含义
烤箱温度传感器（RTD）开路——无电阻读数
常见原因
- RTD 探头元件断裂
- 传感器连接器断开
- 传感器线束断线
自助排查
- 检查控制板上的 RTD 线束连接
- 测量传感器是否开路（电阻无穷大）
- 检查传感器线束路径是否有切断或断裂
- 如传感器开路，更换 RTD 传感器
English
Meaning
Oven temperature sensor (RTD) open circuit — no resistance reading
Common Causes
- RTD probe element broken
- Sensor connector disconnected
- Wire break in sensor harness
Self-Check Steps
- Check RTD harness connection at control board
- Measure sensor for open circuit (infinite resistance)
- Inspect sensor wire path for cuts or breaks
- Replace RTD sensor if open
