OEM Carrier Fan Blower Control Board HK61EA002 for Model PF1MNA036000AAAA

This is the factory OEM fan blower control board for the Carrier PF1MNA036000AAAA air handler. The control board acts as the operational brain of your air handler unit — it sequences blower motor operation, monitors safety inputs, manages time-delay fan logic, and coordinates the start/stop cycle of all connected components. When this board fails, symptoms typically include the blower fan not starting, the fan running continuously regardless of thermostat demand, erratic cycling, or a complete system lockout with no response to thermostat signals.
