lime-colored housing and precision calibration make it a cornerstone for maintaining HVAC system efficiency and preventing safety hazards such as carbon monoxide buildup

The spring-loaded Teflon construction is resistant to chemicals

This 60 Hz synchronous motor is an essential component for maintaining reliable hydronic heating system control

York S1-025-47281-000 Sensor 321894-708 With two sensor inputs andEnsuring reliable defrost cycles in heat pump applications requires high precision feedback from the evaporator coil. The York S1 025 47281 000 Temp Defrost Thermistor Sensor is a critical OEM replacement part designed for York, Coleman, and Luxaire systems. This 10k ohm thermistor provides real time resistance input to the control board, allowing the system to initiate and terminate defrost modes based on actual coil temperatures rather than fixed
