Ruud PD476610 Thermistor Kit

Product Description

The RUUD PD476610 is a thermistor kit designed for use in RUUD heating and cooling systems. A thermistor is a temperature-sensing resistor that feeds real-time temperature data to the system control board, enabling accurate staging, defrost cycling, and safety shutoffs. This kit provides the components needed to restore proper temperature sensing after sensor failure or as part of a scheduled maintenance repair. Licensed HVAC technicians are the primary installers of this part.

This thermistor kit is suited for residential HVAC applications where the original temperature sensor has failed or drifted out of calibration. It is used in systems that rely on thermistor-based feedback to manage refrigerant circuit monitoring, air temperature sensing, or heat exchanger protection. When a thermistor fails, it can trigger fault codes, cause erratic operation, or prevent the system from running altogether.

Key Features

• OEM-style thermistor kit for RUUD heating and cooling equipment
• Restores accurate temperature sensing to the system control circuit
• Addresses thermistor failure-related fault codes and erratic operation
• Kit format includes the components needed for a complete sensor replacement

Compatibility

Designed as an OEM-style replacement thermistor kit for RUUD residential heating and cooling systems.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect power to the unit at the disconnect switch or breaker before accessing internal components. Thermistor connections are low-voltage signal wiring and should be handled carefully to avoid damage to the control board. Follow the equipment manufacturer service manual for sensor location and mounting procedure.
