中文
含义
蒸发器风扇电机不转或转速异常，制冷效率下降。
常见原因
- 风扇电机绕组烧毁
- 风扇叶片被冰块卡住
- 风扇电机启动电容损坏
- 风扇供电线路断路
- 电机霍尔传感器故障
自助排查
- 断电后打开冷冻室检查风扇是否被冰卡住
- 手动拨动风扇叶片检查转动阻力
- 用万用表测量电机供电电压
- 测量电机绕组阻值判断是否烧毁
- 清理积冰后如仍不转需更换风扇电机
English
Meaning
Evaporator fan motor not running or running at abnormal speed, reducing cooling efficiency.
Common Causes
- Fan motor winding burnt
- Fan blade blocked by ice
- Fan start capacitor failed
- Fan power supply wiring open circuit
- Motor Hall sensor fault
Self-Check Steps
- Disconnect power, open freezer and check fan for ice blockage
- Manually rotate fan blade to feel resistance
- Measure fan motor supply voltage with multimeter
- Check motor winding resistance for burn-out
- Clear ice; if fan still does not spin, replace fan motor
