OEM Carrier Fan Blower Control Board HK61EA010 for Model PF4MNA037000AAAA

This OEM fan blower control board (part number HK61EA010) is the factory-specified replacement for the Carrier PF4MNA037000AAAA air handler. The control board is the brain of your air handling system — it continuously monitors sensors and safety inputs, then coordinates the blower motor, heating elements, and auxiliary functions. When it fails, symptoms typically include the blower not responding to thermostat calls, erratic fan speeds, no heating or cooling output, or the unit going into a continuous lockout condition with no apparent cause in other components.

• Part Number: HK61EA010 | Cross-references: CEPL130658-01, CEBD430658-02A, 1172975 | Factory Authorized Carrier part
• OEM vs Generic: OEM boards are programmed and tested to exact Carrier factory specifications, ensuring correct blower timing sequences, fault code diagnostics, and compatibility with the unit's sensors and safety switches. Generic boards may omit these calibrations, causing nuisance lockouts or premature failures.
• Install Difficulty: 3/5 — Power down and lock out the unit before starting. Tools needed: #2 Phillips screwdriver, 1/4" nut driver, needle-nose pliers, phone or camera to photograph all wiring harness connections. Transfer wiring harnesses one connector at a time to avoid mis-wiring. Note any DIP switch settings on the old board and replicate them exactly on the new one.
