York S1-025-41266-000 Discharge Sensor

The York S1-025-41266-000 Discharge Sensor is a precision-engineered OEM replacement part designed for critical mixed air temperature monitoring in York commercial and residential HVAC systems. As a veteran-grade discharge air sensor, this component ensures that your rooftop units (RTU) and chillers maintain optimal setpoints by providing high-accuracy thermal feedback to the control board. For contractors managing York HVAC systems, using genuine York replacement sensors is non-negotiable for system communication and preventing the performance lag often associated with aftermarket alternatives.

This HVAC temperature sensor is explicitly compatible with York model 9RT1H542-1 and integrated into advanced system profiles like the BP150C00B4AAA3. By monitoring discharge air temperature, the S1-025-41266-000 protects the compressor from high-heat failure and prevents the evaporator coil from freezing during low-load conditions. Its compact design allows for streamlined installation in narrow plenums, ensuring consistent resistance-to-temperature (NTC) readings that are vital for energy-efficient HVAC performance and long-term equipment stability.

• Precision Thermal Data: Delivers accurate mixed air temperature readings to the main controller to ensure environmental stability.
• OEM Compatibility: Specifically engineered for York model 9RT1H542-1 and related RTU configurations, ensuring seamless signal integration.
• System Protection: Acts as a primary diagnostic lead to prevent overheating and maintain energy efficiency across the refrigeration circuit.
• Durable Construction: Built to withstand the high-cycle environments of commercial heating and cooling systems.

What is the primary function of the York S1-025-41266-000?
This sensor monitors the air temperature exiting the system to ensure the HVAC unit is operating within defined safety and performance parameters.

Will this sensor work with non-York systems?
No, this is a specialized OEM York discharge sensor calibrated for specific resistance curves used in Johnson Controls/York equipment, specifically model 9RT1H542-1.

How do I know if my current discharge sensor has failed?
Common signs include erratic temperature readings on the thermostat, the system cycling off prematurely, or fault codes related to discharge air temperature limits on the control board.
