York S1-031-01232-700 Temperature Sensor

The York S1-031-01232-700 Temperature Sensor is a precision 10k ohm thermistor designed for high-accuracy thermal feedback in residential and light commercial York HVAC equipment. Featuring 50-inch leads, this sensor offers the wire length necessary for flexible routing to control boards or terminal blocks in larger package units and split systems. It is commonly utilized as an ambient air sensor or discharge air temperature sensor to ensure the system is operating within proper thermal parameters. For technicians troubleshooting York Smart Equipment boards, a failing 1031-01232-700 typically triggers out-of-range faults or causes the system to lock out the heat/cool calls based on erroneous resistance readings.

Key Benefits:

• Genuine OEM replacement part ensures exact thermistor resistance-to-temperature calibration.
• Extended 50" lead length facilitates installation in diverse evaporator and condenser locations without splicing.
• Moisture-resistant construction reduces the risk of shorting in high-humidity or outdoor environments.
• Direct compatibility with several York, Johnson Controls, and Source 1 control systems for seamless thermostat communication.
• Crucial for preventing freeze-up conditions or high-pressure trip scenarios caused by inaccurate temperature data.

Common Questions:

How do I test if my York temperature sensor is bad?
Disconnect the sensor and use a multimeter to measure the resistance in ohms. Compare your reading against a standard 10k type 3 thermistor chart based on the current ambient temperature. If the resistance is zero (shorted) or infinite (open), the sensor requires replacement.

Can I use this sensor as an outdoor ambient or suction line sensor?
Yes, the S1-031-01232-700 is versatile and often serves as both an outdoor air temperature sensor (OAT) and a coil temperature sensor, depending on the specific model requirements of your York unit. Verify the lead length and terminal connector before installation.

Why is my York control board showing "Sensor Out of Range"?
This fault usually indicates that the temperature sensor is no longer providing a signal that aligns with its calibrated range. This can be caused by internal corrosion, wire damage, or moisture penetration in the sensor bulb.
