OEM Carrier Fan Blower Control Board HK61EA006 for Model FC4CNF024000AAAA

This is the factory OEM fan blower control board (part number HK61EA006) for the Carrier FC4CNF024000AAAA fan coil air handler. The control board serves as the central command module for all blower and fan operations — managing motor speed sequencing, demand signals from the thermostat, and safety circuit monitoring. When this board fails, common symptoms include the blower failing to start, the fan running continuously regardless of thermostat demand, erratic multi-speed operation, or the system going into lockout with no obvious mechanical cause. Replacing this board with the factory-specified OEM part ensures full compatibility with Carrier's proprietary motor control logic and safety features.

• Specs: OEM Part No. HK61EA006 | Factory-matched control logic for FC4CNF024000AAAA | Compatible with 24V control circuit | Supports multi-speed ECM/PSC blower motor sequencing
• OEM vs Generic: OEM control boards carry factory-programmed firmware and exact terminal layouts. Generic or remanufactured boards frequently ship with mismatched timing delays and non-original connectors, leading to callback visits and potential motor damage over time.
• Install difficulty: 3/5 — Shut off all power at the breaker and confirm zero voltage with a multimeter before proceeding. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, phone or camera to photograph all wiring before disconnection. Transfer one wire at a time to avoid miswiring. Allow 5 minutes after power-down for capacitors to discharge.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Ships same business day from our climate-controlled warehouse in original manufacturer packaging.
