York Thermistor Set MHW551A026

This is a thermistor sensor assembly used in compatible York air conditioning systems. Thermistors measure temperature through changes in electrical resistance, allowing the unit’s controller to monitor operating conditions at designated points in the system. These readings are important for refrigerant circuit monitoring, temperature regulation and equipment protection. The MHW551A026 assembly is intended for replacing the corresponding temperature sensor set during servicing or repair of compatible York units.
