OEM Carrier Fan Blower Control Board HK61EA010 for Model FX4CNF024000AAAA

This is the genuine OEM fan blower control board (part number HK61EA010), the factory-specified replacement for the Carrier FX4CNF024000AAAA fan coil air handler. The control board serves as the brain of your air handler, orchestrating blower motor operation, fan speed sequencing, and communication with the thermostat and connected outdoor unit. When this board fails, common symptoms include the blower not starting at all, the fan running continuously regardless of thermostat commands, erratic speed changes, error codes on your thermostat, or complete system lockout with no heating or cooling delivered to the home.

• Specs: OEM part number HK61EA010 | Factory-matched control logic for FX4CNF024000AAAA fan coil | 24V control circuit input | Compatible with single-stage cooling operation | Direct plug-and-play board swap with original wiring harness connectors
• OEM vs Generic: This is a genuine Carrier OEM board — not a third-party clone. Aftermarket control boards frequently use off-tolerance components that cause intermittent faults, incorrect fan speed staging, or premature failure. The OEM board ensures exact compatibility with Carrier's communication protocols and safety logic built into the FX4CNF024000AAAA platform.
• Install difficulty: 3/5 — Power down the air handler at the disconnect and breaker before beginning. Tools needed: Phillips and flathead screwdrivers, needle-nose pliers, phone or camera to photograph all wiring connections before removal. Label every wire terminal. Take note of any DIP switch settings on the original board and replicate them exactly on the replacement. If unsure, a licensed HVAC technician is recommended.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock and ships same business day from our warehouse.
