DA97-02019A - Samsung Refrigerator Temperature Sensor

This Refrigerator Temperature Sensor (DA97-02019A), manufactured by Samsung for Samsung refrigerators, is a vital component for maintaining the desired temperature within the refrigerator. It is often referred to as a thermostat or thermistor. This genuine part fits perfectly within your appliance's configuration, promising precise temperature regulation that ensures the perishables are stored safely, minimizing spoilage and extending their shelf life.

The sensor operates based on temperature-dependent resistance changes, strategically positioned to measure ambient temperatures accurately. Connected to a control circuit, it monitors these resistance changes and translates them to actionable temperature readings. Should deviations from the set target occur, the control circuit activates the refrigerator's cooling system to adjust the temperature, which includes components such as the compressor and fans. Keeping the sensor clean and functioning is crucial for your refrigerator's performance, with regular calibration and timely replacement when needed being essential.

Symptoms indicating a potential malfunction include inaccurate temperature readings within your appliance, leading to either overheated or overcooled compartments. If you notice your perishables spoiling faster or your refrigerator not maintaining its set temperature, it may be time to replace the sensor.

Before purchasing, be sure to verify your device's model number to ensure compatibility with the DA97-02019A part.
