1E - 三星 洗衣机

中文

含义

1E表示洗衣机主温度传感器——NTC热敏电阻出现故障。该传感器安装在洗衣机桶底部，直接测量洗涤水温，是主控板控制加热和温度保护的关键元件。

常见原因

1. NTC热敏电阻内部开路或短路（可用万用表测量确认）。
2. 传感器引脚与连接器之间的焊点开裂，信号时断时续。
3. 传感器表面覆盖大量水垢，影响热传导效率。
4. 传感器连接线束因振动摩擦导致绝缘层破损、短路。
5. 传感器老化，室温下阻值偏移超出规格（25℃时通常为5-10kΩ）。

自助排查

1. 拔掉电源插头，打开后盖或下方面板找到温度传感器。
2. 拔下连接器，用万用表测量传感器阻值（25℃：约5-10kΩ）。
3. 将传感器放入热水中（注意防水），观察阻值是否随温度升高而下降。
4. 检查连接器和线束是否完好。
5. 若传感器损坏，需更换同规格NTC热敏电阻，建议联系售后。

English

Meaning

1E indicates a fault with the washer main temperature sensor (NTC thermistor). This sensor is mounted at the bottom of the washer tub and directly measures the wash water temperature. It is a critical component for heater control and temperature protection.

Common Causes

1. Internal open or short circuit of the NTC thermistor.
2. Cracked solder joint at the sensor pin-to-connector junction causing intermittent connection.
3. Heavy limescale covering the sensor surface, reducing thermal conduction efficiency.
4. Sensor wiring insulation worn by vibration, causing intermittent shorts.
5. Aged thermistor with room-temperature resistance significantly outside specification.

Self-Check Steps

1. Unplug the washer; open the rear panel or lower panel to access the temperature sensor.
2. Disconnect the connector and measure sensor resistance with a multimeter (25°C: about 5-10kΩ).
3. Immerse the sensor in hot water (keep the connector dry) and confirm resistance decreases with rising temperature.
4. Inspect the connector and wiring for damage.
5. Replace the NTC thermistor if it tests faulty — contact Samsung for the correct part.
