York 025-41756-302 Pressure Transducer

The York 025-41756-302 Pressure Transducer is a critical OEM replacement part designed for high-accuracy suction pressure monitoring in industrial and commercial HVAC systems. This 400 PSI transducer is the direct replacement for 025-41756-102, ensuring seamless mechanical and electrical compatibility with York chiller controllers and rooftop units. Built with a robust stainless steel body, it converts refrigerant pressure into a linear 0-5V DC signal, allowing the microboard to calculate real-time evaporator superheat and system performance. Experienced technicians will recognize its standard three-wire configuration: red for 5V power, black for ground, and white/green for the signal output. Whether you are troubleshooting chiller evaporator pressure issues or performing a routine refrigerant sensor replacement, this 0-400 PSIG sensor provides the precision necessary to maintain optimal subcooling and cooling efficiency. Using a genuine Johnson Controls York part prevents the signal drift and corrosion common with generic alternatives, especially in high-vibration screw compressor environments.

• Direct OEM Compatibility: Engineered as the official successor to the 025-41756-102, eliminating mounting or terminal issues.
• Precision Signal Output: Delivers a linear 0.5V to 4.5V DC signal across the 0-400 PSI range for spot-on controller accuracy.
• Versatile Application: Suitable for a wide range of refrigerants and compatible with York Millennium, Ylaa, and Yvwh chiller series.
• Industrial Durability: Stainless steel construction handles the temperature fluctuations and pressure spikes typical of suction line applications.
• Simplified Diagnostics: Standardized voltage-to-pressure formulas allow for fast field verification with a standard multimeter.

How do I verify if the 025-41756-302 transducer is failing?
Technicians should check for 5V DC across the red and black wires. If the supply is stable, measure the signal wire (white/green) to ground. Use the formula: V = (Pressure PSIG x 0.01) + 0.5. If the calculated voltage deviates significantly from the actual gauge pressure, the sensor requires replacement.

Is this part compatible with my 025-41756-102 sensor?
Yes, the 025-41756-302 is the current manufacturing standard and direct OEM cross-reference for the 102 model. It fits the same port and utilizes the same wiring harness configuration.

Do I need to replace the wiring harness with the transducer?
While not always mandatory, it is highly recommended. Many "sensor failures" are actually caused by moisture ingress and terminal corrosion within the transducer plug. Inspect the pins for green oxidation during your service call.
