OEM Carrier Fan Blower Control Board HK61EA010 for Model FC4DNF024010AAAA

This is the factory OEM fan blower control board (part number HK61EA010) for the Carrier FC4DNF024010AAAA air handler. The blower control board serves as the central command module for the air handler, managing blower motor speed, fan delay timing, and communicating with the thermostat and system controls. When this board fails, common symptoms include a blower motor that won't start, a fan running continuously regardless of thermostat commands, erratic multi-speed operation, or a complete system lockout with no response to thermostat calls. Replacing with the correct OEM board ensures all factory timing sequences and motor control signals are restored precisely as engineered.
