York S1-031-01252-000 Temp Sensor

The York S1-031-01252-000 Temp Sensor is a high-precision OEM replacement part designed for critical thermal monitoring in residential and light commercial HVAC systems. This HVAC discharge air sensor features 48-inch lead wires, providing the necessary length for flexible sensor placement within deep supply air plenums. As a high-accuracy thermistor replacement, this component communicates directly with the integrated control board to modulate heating and cooling stages, preventing rapid cycling and ensuring the unit maintains targeted discharge temperatures. The S1-031-01252-000 sensor is a standard requirement for technicians diagnosing airflow faults or temperature calibration issues in York-branded equipment. Its rugged construction ensures the York temperature probe resists vibration and thermal stress within high-velocity air streams. Properly installing this discharge air temperature sensor is essential for maintaining the system's design delta-T and protecting the heat exchanger and evaporator coil from operation outside of safe thermal limits.

Key Benefits

• Direct OEM compatibility ensures seamless integration with York, Luxaire, and Coleman control systems.
• Extended 48-inch leads simplify routing through cabinet transitions and internal baffles.
• Fast-response thermistor provides real-time data to the control logic for improved humidity and temperature regulation.
• Plug-and-play installation reduces field labor time and eliminates the need for splicing into legacy wiring harnesses.

Common Questions

How do I verify the accuracy of the S1-031-01252-000?
Disconnect the sensor and measure the resistance across the leads using a multimeter set to ohms. Compare the reading to the standard NTC resistance chart found in the technical service manual for your specific model.

Where is this sensor typically mounted?
This probe is usually installed in the supply air ductwork, approximately 18 to 24 inches above the heat exchanger or evaporator coil, to get a representative average of the discharge air temperature.
