中文
含义
化霜NTC温度传感器信号异常，化霜循环可能无法正常结束。
常见原因
- 化霜传感器损坏或失效
- 传感器插头进水腐蚀
- 化霜加热器附近的传感器受热过度
- 连接线路断裂
自助排查
- 检查化霜传感器是否被冰层覆盖
- 拔下传感器检查插头有无腐蚀
- 测量阻值是否在正常范围（0℃约33kΩ）
- 阻值异常则更换化霜传感器
- 检查化霜加热器是否持续加热导致传感器过载
English
Meaning
Defrost NTC temperature sensor signal abnormal, defrost cycle may not end properly.
Common Causes
- Defrost sensor damaged or failed
- Sensor connector corroded by moisture
- Sensor near heater overheated
- Wiring harness broken
Self-Check Steps
- Check if defrost sensor is covered by ice
- Unplug sensor and inspect connector for corrosion
- Measure resistance (approx 33kΩ at 0°C)
- Replace defrost sensor if resistance is abnormal
- Check if defrost heater runs continuously overheating the sensor
