OEM Carrier Fan Blower Control Board HK61EA006 for Model PF1MNB030010AAAA

This OEM fan blower control board (part number HK61EA006) is the factory-specified replacement for the Carrier PF1MNB030010AAAA air handler. The board serves as the central command hub for your blower system — managing fan speed sequencing, operating the built-in time delay relay, and coordinating signals between the thermostat and the air handler's blower motor. When this board fails, you may experience a blower that won't start, a fan that runs continuously after the thermostat shuts off, erratic speed behavior, or a system that enters lockout without an obvious cause.

• Specs: OEM Part # HK61EA006 | Cross-references: CEPL130541-01, CEBD430541-03A, 1171734, 103972, 122621 | Includes integrated time-delay relay (approx. 90-second post-cycle blower purge) | Compact form factor (~4.1″ × 4.2″ × 2.1″) for direct drop-in fit
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part engineered to exact factory tolerances. Generic aftermarket boards frequently use off-spec relay timings and inferior PCB materials, which can cause premature failure, nuisance lockouts, or void your system's remaining warranty.
• Install Difficulty: 3/5 — Disconnect all power (line voltage AND 24V control power) before beginning. Tools needed: 1/4″ and 5/16″ nut drivers, needle-nose pliers, smartphone (photograph all wiring harness connections before removal). Label each connector — improper reconnection can damage the new board instantly. Recommend verifying thermostat signal voltages before installing to rule out a shorted control wire as the root cause.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.
