OEM Carrier Fan Blower Control Board HK61EA006 for Model PF4MNA018T00AAAA

This is the OEM Carrier fan blower control board (part number HK61EA006), the factory-authorized replacement for the Carrier PF4MNA018T00AAAA air handler. The blower control board manages all blower motor functions — including multi-speed fan operation, time delay relay sequencing, and coordinated heating/cooling response signals from the thermostat. When this board fails, symptoms typically include the blower fan refusing to start, the fan running continuously regardless of thermostat demand, the system failing to respond to heating or cooling calls, or erratic short-cycling behavior.

• Part Number: HK61EA006 | Cross-references: CEPL130541-01, CEBD430541-03A, 1171734, 103972, 122621 | Includes integrated time delay relay | Factory-matched OEM specification
• OEM vs Generic: This is a genuine Carrier OEM board — not an aftermarket clone. OEM boards carry exact firmware logic, correct time delay relay calibration, and full terminal compatibility, eliminating the risk of mismatched logic sequencing or nuisance lockouts common with generic substitutes.
• Install Difficulty: 3/5 — Shut off all power at the breaker and disconnect panel before beginning. Photograph all wiring connections before removal. Tools needed: Phillips and flathead screwdrivers, needle-nose pliers, and a multimeter to verify 24V control signal at the board terminals post-install. Label each wire harness connector before unplugging.
• Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse when ordered before 3 PM local time.
