OEM Carrier Fan Blower Control Board HK61EA006 for Model PF1MNC042000AAAA

This is the genuine OEM Carrier fan blower control board (part number HK61EA006), the factory-specified replacement for the Carrier PF1MNC042000AAAA air handler. The board governs all blower fan timing and speed sequencing, including the built-in time delay relay that staggers fan start and stop relative to cooling or heating demand. When this board fails, symptoms include the blower running continuously even with the thermostat off, the fan failing to start at all, evaporator coil icing due to loss of airflow control, or erratic multi-speed operation. Replacing this board with the correct OEM part restores factory-programmed timing and eliminates intermittent callbacks.

• Part Number: HK61EA006 | Cross-references: CEPL130541-01, 1171734, 103972, 122621 | Includes integrated time delay relay circuit
• OEM vs Generic: This is a genuine Carrier factory part — not an aftermarket clone. OEM boards carry exact firmware logic, relay timing calibration, and connector pinouts matched to your unit. Third-party boards can introduce mis-timed blower cycles, voided equipment warranties, and repeat failures.

Tools needed: Phillips screwdriver, 1/4" nut driver, needle-nose pliers, phone camera for wiring reference. Recommend verifying 24V control voltage at board terminals after installation.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
