OEM Carrier Fan Blower Control Board HK61EA006 for Model FX4CSX024L00AAAA

This is the factory OEM fan blower control board (part number HK61EA006) for the Carrier FX4CSX024L00AAAA air handler. The control board serves as the brain of your air handler's blower assembly, managing fan speed staging, communicating with the thermostat, and coordinating heating and cooling calls. When this board fails, you may experience a blower motor that won't start, a fan that runs continuously regardless of thermostat commands, erratic multi-speed operation, or a complete system lockout with no response to thermostat signals.

• Specs: OEM part number HK61EA006 | Factory-matched for Carrier FX4CSX024L00AAAA air handler | 24V control circuit compatible | Supports multi-speed PSC blower motor operation | Includes integrated fault protection and LED diagnostics
• OEM vs Generic: This is the genuine Carrier OEM board — not a third-party clone. OEM boards are programmed to factory specifications with exact timing sequences, voltage thresholds, and fault logic. Aftermarket boards frequently use generic firmware that can cause nuisance lockouts, incorrect fan speed staging, and premature motor failure.
• Install difficulty: 3/5 — Intermediate DIY or professional recommended. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter, camera or phone to photograph all wiring connections before removal. Always shut off power at the disconnect and verify zero voltage with a multimeter before touching any terminals. Transfer wiring harnesses one connector at a time to avoid misrouting.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock and ships same business day from our climate-controlled parts warehouse.
