含义
气体传感器异常。设备检测有害气体（VOC/甲醛/异味）的传感器读数异常或不可用。
常见原因
- 气体传感器敏感元件中毒——长期接触高浓度酒精或硅氧烷蒸气
- 传感器加热丝断裂导致无法达到工作温度
- 传感器老化——典型电化学传感器的使用寿命为2-3年
- 传感器周围残留高浓度异味物质导致读数持续偏高
- 传感器焊点松动或插座接触不良
自助排查
- 将净化器移至通风良好的新环境运行24小时，观察传感器读数是否下降
- 检查并清洁传感器外壳通风孔，确保气体可以自由扩散进入
- 避免在净化器附近使用高浓度酒精、消毒液或香薰产品
- 检查传感器模块在主板上的连接是否牢固
- 若上述方法均无效，传感器已到寿命需更换气体传感器模块
English
Meaning
Gas sensor anomaly. The sensor for detecting harmful gases (VOC/formaldehyde/odors) is reading abnormally or is unavailable.
Common Causes
- Gas sensor element poisoned by prolonged exposure to high concentrations of alcohol or siloxane vapors
- Broken heater wire inside the sensor preventing it from reaching operating temperature
- Sensor aging — typical electrochemical gas sensor lifespan is 2-3 years
- Residual high-concentration odorants near the sensor keeping readings artificially elevated
- Loose solder joints or socket connection on the sensor module
Self-Check Steps
- Move the purifier to a well-ventilated clean area and run for 24 hours to see if readings normalize
- Clean the ventilation holes on the gas sensor housing to ensure free gas diffusion
- Avoid using high-concentration alcohol, disinfectants, or scented products near the purifier
- Verify the sensor module is securely plugged into the main board connector
- If the above steps fail, the sensor has reached end-of-life and needs replacement
