1. 风扇叶片被冰霜卡住
2. 风扇电机损坏
3. 风扇连接线束断裂
4. 控制板风扇驱动电路异常

自助排查

1. 倾听冷冻室是否有正常的风扇运转声音，如无声音可能风扇不转。
2. 将冷冻室食物取出，断电彻底化霜（6-8 小时），排除冰堵造成的机械卡滞。
3. 化霜后重新上电，观察风扇是否恢复运转。
4. 如风扇仍不转，需检测风扇供电及电机状态。

English

Meaning

Freezer compartment evaporator fan motor fault. The freezer fan circulates cold air throughout the freezer compartment.

Common Causes

1. Fan blade jammed by frost or ice
2. Fan motor damaged
3. Fan wiring harness broken
4. Control board fan drive circuit abnormal

Self-Check Steps

1. Listen for normal fan operation sounds in the freezer; silence suggests the fan is not running.
2. Remove food from the freezer, power off and fully defrost (6-8 hours) to eliminate ice-induced mechanical jamming.
3. After defrosting, power on and observe whether the fan resumes operation.
4. If the fan still does not run, check the fan power supply and motor condition.
5. Fan replacement involves freezer air duct disassembly; contact Hisense service for assistance.
