含义
冷冻室温度传感器故障。检测冷冻室温度的NTC热敏电阻异常，导致冷冻室温度失控——可能过度制冷冻坏食物，或制冷不足导致解冻。
常见原因
- 冷冻室温度传感器开路/短路
- 传感器探头被厚冰包裹导致响应迟缓
- 冷冻室传感器线束在门铰链处反复弯折断裂
- 传感器密封套进水导致阻值异常
- 传感器与主板连接器端子锈蚀
自助排查
- 断电后取出冷冻室抽屉，找到传感器并测量阻值（-18℃约15-30kΩ）
- 清除传感器周围冰层，确保探头与空气接触
- 检查门铰链处线束有无折断痕迹
- 如损坏，需更换冷冻室温度传感器组件
English
Meaning
Freezer compartment temperature sensor failure. The NTC thermistor for the freezer is abnormal, causing temperature失控 — either excessive freezing that damages food, or insufficient cooling leading to thawing.
Common Causes
- Open or shorted freezer temperature sensor
- Sensor probe encased in thick ice causing slow thermal response
- Sensor wiring broken at the hinge pivot point from repeated door flexing
- Water ingress into the sensor sealing sleeve causing abnormal resistance
- Corroded sensor pins at the main board connector
Self-Check Steps
- Power off, remove freezer drawers, locate the sensor and measure resistance (typically 15-30kΩ at -18°C)
- Clear ice buildup around the sensor to restore air contact
- Check the wiring at the door hinge for signs of breakage
- If damaged, replace the freezer temperature sensor assembly
