan running continuously regardless of thermostat commands, erratic or intermittent airflow, or the entire air handler going into lockout mode with no response to calls for heating or cooling.

• OEM Part Number: HK61EA002 | Replaces superseded part numbers CESO130003-01, CESO130003-00, and CESO130003 | Includes integrated time-delay relay | Factory-matched to Carrier air handler specifications
• OEM vs Generic: This is a genuine Carrier OEM board — not an aftermarket substitute. OEM boards retain exact firmware, relay timing, and connector pinout, ensuring seamless drop-in operation without requiring any wiring modifications or programming.
• Install Difficulty: 3/5 — Disconnect power to the air handler before beginning. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, phone/camera to photograph all wiring connections before removal. Transfer connectors one at a time to the new board to avoid miswiring. Restore power and test all operating modes (heat, cool, fan-only) after installation.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
