Description
The York S1-025-52097-000 Defrost Thermistor Temperature Sensor is a temperature-sensing component used in heat pump and HVAC systems to monitor coil conditions during defrost operation. Installed near the outdoor coil assembly, it measures thermal changes and communicates temperature data to the control circuitry responsible for managing defrost cycles. it is commonly applied in residential and commercial heating equipment where frost accumulation can affect normal operation. As part of the control arrangement, it provides temperature response used for cycle initiation and termination, supporting coordinated operation.
