含义
41E表示冰箱蒸发器温度传感器（NTC热敏电阻）出现故障。该传感器安装在冷藏室蒸发器上，用于监测蒸发器的制冷温度，帮助控制化霜循环和制冷效率。
常见原因
- 传感器NTC热敏电阻开路或短路。
- 传感器插头松动或线束断裂。
- 传感器探头从蒸发器安装位置脱落。
- 传感器长期受潮氧化导致阻值漂移。
- 主控板上对应检测电路故障。
自助排查
- 拔掉冰箱电源，等待5分钟重新上电。
- 打开冷藏室后壁盖板，找到蒸发器上的传感器。
- 检查传感器插头和线束是否完好插紧。
- 用万用表测量传感器阻值是否在正常范围（冷藏温度下阻值较高）。
- 若传感器损坏需更换，联系售后。
English
Meaning
41E indicates a fault with the refrigerator evaporator temperature sensor (NTC thermistor). This sensor is mounted on the refrigerator compartment evaporator to monitor the evaporator cooling temperature, helping control the defrost cycle and cooling efficiency.
Common Causes
- The sensor NTC thermistor is open or short circuit.
- The sensor connector is loose or the wiring harness is broken.
- The sensor probe has fallen out of its mounting position on the evaporator.
- The sensor has been moisture-damaged over time, causing resistance drift.
- The corresponding detection circuit on the main board is faulty.
Self-Check Steps
- Unplug the refrigerator, wait 5 minutes, then restore power.
- Open the refrigerator rear wall cover and locate the sensor on the evaporator.
- Check that the sensor connector and wiring are intact and firmly seated.
- Use a multimeter to measure sensor resistance — verify it is within the normal range (higher at refrigerator temperatures).
- If the sensor is damaged, replace it — contact service.
