York S1-025-41274-000 Temperature Sensor

The York S1-025-41274-000 Temperature Sensor is a high-precision thermistor designed for critical thermal monitoring within commercial and industrial HVAC systems. As a genuine OEM replacement part, this sensor ensures the control board receives accurate resistance feedback, preventing the calibration drift that causes improper compressor staging or short-cycling. Engineered to withstand the vibration and moisture typical of air handlers and chiller cabinets, the HVAC thermistor probe maintains set-point stability even in high-demand environments. Using this York replacement temperature sensor allows technicians to restore system logic to factory specifications, ensuring the unit operates within its optimized cooling or heating parameters. Its durable housing and specific lead length are designed for direct integration with existing wiring harnesses, making it an essential component for any commercial chiller system maintenance or repair. By providing consistent voltage signals to the controller, this sensor helps prevent ice accumulation on coils and protects vital system components from thermal stress.

• Precision Thermal Response: High-accuracy NTC thermistor technology provides exact data to the control logic for stabilized operation.
• Direct OEM Compatibility: Eliminates the need for field modifications, ensuring a perfect fit and seamless integration with York control systems.
• Industrial-Grade Construction: Built to resist moisture ingress and thermal cycling fatigue in harsh mechanical environments.
• Optimized System Efficiency: Accurate sensing prevents unnecessary energy consumption by ensuring the unit only cycles when required by actual load conditions.

How do I verify if the sensor is faulty?
Disconnect the sensor and use a multimeter to measure the resistance. Compare the Ohms reading against the York temperature-resistance chart for the S1-025-41274-000 model to identify any significant deviations or open circuits.

Is this sensor compatible with non-York equipment?
While some sensors share similar resistance curves, this York HVAC sensor is specifically calibrated for Johnson Controls/York equipment to ensure the control board interprets the signal correctly.

Where is this sensor typically mounted?
This probe is frequently utilized for discharge air, return air, or liquid line temperature monitoring, depending on the specific configuration of the rooftop or chiller unit.
