OEM Carrier Fan Blower Control Board HK61EA006 for Model FY4ANF042000AAAA

This is the factory OEM fan blower control board (part number HK61EA006), the direct replacement for the Carrier FY4ANF042000AAAA air handler. The blower control board acts as the command center for all fan and blower motor operations — it interprets thermostat signals, manages blower speed staging, and coordinates with safety circuits to deliver proper airflow across heating and cooling cycles. When this board fails, common symptoms include the blower motor not starting, the fan running continuously regardless of thermostat commands, erratic multi-speed operation, or the entire air handler going into lockout with no response to thermostat calls.

• Specs: OEM part number HK61EA006 | Factory-programmed for multi-speed ECM/PSC blower control | 24V control circuit input | Compatible with single-stage and two-stage system configurations | Includes all factory terminal designations pre-labeled
• OEM vs Generic: This is a genuine Carrier OEM board, factory-programmed with the exact timing delays, speed profiles, and fault detection logic required by the FY4ANF042000AAAA air handler. Aftermarket boards often use generic firmware that mismatches blower ramp timing, leading to comfort issues, increased motor wear, and potential warranty voids on connected equipment.
• Install Difficulty: 3/5 — Disconnect power at the breaker and verify zero voltage with a multimeter before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, phone or camera to photograph all wiring harness connections prior to removal. Transfer wiring harnesses one connector at a time to avoid miswiring. No soldering required.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our dedicated HVAC parts warehouse.
