中文
含义
烤箱温度传感器（NTC）开路，控制器检测不到温度信号。
常见原因
- 烤箱NTC传感器内部断路
- 传感器连接端子松动
- 传感器线束断裂
- 主控板NTC接口电路故障
- 传感器插头氧化接触不良
自助排查
- 检查NTC传感器插头是否插紧
- 测量传感器两端电阻是否无穷大
- 检查探头和线束有无断裂
- 短接NTC接口判断主控板是否正常
- 检查插头有无氧化
English
Meaning
The oven NTC temperature sensor is open-circuited; no temperature signal detected.
Common Causes
- Oven NTC sensor open circuit
- Sensor connector terminal loose
- Sensor wire broken
- Main board NTC interface circuit faulty
- Sensor plug oxidized poor contact
Self-Check Steps
- Check NTC sensor connector is fully seated
- Measure sensor resistance expecting open circuit
- Check probe and wire for breakage
- Short NTC connector to test main board
- Check plug pins for oxidation
