含义
空调室外风机电机故障。E6 表示室外风机不转或转速异常,主板检测到风机反馈信号缺失或超出范围。室外风机不运转将导致冷凝器散热不良,系统高压升高并可能触发压缩机保护停机。
常见原因
- 室外风机电机烧毁,绕组开路或对地短路。
- 风机启动电容容量衰减或击穿,电机无法启动。
- 风机电机轴承卡滞或缺油,转子转动阻力过大。
- 风机扇叶被异物(树枝、塑料袋)卡住。
- 主板风机驱动电路(继电器或可控硅)损坏,无法输出电源给电机。
- 电机反馈信号线(霍尔信号或测速信号)断路。
自助排查
- 断电后用手拨动室外风机扇叶——应能灵活转动。若转动困难,检查是否有异物卡住或轴承卡死。
- 检查风机启动电容是否有鼓包、漏液或外壳变形——如有,更换同规格电容。
- 用万用表测量风机电机绕组阻值:主绕组和副绕组应有几欧姆到几十欧姆的阻值,对地绝缘应为无穷大。
- 检查电机接线端子是否松动、烧焦或有氧化——清洁并重新紧固。
- 室外风机维修涉及强电操作,建议联系 TCL 售后由专业技师更换风机电机或电容。
English
Meaning
The outdoor fan motor has a fault. E6 indicates the outdoor fan is not spinning or has abnormal speed, and the main board has detected missing or out-of-range fan feedback signals. An inoperative outdoor fan will cause poor condenser heat dissipation, elevated system high-side pressure, and may trigger compressor protection shutdown.
Common Causes
- The outdoor fan motor is burned out — open winding or short circuit to ground.
- The fan run capacitor has degraded in capacitance or is shorted; the motor cannot start.
- The fan motor bearings are seized or lack lubrication; the rotor has excessive rotational resistance.
- The fan blades are obstructed by foreign objects (branches, plastic bags).
- The fan drive circuit on the main board (relay or triac) is damaged and cannot output power to the motor.
- The motor feedback signal wire (Hall signal or tachometer signal) is broken.
Self-Check Steps
- After powering off, manually spin the outdoor fan blades — they should rotate freely. If rotation is difficult, check for foreign object obstruction or seized bearings.
- Check the fan run capacitor for bulging, leakage, or housing deformation — if found, replace with a capacitor of the same specification.
- Use a multimeter to measure the fan motor winding resistance: the main and auxiliary windings should each read a few ohms to tens of ohms; insulation resistance to ground should be infinite.
- Inspect the motor terminal connections for looseness, burning, or oxidation — clean and re-tighten.
- Outdoor fan repairs involve high-voltage electrical work. Contact TCL after-sales for a professional technician to replace the fan motor or capacitor.
