OEM Carrier Fan Blower Control Board HK61EA006 for Model FY4ANF030000AAAA

This is the genuine OEM fan blower control board (part number HK61EA006), the factory-specified replacement for the Carrier FY4ANF030000AAAA fan coil air handler. The control board serves as the central command module for blower motor operation — it receives signals from the thermostat, sequences blower speeds, manages indoor fan timing, and protects the system through fault detection. When this board fails, you may experience a blower that won't start, a fan running continuously regardless of thermostat commands, erratic multi-speed operation, or a complete system lockout with no response to thermostat calls.

• Specs: OEM part number HK61EA006 | Factory-matched control logic for multi-speed ECM/PSC blower sequencing | 24V control circuit input | Designed for R-410A fan coil application | Includes integrated fault diagnostics
• OEM vs Generic: OEM control boards use factory-programmed logic chips calibrated to the exact blower motor profiles and timing delays of the FY4ANF030000AAAA. Aftermarket boards may use generic firmware that causes nuisance lockouts, incorrect fan speeds, or reduced system efficiency — risking compressor damage from improper airflow staging.
• Install Difficulty: 3/5 — Disconnect power at the breaker before beginning. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, phone or camera to photograph all wiring harness connections before removal. Label each connector carefully. Control boards involve multiple low-voltage connectors; take your time and verify each connection matches the original layout before restoring power.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our climate-controlled parts warehouse.
