含义
冷藏室温度传感器故障。检测冷藏室温度的NTC热敏电阻异常，可能导致冷藏室温度显示错误、制冷不停机或冷藏室温度过高。
常见原因
- 冷藏室传感器开路或短路
- 传感器线束在箱体穿线处断裂
- 传感器插头腐蚀或接触不良
- 传感器阻值漂移导致温度检测偏差超过5℃
- 主控板上传感器分压电阻变值
自助排查
- 断电后找到冷藏室传感器（通常在蒸发器附近），测量阻值
- 检查传感器线束和插头有无破损或氧化
- 清洁传感器探头表面结霜或冰垢
- 更换同型号冷藏室温度传感器
English
Meaning
Refrigerator compartment temperature sensor failure. The NTC thermistor that monitors fridge temperature is abnormal, causing incorrect temperature display, continuous compressor operation without stopping, or excessively high fridge temperature.
Common Causes
- Open or short-circuited fridge compartment thermistor
- Sensor wiring broken at the cabinet feed-through point
- Corroded or loose sensor connector
- Sensor resistance drifted, causing temperature reading error exceeding 5°C
- Changed divider resistor value on the main control board
Self-Check Steps
- Power off, locate the fridge sensor (near the evaporator), and measure its resistance
- Inspect the wiring and connector for damage or corrosion
- Clean the sensor probe surface of frost or ice buildup
- Replace with a matching fridge compartment temperature sensor
