OEM Carrier Fan Blower Control Board HK61EA006 for Model FY4ANF030010AAAA

This is the factory OEM fan blower control board (part number HK61EA006), the direct replacement for the Carrier FY4ANF030010AAAA fan coil air handler. The control board acts as the central command module for the blower assembly — managing fan speed staging, low-voltage thermostat signals, and indoor blower motor operation. When this board fails, common symptoms include a blower that won't start, erratic or continuous fan operation, failure to respond to thermostat commands, or a complete system lockout with no heating or cooling airflow.

• Specs: OEM part number HK61EA006 | Designed for Carrier FY4ANF030010AAAA fan coil air handler | 24V control circuit interface | Multi-speed blower motor outputs | Factory-programmed timing sequences for accurate staging
• OEM vs Generic: This is a genuine Carrier OEM control board with factory-programmed logic, correct connector pinouts, and matched timing delays. Aftermarket boards may require manual DIP-switch configuration and often lack model-specific fault diagnostics, risking blower damage or mismatched airflow profiles.
• Install Difficulty: 3/5 — Turn off all power at the breaker and air handler disconnect before beginning. Tools needed: Phillips and flat-head screwdrivers, needle-nose pliers, phone or camera to photograph all wiring harness connections before removal. Transfer wiring harnesses one-at-a-time to the new board to prevent miswiring. Verify all connectors are fully seated before restoring power.
• Warranty: 1-year OEM manufacturer warranty. Orders placed before cutoff ship the same business day from our warehouse.
