The control board is the brain of your air handler — it sequences blower motor operation, manages multi-speed fan settings, monitors safety inputs, and communicates with the thermostat to deliver precise heating and cooling airflow. When this board fails, common symptoms include the blower not running at all, the fan running continuously regardless of thermostat demand, erratic speed behavior, system lockout codes, or complete loss of function in the air handler.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part No. HK61EA006 | 24V control circuit compatible | Multi-speed blower sequencing | Factory-programmed timing delays | Designed for Carrier FB4BSF018L00AAAA air handler\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the factory OEM board, not an aftermarket substitute.
