Rheem rtg20006ar Inlet Thermistor White

Product Description

The RHEEM rtg20006ar is an inlet thermistor used in tankless water heater systems to monitor incoming cold-water temperature. The thermistor feeds a real-time temperature signal to the unit's control board, allowing the system to calculate and maintain the correct temperature rise across the heat exchanger. Accurate inlet sensing is essential for stable outlet temperature and efficient operation. This replacement component is installed by licensed plumbers or HVAC technicians servicing Rheem tankless water heating equipment.

The rtg20006ar is designed for use in Rheem tankless water heater applications where the inlet thermistor has failed or is reading out of specification. A faulty inlet thermistor can cause erratic temperature output, error codes, or system shutdown. Replacing the thermistor with the correct OEM-style part restores accurate sensing and normal operation. This part is identified by its white color, which may aid in identification during service.

Key Features
