York 331-02496-101 Control Board

The York 331-02496-101 Control Board is a precision-engineered OEM replacement part designed for integration into York air handlers and furnaces. As a programmed control board, it serves as the central processing unit for your HVAC system, managing 24V signals to coordinate the sequence of operation between the thermostat, inducer motor, blower, and gas valve. This HVAC circuit board is crucial for technicians troubleshooting intermittent system failures or "no-heat" calls where the CPU fails to deliver voltage to secondary components. Built for panel mount installation, this integrated furnace control ensures stable communication across the 16-pin wiring harness, protecting sensitive ECM motors and multi-speed blowers from erratic cycles. When your diagnostics confirm line voltage is present but the secondary side lacks 24VAC output, this genuine Johnson Controls manufactured board provides the exact logic required to restore factory-spec performance and optimize system efficiency.

• Factory-Programmed Logic: Features pre-loaded York 331-02496-101 firmware to ensure immediate compatibility without field flashing.
• Universal 24V Compatibility: Designed to interface seamlessly with standard 24VAC HVAC transformers and safety limit strings.
• Multi-Component Management: Regulates the timing and power distribution for inducer fans, igniters, and PSC or ECM blower motors.
• Simplified Diagnostics: Includes onboard terminal labeling (R, W, Y, G, C) to expedite field testing with a standard digital multimeter.
• OEM Durability: Constructed with high-grade relays and solder joints to withstand the thermal stress common in furnace control cabinets.

Is the York 331-02496-101 a direct replacement for my older board?
Yes, as an OEM part, it is the direct replacement for specific York and Johnson Controls models. Always verify the part number on your existing board's sticker before ordering.

What are the signs that my current control board has failed?
Common indicators include the LED status light remaining off despite receiving 120V/24V power, burnt components or "fish" odors on the circuit, or the blower failing to engage after the inducer completes its cycle.

Does this board require specific programming in the field?
No, the 331-02496-101 is a programmed control board, meaning the logic for the sequence of operation is hard-coded at the factory for immediate "plug-and-play" installation by a qualified technician.
