York Sensors

York sensors are official OEM replacement sensing components for York HVAC equipment, including residential and commercial air conditioners, heat pumps, and Applied commercial systems such as chillers and rooftop units manufactured under the York brand by Johnson Controls. Sensors in York HVAC systems measure temperature, pressure, and flow at critical points in the refrigeration circuit and air distribution system, feeding real-time data to the unit's control board or chiller control panel to maintain precise operation, protect the equipment from out-of-range conditions, and trigger safety responses when needed. The York sensors category at SupplyHouse spans temperature sensors covering leaving water, entering water, suction line, liquid line, outdoor ambient, duct, and water applications, pressure sensors for residential condensing units, flow sensors for Applied chiller systems, and temperature sensors covering the negative 40 degrees C to 110 degrees C range in male and female connector configurations. All York sensors at SupplyHouse are official OEM replacement parts. Identifying the correct sensor by York unit model number before ordering is required, as sensor part numbers are application-specific across the York equipment lineup.

KEY SUBCATEGORIES / PRODUCT TYPES

York Leaving and Entering Water Temperature Sensors for Applied Equipment

York leaving water and entering water temperature sensors are Applied OEM sensors for York commercial chiller systems that measure chilled water or condenser water temperature as it enters and leaves the heat exchanger. The chiller's control panel uses those readings to maintain leaving water temperature setpoint, modulate capacity, and protect the heat exchanger from operating outside its safe range. When a sensor drifts or fails, the chiller faults. Getting the right OEM part back in fast matters. The current active leaving/entering temperature sensor is the 025-53146-000 (SKU 025-53146-000). It is a genuine OEM York replacement and carries the yellow label that identifies current-generation sensors in this series. Confirming the specific York chiller model number before ordering is required, as sensor configurations vary across the Applied equipment lineup.

BUYING GUIDE / HOW TO CHOOSE

Selecting the right York sensor starts with the York unit's model number and the specific sensor's part number from the unit's wiring diagram or the failed sensor itself. York sensor part numbers are application-specific and equipment-specific. A temperature sensor for a York chiller's leaving water circuit and a temperature sensor for a York residential condensing unit's suction line serve entirely different control functions and are not interchangeable.

The first split in the York sensor category is between Applied commercial equipment sensors and residential equipment sensors. Applied sensors, identified by part number prefixes in the 025 and 325 series, serve York commercial chillers, rooftop units, and applied HVAC systems. Residential sensors, identified by S1 prefixes, serve York residential air conditioners and heat pumps. Using an Applied sensor in a residential unit or vice versa will not function correctly and may cause control board faults or sensor faults.

For Applied chiller sensors, the York unit model number is the critical starting point because different York chiller families use different sensor generations. The current leaving/entering temperature sensor 025-53146-000 carries the yellow label that identifies genuine current-generation OEM parts in this series. Order by current active part number rather than discontinued predecessors to ensure the currently produced sensor is received.

For the negative 40 degrees C to 110 degrees C residential sensor series, the connector gender matters. The male (S1-6043485) and female (S1-02550564000) variants serve different wiring harness configurations. Getting the connector type confirmed before ordering avoids a return.

York's commercial HVAC parts ecosystem, including HVAC Navigator from Johnson Controls and the York Chiller Parts app, provides additional compatibility lookup tools for Applied chiller sensors when the unit model number is known. SupplyHouse's own compatibility lookup tool on each York sensor product page allows model number verification before ordering.

FAQs

What is a York sensor and what does it do in a York HVAC system?

A York sensor is an official OEM electronic sensing component that measures temperature, pressure, or flow at a specific point in a York HVAC system and transmits that measurement to the unit's control board or chiller control panel. The control uses the sensor's input to maintain precise setpoints, protect the equipment from out-of-range conditions, and trigger safety responses when needed. York sensors serve both residential air conditioners and heat pumps, where sensors monitor refrigerant pressure, ambient temperature, and suction or liquid line temperature, and Applied commercial chillers, where sensors monitor leaving and entering water temperature, refrigerant line temperatures, and water flow.
