Carrier HK61EA006 Circuit Board

Integrate the Carrier HK61EA006 Circuit Board to restore precise timing and blower control within your residential or commercial fan coil and air handler units. This OEM control board is a high-reliability component designed specifically for Carrier and Bryant systems, featuring an integrated time delay relay that optimizes airflow by managing the fan motor’s post-purge cycle. By maintaining blower operation for approximately 90 seconds after the thermostat "G" signal ends, it effectively purges residual conditioned air from the ductwork, increasing overall system efficiency and contractor-grade performance.

The HK61EA006 is engineered for a direct-fit swap-out, replacing several legacy part numbers including HK61EA002, 1171734, and CEPL130541-01. As a factory-authorized part, it handles inductive loads across a wide temperature range of -40°C to 85°C. This surface-mount module includes diagnostic LEDs and a 5-amp low-voltage fuse to protect 24V control circuits, making it the standard choice for technicians servicing FA4C, FB4B, and FX4D fan coil platforms.

Key Benefits:

• Precise Fan Timing: Integrated 90-second delay relay ensures professional-level duct purging and improved occupant comfort.
• OEM Compatibility: Exact replacement for Carrier, Bryant, and Payne air handlers, eliminating the need for field modifications.
• Diagnostic Capabilities: On-board LEDs allow for rapid troubleshooting of power and signal faults in the field.
• Robust Circuit Protection: Features a replaceable 5A fuse to safeguard the board and transformer against low-voltage shorts.
• Wide Application: Serves as a direct supersedence for older control board iterations with identical mounting footprints.

Common Questions:

• Why is my blower fan running continuously? This often indicates a stuck relay on the control board or an incorrect thermostat fan setting. Check signals at the board before replacement.
• Is this board a direct replacement for HK61EA002? Yes, the HK61EA006 is the current factory-authorized successor for the HK61EA002 series.
• Does this board require a separate wiring harness? While it uses standard connections, verify if the existing harness is damaged, as the Carrier 327905-701 harness is sold separately.
