含义
21E表示冰箱冷藏室风扇电机不运转。部分三星冰箱在冷藏室也配备独立风扇以改善空气循环和温度均匀性，风扇故障会导致冷藏室局部温度偏高。
常见原因
- 风扇电机线圈断路或烧毁。
- 风扇电机轴承卡死或润滑不良。
- 电机连接器松动或线束破损。
- 风道被食物包装堵塞，风扇转动风量不足或完全受阻。
- 主控板风扇输出电路故障。
自助排查
- 拔掉冰箱电源，打开冷藏室门，找到风扇位置（通常在冷藏室后壁风道内）。
- 检查风道出风口是否被食物或包装遮挡，清理后重新上电测试。
- 手动拨动风扇叶轮感受转动阻力，必要时拆下风扇清洁。
- 用万用表测量电机绕组电阻判断是否开路。
- 若风扇损坏需更换，请联系售后。
English
Meaning
21E indicates the refrigerator compartment fan motor is not running. Some Samsung refrigerators have a dedicated fan in the fresh food compartment to improve air circulation and temperature uniformity. Fan failure causes localized warm spots.
Common Causes
- The fan motor coil is open-circuit or burned out.
- The fan motor bearing is seized or poorly lubricated.
- The motor connector is loose or the wiring is damaged.
- The air duct is blocked by food packaging, restricting airflow or stopping the fan entirely.
- The fan drive circuit on the main control board is faulty.
Self-Check Steps
- Unplug the refrigerator, open the refrigerator door, and locate the fan (usually inside the rear wall air duct).
- Check if the air vent is blocked by food or packaging — clear it and retest.
- Manually turn the fan impeller to feel for resistance — remove and clean the fan if needed.
- Use a multimeter to measure the motor winding resistance — check for open circuit.
- If the fan is damaged, replace it — contact service.
