York 025-34177-000 Oil Temp Sensor

The York 025-34177-000 Oil Temp Sensor is a critical thermistor-based component designed for precise thermal monitoring within York HVAC systems and centrifugal chillers. Engineering specifications confirm this as a 10k Ohm NTC sensor (Negative Temperature Coefficient), calibrated to provide a standard resistance output of 10,000 Ohms at 77°F (25°C). This model is supplied without a well (w/o well), making it an ideal field replacement for integrated sensing ports where the original thermistor has drifted or failed.

Built for industrial durability, the 025-34177-000 ensures the control center receives accurate data to prevent compressor overheating and maintain viscosity within the lubrication circuit. It is compatible with a wide range of York applied systems and is often cross-referenced with part numbers such as SEN-4908 and 021004001900001. Utilizing an OEM York replacement part preserves the integrity of the diagnostic logic in your control panel, preventing the false "Low Oil Temperature" or "High Oil Temperature" trips common with off-brand thermistors.

• Precision Calibration: Maintains a strict 10k Ohm resistance @ 25°C to ensure accurate communication with York Millenium or OptiView control centers.
• Field Versatility: The without well configuration allows for direct insertion into existing thermowells, reducing labor time during maintenance.
• System Protection: Critical for monitoring compressor health, preventing expensive mechanical failures due to temperature-related oil breakdown.
• OEM Compatibility: Replaces York Part # 025-34177-000 and SEN-4908, ensuring the lead length and terminal connectors match the original equipment.

Is the thermowell included with this sensor?
No, this is the sensor probe only. It is designed to be installed into an existing well already present in the compressor or oil line.

Will this work with centrifugal chillers?
Yes, the 025-34177-000 is an official part for various York Applied Systems, including many centrifugal and screw chiller models using standard 10k Ohm inputs.

How can I test if my current sensor is bad?
Disconnect the sensor and measure the resistance with a multimeter. At room temperature (approx. 77°F), you should see a reading close to 10k Ohms. If it is open or shorted, it requires immediate replacement.
