The integrated fan control board serves as the central command center for your air handler — managing blower motor speeds, sequencing heating and cooling operations, coordinating with the thermostat, and protecting the system through built-in diagnostics. When this board fails, common symptoms include the blower motor refusing to run, erratic fan speeds, failure to respond to thermostat calls, repeated lockout codes, or a completely unresponsive air handler that shows no signs of life.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part Number HK61EA002 | Designed for Carrier FB4ASX070000AEAA air handler | Factory-matched control logic, relay ratings, and terminal layout | Includes diagnostic LED indicator for fault code readout\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier board — not an aftermarket substitute.
