York S1-031-09199-000 Thermistor Sensor

The York S1-031-09199-000 Thermistor Sensor is a precision-engineered 10k ohm NTC temperature sensor designed for accurate thermal feedback in York and Johnson Controls HVAC systems. This OEM heating and cooling replacement part provides critical resistance data to the control board to manage refrigerant flow, air delivery, and system cycling. Field technicians rely on this HVAC thermistor replacement for its specific resistance curve, ensuring that the control logic accurately reflects ambient or coil temperatures. Replacing a drifted or failed Johnson Controls temperature sensor with this genuine component eliminates diagnostic errors and prevents evaporator freeze-ups. As a vital York replacement part, it features durable lead wires and thermal-responsive casing suitable for high-vibration environments. Integrating this York air temperature sensor into your service routine ensures the system operates within manufacturer parameters, maintaining efficiency and preventing unnecessary component wear during extreme demand periods.

• 10K Ohm Resistance: Provides high-precision signal output compatible with standard York control boards.
• OEM Compatibility: Ensures a direct fit and immediate communication with existing system wire harnesses.
• Enhanced Durability: Engineered to withstand thermal cycling and moisture within air handlers and condensers.

How do I test the York S1-031-09199-000? Using a multimeter set to the ohm scale, verify the resistance against a standard 10k NTC chart; at 77°F (25°C), the sensor should read approximately 10,000 ohms.

Where is this sensor typically located? It is commonly mounted on the evaporator coil or in the return air stream to monitor air or refrigerant temperature for the primary controller.

What causes this thermistor to fail? Most failures result from moisture intrusion or lead wire corrosion, leading to skewed resistance readings and incorrect system cycling.
