This authentic OEM Carrier control board is the direct factory replacement for the FB4ASB060000AGAA fan coil air handler. The control board acts as the brain of your air handler, managing blower-motor operation, relay timing, fan-speed selection, and integrated safety functions for efficient, reliable performance. Telltale signs of a failing board include a blower that won't start, erratic fan cycling, no response to thermostat calls, or repeated safety lockouts. Installing the correct factory-matched board restores proper communication between your thermostat, indoor blower, and outdoor unit so everything operates as designed. Since the repair involves wiring terminals and verifying configuration settings, we strongly recommend a licensed HVAC technician handle the installation to ensure correct setup and warranty compliance. Each board ships brand-new, carefully inspected, and built to Carrier's exact original specifications for lasting dependability. We keep this control board in stock and ship same-day on orders placed before 3PM CST. Choose NationalHVACParts.com for genuine Carrier parts and knowledgeable support.
