含义
室外机冷凝器管温传感器开路或短路，影响系统压力控制和化霜判断。
常见原因
- 室外机管温传感器插头松动或脱落
- 传感器本身开路或短路损坏
- 传感器线束在室外长期老化断裂
- 探头与冷凝器铜管脱离导致检测偏差
- 强腐蚀性环境导致传感器引脚腐蚀
自助排查
- 断电后重新插拔室外机侧传感器连接器
- 用万用表测量传感器阻值是否符合当前温度对应值
- 检查传感器线束绝缘层是否龟裂破损
- 确保传感器探头紧贴冷凝器铜管并用卡簧固定
- 若阻值异常，更换同型号管温传感器
English
Meaning
Outdoor unit condenser coil temperature sensor open or short circuit. Affects system pressure control and defrost logic.
Common Causes
- Loose or disconnected outdoor unit coil sensor connector
- Open or short circuit failure of the sensor itself
- Aged wiring broken due to prolonged outdoor exposure
- Sensor probe detached from the condenser coil causing inaccurate readings
- Corroded sensor pins in harsh environments
Self-Check Steps
- Power off and reseat the outdoor unit sensor connector
- Measure sensor resistance with a multimeter and compare to the temperature-resistance chart
- Inspect sensor wiring insulation for cracking or damage
- Ensure the sensor probe is firmly attached to the condenser coil with its retaining clip
- Replace with a coil sensor of the same specification if resistance is abnormal
