E6 - 三星 空调

中文

含义

E6表示空调室外机风机电机或其驱动电路出现故障。室外风机负责为室外换热器散热，风机不转会导致制冷/制热效率急剧下降，系统压力异常。

常见原因

1. 室外风机电机烧毁或线圈断路。
2. 风机启动电容失效（定频机型）。
3. 风机叶轮被异物卡住或断裂。
4. 风机电机连接器松动或线束断裂。
5. 主控板风机驱动电路损坏。

自助排查

1. 关闭空调电源并断开室外机电源。
2. 打开室外机侧板，手动拨动风机叶轮检查是否卡滞。
3. 检查风机电机线束和连接器是否完好。
4. 用万用表测量电机绕组电阻判断是否烧毁。
5. 若风机损坏需更换，联系售后处理。

English

Meaning

E6 indicates an outdoor unit fan motor or its drive circuit fault. The outdoor fan dissipates heat from the outdoor heat exchanger. A non-functioning fan causes a sharp drop in cooling/heating efficiency and abnormal system pressure.

Common Causes

1. The outdoor fan motor is burned out or the coil is open-circuit.
2. The fan start capacitor has failed (fixed-speed models).
3. The fan impeller is jammed by foreign objects or broken.
4. The fan motor connector is loose or the wiring harness is broken.
5. The fan drive circuit on the main control board is damaged.

Self-Check Steps

1. Turn off the A/C power and disconnect outdoor unit power.
2. Open the outdoor unit side panel and manually turn the fan impeller to check for binding.
3. Check the fan motor wiring harness and connector for integrity.
4. Use a multimeter to measure the motor winding resistance — check if burned.
5. If the fan is damaged, replace it — contact service.
