Customer Questions and Answers for Temperature Sensor (Thermistor) by Samsung

This temperature sensor monitors refrigerator compartment temperature so the control board can regulate cooling. Replacing a failed sensor restores accurate temperature readings and helps the refrigerator maintain steady cooling performance. What it does:

• Detects internal air temperature and sends readings to the refrigerator control board
• Enables the control system to cycle the compressor and fans correctly
• Common symptoms of a bad sensor: inconsistent temperatures, refrigerator or freezer too warm or too cold
• Can cause frequent running, temperature-related error codes, or defrost/ice-making issues when faulty

• Disconnect power before servicing to avoid electrical shock
• Handle the sensor and wiring harness gently; connectors and sensing probes are fragile
• Route and secure wiring to match original routing to prevent pinching or false readings
