York 031-01095-002 Micro Board

The York 031-01095-002 Micro Board is a critical microprocessor control assembly engineered for high-tonnage York chiller systems and industrial HVAC applications. This processor board, often identified as BRD-4901 or BRD-4904, functions as the central logic unit for managing complex operations including compressor staging, fan sequencing, and safety interlock monitoring. Built for long-term reliability in demanding environments, this York PCB provides the precise digital oversight necessary for maintaining tight temperature tolerances and system efficiency. As a genuine OEM replacement part, it ensures seamless integration with existing chiller electrical infrastructures without the need for field modifications to the mounting header. Note that this specific microprocessor circuit board is supplied without an EPROM; technical personnel must ensure the appropriate firmware is transferred or installed to match the specific chiller model and serial number requirements. This board is essential for restoring full diagnostic capabilities and operational control to York chilled water systems.

• Direct OEM Compatibility: Engineered as a drop-in replacement for York part number 031-01095-002, ensuring proper electrical and physical fit.
• Centralized Logic Control: Manages critical safety loops and operational sequences to prevent component damage and optimize performance.
• High-Level Diagnostics: Facilitates accurate system fault reporting and status monitoring for streamlined troubleshooting by field technicians.
