S1‑025‑47281‑000 York / Coleman Temp Defrost Thermistor Sensor

The S1‑025‑47281‑000 York / Coleman Temperature Defrost Thermistor Sensor is an OEM replacement sensor used in heat pump systems to monitor coil temperature during the defrost cycle. This thermistor provides accurate temperature feedback to the defrost control board, ensuring proper system operation, efficient frost removal, and reliable heating performance in cold‑weather conditions.

Designed to meet original factory specifications, this sensor restores correct system behavior when the existing thermistor becomes damaged, out of range, or fails intermittently. Ideal for service technicians performing heat pump diagnostics, seasonal maintenance, or full defrost‑system repairs.

Compatible with select York, Coleman, and Luxaire heat pump models using this style of temperature sensor.
