中文
含义
冷柜NTC温度传感器信号异常，系统自动停机保护。
常见原因
- 冷柜传感器开路或短路
- 传感器受潮导致阻值漂移
- 传感器线束插头腐蚀
- 控制板温度检测通道故障
自助排查
- 断开电源找到冷柜传感器位置
- 检查插头是否受潮氧化
- 用万用表测量传感器阻值
- 阻值异常需更换同型号传感器
- 如传感器正常则检修控制板
English
Meaning
Freezer NTC temperature sensor signal abnormal, system auto-stops for protection.
Common Causes
- Freezer sensor open or short circuit
- Sensor damp causing resistance drift
- Sensor connector corroded
- Control board temperature detection channel fault
Self-Check Steps
- Disconnect power and locate the freezer sensor
- Check connector for moisture and oxidation
- Measure sensor resistance with multimeter
- Replace sensor if resistance is abnormal
- If sensor is normal, service the control board
