Description
The York S1-031-00652-000 is an OEM-grade electronic control board designed to manage 2-stage cooling functions in compatible HVAC air conditioners or heat-pump systems. As the “brain” of the unit, it coordinates compressor operation, fan controls, and cooling stages to ensure efficient temperature regulation and energy-efficient operation under varying cooling loads.
Key Features
- 2-Stage Cooling Control — Enables smooth switching between low and high cooling stages for improved efficiency, quieter operation at low demand, and full cooling capacity when needed.
- OEM-Certified Board — Manufactured for York systems, ensuring proper fit, correct wiring interfaces, and reliable performance in units originally equipped for this board.
- Controls Compressor & Fan Operations — Manages timing, compressor cycling, and fan speeds to optimize comfort, reduce wear, and prevent short-cycling or overuse.
- Improves Efficiency & Longevity — By controlling stage transitions properly, it helps HVAC systems run more efficiently, reducing energy usage and stress on mechanical components over time.
- Direct Replacement for Obsolete Boards — Often sold as a replacement for legacy boards in older York, Coleman, or Luxaire systems — making upgrades or repairs simpler and helping extend the usable life of existing HVAC units.
