York S1-025-32701-000 Temperature Sensor

The York S1-025-32701-000 Temperature Sensor is a critical diagnostic and operational component for York, Luxaire, and Coleman condensing units. This ambient air temperature sensor utilizes a high-precision NTC thermistor to provide real-time atmospheric data to the primary control board. For technicians servicing heat pumps, the 025-32701-000 is essential for managing defrost cycles and outdoor fan staging based on actual environmental conditions. Precise resistance values ensure the system logic avoids unnecessary short-cycling or incorrect delta-T calculations. This OEM York replacement sensor features heavy-duty lead wires and a moisture-resistant encapsulation designed to withstand the thermal expansion and contraction cycles common in outdoor HVACR environments. Replacing a drifted or failed HVAC ambient sensor with this genuine Source 1 part restores the factory-specified operational curve, ensuring the equipment maintains high-efficiency performance and accurate temperature sensing across its entire rated range without the calibration errors seen in generic alternatives.

• Ensures accurate defrost initiation and termination for heat pump applications.
• Direct-fit York replacement part simplifies installation on the control board.
• Hardened thermistor element prevents temperature drift in extreme climates.
• Eliminating calibration offsets maintains the integrity of the system's energy efficiency ratings.

What are the symptoms of a failing S1-025-32701-000?
A failed sensor often results in incorrect defrost timing, outdoor fan failure to cycle, or system lockouts with fault codes indicating an open or shorted ambient sensor circuit.

Can this sensor be used for liquid line temperature measurements?
No, this specific part is calibrated for ambient air monitoring; liquid or suction line applications require sensors designed for surface contact or immersion with different thermal response rates.

Does this require special field calibration?
This is a plug-and-play component designed to match the factory resistance-to-temperature table programmed into the York control logic.
