1. 檢查電源和電路：檢查電卷簾門的電源是否正常，并檢查電路連接是否松動或短路。使用萬用表或電壓表測量電源電壓是否穩定。

1. Check the power supply and circuit: First, check if the power supply of the electric roller shutter door is normal, and check if the circuit connection is loose or short circuited. Use a multimeter or voltmeter to measure whether the power supply voltage is stable.

2. 檢查電機本身：如果電源和電路正常，可能是電機本身出現故障。可以通過以下步驟進行檢查：

2. Check the motor itself: If the power supply and circuit are normal, it may be a malfunction of the motor itself. The following steps can be used for inspection:

a. 檢查電機是否正常運轉：將電機直接連接到電源上，觀察電機是否能夠正常轉動。如果不能轉動，可能是電機內部損壞，需要更換電機。

a. Check if the motor is running properly: Connect the motor directly to the power supply and observe if the motor can rotate normally. If it cannot rotate, it may be due to internal damage to the motor, which needs to be replaced.

b. 檢查電機繞組和碳刷：拆開電機外殼，檢查電機繞組是否有斷裂或燒壞的情況。同時檢查電機的碳刷是否磨損嚴重，需要更換。

b. Check the motor winding and carbon brush: Remove the motor casing and check if the motor winding is broken or burnt out. At the same time, check if the carbon brush of the motor is severely worn and needs to be replaced.

3. 檢查控制器和開關：如果電機本身正常，可能是控制器或開關故障導致電機不能正常工作。可以通過以下步驟進行檢查：

3. Check the controller and switch: If the motor itself is normal, it may be due to a malfunction in the controller or switch that prevents the motor from working properly. The following steps can be used for inspection:

a. 檢查控制器是否工作正常：使用萬用表或電壓表檢查控制器輸入輸出端口的電壓是否正常。如果沒有電壓輸出或輸入不穩定，可能是控制器故障，需要更換。

a. Check if the controller is working properly: Use a multimeter or voltmeter to check if the voltage at the input and output ports of the controller is normal. If there is no voltage output or unstable input, it may be a controller malfunction that needs to be replaced.

b. 檢查開關是否正常：檢查門的開關是否有松動或損壞情況。可以使用萬用表進行導通測試，確保開關正常工作。

b. Check if the switch is normal: Check if the door switch is loose or damaged. A multimeter can be used for conductivity testing to ensure that the switch is working properly.

如果以上方法仍然無法解決問題，建議聯系的維修人員進行檢修和維護。

If the above methods still cannot solve the problem, it is recommended to contact specialized maintenance personnel for inspection and maintenance.
