中文
含义
冷藏室温度传感器（NTC）开路或短路，无法准确检测冷藏室温度。
常见原因
冷藏室NTC传感器故障、传感器线束连接松动或断裂、控制板传感器接口电路异常。
自助排查
- 断电重启看代码是否消失。2. 检查传感器线束连接器是否牢固。3. 测量传感器电阻（-18°C约16kΩ，25°C约10kΩ）。4. 阻值异常则更换冷藏室传感器。
English
Meaning
Fresh food compartment temperature sensor (NTC) open or short — cannot accurately sense refrigerator temperature.
Common Causes
Faulty refrigerator NTC sensor, loose or broken sensor harness connection, or control board sensing circuit issue.
Self-Check Steps
- Power cycle and check if code clears. 2. Verify sensor harness connector is secure. 3. Measure sensor resistance (approx 16kΩ at -18°C, 10kΩ at 25°C). 4. Replace fresh food sensor if resistance is abnormal.
