York 025-40273-007 Sensor

The York 025-40273-007 Sensor is a critical OEM replacement part engineered for precision fluid monitoring in commercial HVACR applications. This 3000 Ohm resistance sensor is specifically designed to provide high-accuracy data for leaving water temperature (LWT), a vital metric for maintaining optimal chiller performance and preventing evaporator freeze-up. Technical field experience confirms that this thermistor-type leaving H2O sensor integrates seamlessly with York chiller control centers, ensuring the microprocessor receives stable, real-time feedback for precise staging and capacity control. By eliminating signal drift common in universal alternatives, this chiller temperature sensor helps technicians maintain the exact setpoints required for high-efficiency system operation. Whether you are performing a routine overhaul or troubleshooting a diagnostic fault code related to water temperature out-of-range, installing this genuine York 025-40273-007 ensures the longevity of the heat exchanger and minimizes the risk of costly downtime due to inaccurate thermal data.

• Precision Thermal Monitoring: Designed with a 3000 Ohm curve to deliver accurate leaving water temperature readings for chiller protection.
• OEM Compatibility: Guaranteed fit for multiple York chiller models, including many YK and YT series centrifugal units.
• Advanced System Stabilization: Helps prevent hunting in expansion valves and compressor staging by providing a clean, noise-free signal to the control board.
• Durable Technical Construction: Built to withstand the constant thermal cycling and moisture-heavy environments found in chilled water loops.

What is the resistance rating of the 025-40273-007 sensor?
This is an authentic 3000 Ohm leaving H2O sensor, calibrated specifically for the thermistor curves used in York industrial refrigeration and HVAC control systems.

Can I use this for entering water temperature (EWT) measurements?
While the resistance profile may be similar, the 025-40273-007 is technically designated as a leaving liquid sensor. Contractors should verify the specific probe length and lead requirements for EWT versus LWT locations.

How do I verify if this sensor is faulty?
Technicians should perform a resistance check using a high-quality multimeter and compare the Ohms to a standard temperature-resistance chart. If the York sensor shows an "open" circuit or a significant deviation from the 3k Ohm curve at ambient temperatures, replacement is necessary.
