Ruud 47-102710-18 Discharge Line Thermistor RA20 RP17 RP20

Product Description

The RUUD 47-102710-18 is a discharge line thermistor sensor designed for use in residential air conditioner and heat pump systems. This sensor monitors refrigerant discharge line temperature, providing critical data to the system control board to protect the compressor and maintain efficient operation. Weighing just 0.07 pounds and measuring 3.1 inches in length, it is a compact, direct-replacement component. Installation is typically performed by a licensed HVAC technician as part of a diagnostic service call or scheduled maintenance procedure.

This discharge sensor is used on RUUD RA20, RP17, and RP20 series air conditioner and heat pump units. It is suited for residential split-system applications where accurate discharge temperature monitoring is required for system protection and performance. The sensor interfaces directly with the unit control board and is a common replacement item when fault codes indicate a discharge temperature sensor failure.
