Factory Authorized Parts™ HK61EA002 Fan Coil Control Board | 24V Air Handler Logic Module | OEM Blower & Accessory Controller

The Factory Authorized Parts™ HK61EA002 serves as the central "brain" of your indoor air handling unit, functioning as the primary command module for fan sequencing and auxiliary heat management. This OEM-focused fan coil control board is the specific hardware responsible for translating thermostat signals into mechanical action, managing blower motor speeds, and timing the engagement of electric heat strips. Specifically engineered for Carrier, Bryant, and Payne fan coil series, this board ensures the "body" of the air handler—including the blower and condensate sensors—operates in perfect harmony. Replacing a failed or shorted board with the HK61EA002 restores factory-spec climate control and ensures that vital safety delays are active to protect your heating elements from overheating.

Key Features

• Genuine OEM Fan Coil Logic: Specifically programmed to replace part number HK61EA002, maintaining the exact factory-standard blower time-delay profiles for cooling and heating modes.
• Multi-Speed Blower Management: Actively controls the fan relays to fix issues with blowers that fail to engage, get stuck on one speed, or won't shut off after a cycle.
• Integrated Accessory Support: Features dedicated terminals for humidifiers and electronic air cleaners, allowing the "brain" to activate indoor air quality components simultaneously with the fan.
• Advanced Safety Circuits: Continuously monitors for low-voltage fluctuations and works in tandem with condensate overflow switches to shut down the system before water damage occurs.
• Precision Electric Heat Sequencing: Manages the staging of electric heat strips to ensure gradual power draws and consistent discharge air temperatures.

🛠️ HVAC Depot Pro Tip

Take a Picture First: Before disconnecting the multi-colored thermostat wires or the high-voltage heater plugs, photograph the terminal strip. It is vital to ensure the "G" (Fan) and "W" (Heat) wires return to their specific OEM positions. Conduct a diagnostic check by inspecting the onboard 3A or 5A fuse (if applicable) on the old board; if it is blown, check your thermostat wiring for a "rub-out" or short to ground before installing the new HK61EA002 to prevent immediate damage to the new circuitry.
