含义
蒸发器风扇故障。冷冻室内的蒸发器散热风扇不转或转速异常，导致冷量无法循环送入冷藏室和冷冻室，制冷效果明显下降。
常见原因
- 蒸发器风扇电机绕组烧毁或开路
- 风扇扇叶被冰层卡住无法旋转
- 风扇轴承磨损导致噪音或停转
- 风扇供电插头松动或线路断路
- 风扇驱动MOS管或霍尔传感器损坏
自助排查
- 打开冷冻室门听是否有风扇运转声
- 断电后手动拨动扇叶检查是否被厚冰卡住
- 如手动除冰后风扇恢复，说明化霜系统也需检修
- 若扇叶转动灵活但不转，测量风扇供电电压（通常12V DC）
English
Meaning
Evaporator fan failure. The fan that circulates cold air from the evaporator throughout the fridge and freezer compartments has stopped or runs abnormally, significantly reducing cooling performance.
Common Causes
- Burned-out or open evaporator fan motor winding
- Fan blade blocked by ice buildup
- Worn fan bearings causing noise or stall
- Loose fan power connector or broken supply wire
- Failed fan drive MOSFET or Hall sensor in DC fan motors
Self-Check Steps
- Open the freezer door and listen for the fan running
- Power off and manually rotate the fan blade to check for ice blockage
- If defrosting restores fan operation, the defrost system also needs attention
- If the blade spins freely but the fan does not run, measure the fan supply voltage (typically 12V DC)
