含义
烤箱温度传感器（NTC）短路，温度检测值异常偏低。
常见原因
- NTC传感器内部短路
- 传感器受潮或进水导致短路
- 传感器线束绝缘破损短路
- 主控板NTC采样电路异常
自助排查
- 测量NTC传感器电阻值是否过低
- 检查传感器探头有无进水或受潮
- 烘干传感器后重新测量
- 检查线束绝缘层是否破损
- 参照阻值表判断是否正常
English
Meaning
The oven NTC temperature sensor is short-circuited; temperature reading abnormally low.
Common Causes
- NTC sensor internal short circuit
- Sensor damp or water ingress causing short
- Sensor wire insulation damaged shorting
- Main board NTC sampling circuit abnormal
Self-Check Steps
- Measure NTC sensor for abnormally low resistance
- Check sensor probe for moisture ingress
- Dry sensor and re-measure
- Check wire insulation for damage
- Compare against resistance chart
