电动卷帘门用久了，难免出现各种小毛病。遥控器按了没反应、门升到一半卡住了、关门关不严——这些问题大部分自己就能解决。以下是常见的5类故障及排除方法。

Electric rolling shutter doors are prone to various minor issues after prolonged use. The remote control doesn't respond when pressed, the door gets stuck halfway up, and the door doesn't close tightly - most of these problems can be solved by oneself. The following are 5 common types of faults and their troubleshooting methods.

故障一：遥控器失灵。 这是常见的故障。第一步检查电池——遥控器电池可能耗尽或电量不足。更换同型号新电池，确保正负出色方向正确。第二步观察指示灯——遥控器前端中间的遥控亮点在使用时是否会亮，如果不亮说明遥控器坏了。也可能是亮点处被弄脏，用湿布擦拭即可。第三步检查信号干扰——遥控距离太远或周围有无线干扰源（如Wi-Fi路由器、手机信号等），也会导致遥控器失效。将遥控器靠近门再操作试试。第四步重新对码——遥控器可能没有对码，按说明书指导完成对码操作即可。

Fault 1: Remote control malfunction. This is a common malfunction. The first step is to check the battery - the remote control battery may be depleted or low. Replace the battery with a new one of the same model, ensuring that the positive and negative directions are correct. Step 2: Observe the indicator light - whether the remote control bright spot in the middle of the front end of the remote control will light up during use. If it does not light up, it indicates that the remote control is broken. It may also be that the bright spot is dirty, just wipe it with a damp cloth. The third step is to check for signal interference - if the remote control is too far away or there are wireless interference sources around (such as Wi Fi routers, mobile phone signals, etc.), it can also cause the remote control to malfunction. Try operating the remote control close to the door. Step 4: Re code - The remote control may not be properly coded. Follow the instructions in the manual to complete the coding operation.

故障二：门体运行卡顿或噪音大。 导轨内积累灰尘杂物会导致卡顿。用软毛刷或吸尘器清理导轨内部及门板表面的灰尘杂物。导轨缺乏润滑也会导致运行不畅、噪音大。使用专用润滑油或润滑脂涂抹导轨。检查机械部分有无卡阻，若有则消除卡阻、清理障碍物。

Fault 2: The door body is stuck or making loud noise during operation. Accumulation of dust and debris inside the guide rail can cause jamming. Use a soft bristled brush or vacuum cleaner to clean the dust and debris inside the guide rail and on the surface of the door panel. Lack of lubrication on the guide rail can also lead to poor operation and loud noise. Apply specialized lubricating oil or grease to the guide rail. Check if there is any blockage in the mechanical part, and if so, eliminate the blockage and clean up the obstacles.

故障三：电机不转或转速慢。 检查线路是否断路。检查停止按钮是否复位。检查限位开关是否动作。检查负载是否过大。如电机烧损，需更换电机。如仅是转速慢，说明电机还能运作，检查线路是否接触不良。

Fault 3: The motor does not rotate or has a slow speed. Check if the circuit is broken. Check if the stop button has been reset. Check if the limit switch is activated. Check if the load is too heavy. If the motor is burned, it needs to be replaced. If the speed is only slow, it indicates that the motor can still operate. Check whether the circuit has poor contact.

故障四：限位跑偏。 门体升不到顶或降不到底。松开限位器上的螺钉。将门帘升降到确定位置。旋转限位螺套，听到“嘀嗒”一声后停止旋转，将螺钉拧紧。限位不准会导致门体过卷或撞击地面，损伤门体或电机。

Fault 4: Limit deviation. The door cannot be raised to the top or lowered to the bottom. Loosen the screw on the limiter. Raise and lower the door curtain to the designated position. Rotate the limit screw sleeve, stop rotating after hearing a "beep" sound, and tighten the screw. Inaccurate positioning can cause the door to roll over or hit the ground, damaging the door or motor.

故障五：断电后无法手动操作。 电动卷帘门一般配有断电手动释放系统。断电情况下可通过手动装置操作门体。如手动拉链拉不动，检查拉链是否断裂或卡顿。每月检查一次手动拉链和手动速放装置，确保其操作灵活。

Fault 5: Unable to manually operate after power failure. Electric rolling shutter doors are generally equipped with a power-off manual release system. In the event of a power outage, the door can be operated manually through a device. If the manual zipper cannot be pulled, check if the zipper is broken or stuck. Check the manual zipper and manual quick release device once a month to ensure their flexible operation.

预防性维护建议：每3个月对导轨进行润滑。每月检查电机运行状态。定期清理导轨灰尘。发现问题及时处理，避免小问题拖成大故障。

Preventive maintenance recommendation: lubricate the guide rail every 3 months. Check the operation status of the motor every month. Regularly clean the dust on the guide rail. Identify and address issues promptly to prevent minor problems from escalating into major malfunctions.
