OEM Carrier Fan Blower Control Board HK61EA006 for Model PF1MNC030005AAAA

This is the factory-authorized OEM fan blower control board for the Carrier PF1MNC030005AAAA air handler. The board orchestrates all blower motor operations — managing multi-speed fan switching, interpreting thermostat signals, and executing the built-in time delay relay sequence that keeps air circulating for a brief purge cycle after the thermostat call ends. When this board fails, common symptoms include the blower failing to start, the fan running continuously regardless of thermostat input, erratic speed selection, or a complete system lockout with no response to thermostat commands.
