中文
含义
冷藏室NTC温度传感器信号异常或开路/短路。
常见原因
- NTC传感器内部故障或老化
- 传感器线束插头接触不良或氧化
- 传感器安装位置偏移导致检测偏差
- 主控板温度采样电路损坏
自助排查
- 断开电源，找到冷藏室NTC传感器位置
- 拔下传感器插头，检查触点是否氧化或松动
- 用万用表测量传感器阻值（常温约2-10kΩ）
- 阻值异常则更换同型号NTC传感器
- 如传感器正常则需检修主控板
English
Meaning
Refrigerator compartment NTC temperature sensor signal abnormal (open or short circuit).
Common Causes
- Internal NTC sensor fault or aging
- Sensor connector loose or oxidized
- Sensor shifted from correct mounting position
- Main board temperature sampling circuit failure
Self-Check Steps
- Disconnect power and locate the fridge NTC sensor
- Unplug the sensor and check connector for oxidation
- Measure sensor resistance with multimeter (2-10kΩ at room temp)
- Replace with same type NTC if resistance is out of range
- If sensor is normal, main board requires service
