含义
7E表示洗衣机冷凝器温度传感器（NTC热敏电阻）出现故障。该传感器用于带烘干功能的洗衣机，安装在冷凝器（热交换器）上，监测烘干过程中的温度。
常见原因
- 冷凝器NTC热敏电阻开路或短路。
- 传感器连接器在高温环境下氧化，接触不良。
- 传感器安装位置松动，未与冷凝器翅片紧密接触。
- 传感器线束在长期高温下绝缘老化龟裂。
- 冷凝器风道堵塞导致温度异常，间接触发传感器报警。
自助排查
- 拔掉电源插头，找到冷凝器上的温度传感器（位于烘干风道内）。
- 拔下连接器，用万用表测量传感器阻值并与标准值对照。
- 检查传感器是否牢固安装在冷凝器上。
- 检查冷凝器风道是否有绒毛积聚堵塞，清理风道。
- 如果传感器损坏，需更换同规格NTC传感器，联系售后。
English
Meaning
7E indicates a fault with the condenser temperature sensor (NTC thermistor) on washers with drying functionality. This sensor is mounted on the condenser (heat exchanger) to monitor drying cycle temperature.
Common Causes
- Open or short circuit of the condenser NTC thermistor.
- Oxidized connector contacts due to high-temperature environment.
- Loose sensor mounting — not making firm contact with the condenser fins.
- Aged and cracked sensor wiring insulation from prolonged heat exposure.
- Blocked condenser air duct causing abnormal temperatures that trigger a sensor alarm.
Self-Check Steps
- Unplug the washer. Locate the temperature sensor on the condenser (inside the drying air duct).
- Disconnect and measure sensor resistance with a multimeter — compare to the standard value chart.
- Check that the sensor is firmly attached to the condenser.
- Inspect the condenser air duct for lint buildup and clean if necessary.
- Replace the sensor if readings are out of spec — contact Samsung.
