含义
蒸发器风机故障——冷冻室蒸发器风扇不转或转速异常,冷量无法循环。
常见原因
- 蒸发器风机电机绕组烧毁或轴承卡死
- 风叶被冰霜卡住或异物缠绕
- 风机连接器松动或线束断裂
- 风机驱动电压异常(主板供电故障)
- 风机霍尔传感器损坏导致反馈丢失
- 长期使用后电机磨损老化
自助排查
- 断电后手动转动风扇叶片,检查是否卡滞
- 清除风机周围的冰霜和异物
- 检查风机连接器是否插接到位
- 上电后听是否有风机运转声,若无则测量供电电压
- 若风机电机损坏,需更换同型号蒸发器风机

Meaning
Evaporator fan motor fault — freezer evaporator fan not spinning or abnormal speed. Cold air cannot circulate.
Common Causes
- Burned-out fan motor winding or seized bearing
- Fan blade blocked by frost or debris
- Loose fan connector or broken wiring
- Abnormal fan drive voltage (mainboard power supply fault)
- Failed Hall-effect sensor causing RPM feedback loss
- Normal motor wear after prolonged use
Self-Check Steps
- Power off and manually rotate the fan blade to check for binding
- Remove any frost or debris around the fan
- Verify the fan connector is fully seated
- Power on and listen for fan operation; if silent, measure the supply voltage
- Replace the evaporator fan motor with the same specification if damaged
