23E - 三星 冰箱

中文

含义

23E表示冰箱化霜传感器（除霜热敏电阻）出现异常。该传感器安装在蒸发器上监测化霜温度，控制系统根据其读数决定化霜加热器的工作周期。

常见原因

1. 传感器NTC热敏电阻开路或短路。
2. 传感器插头松动或线束断裂。
3. 传感器安装位置偏移，未与蒸发器紧密接触。
4. 传感器长期处于高湿环境，引脚腐蚀或内部元件老化。
5. 主控板检测电路异常导致误报。

自助排查

1. 拔掉冰箱电源，等待5分钟后重新上电。
2. 打开冷冻室蒸发器盖板，找到安装在蒸发器翅片上的化霜传感器。
3. 检查传感器插头是否插紧，线束是否完好。
4. 用万用表测量传感器阻值（在冷冻温度下阻值较高，常温下约5-15kΩ）。
5. 若传感器损坏需更换，联系售后。

English

Meaning

23E indicates an abnormality with the refrigerator defrost sensor (defrost thermistor). This sensor is mounted on the evaporator to monitor defrost temperature. The control system uses its readings to determine the defrost heater operating cycle.

Common Causes

1. The sensor NTC thermistor is open or short circuit.
2. The sensor connector is loose or the wiring harness is broken.
3. The sensor is displaced from its mounting and not making firm contact with the evaporator.
4. The sensor has been in a high-humidity environment for long — pin corrosion or internal element aging.
5. The main board detection circuit is abnormal, causing a false alarm.

Self-Check Steps

1. Unplug the refrigerator, wait 5 minutes, then restore power.
2. Open the freezer evaporator cover and locate the defrost sensor on the evaporator fins.
3. Check that the sensor connector is firmly seated and the wiring is intact.
4. Use a multimeter to measure the sensor resistance (higher at freezer temperatures, about 5-15kΩ at room temperature).
5. If the sensor is damaged, replace it — contact service.
