1. 檢查電源和電路：檢查電卷簾門(mén)的電源是否正常，并檢查電路連接是否松動(dòng)或短路。使用萬(wàn)用表或電壓表測(cè)量電源電壓是否穩(wěn)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(jī)本身：如果電源和電路正常，可能是電機(jī)本身出現(xiàn)故障?？梢酝ㄟ^(guò)以下步驟進(jìn)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(jī)是否正常運(yùn)轉(zhuǎn)：將電機(jī)直接連接到電源上，觀察電機(jī)是否能夠正常轉(zhuǎn)動(dòng)。如果不能轉(zhuǎn)動(dòng)，可能是電機(jī)內(nèi)部損壞，需要更換電機(jī)。

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(jī)繞組和碳刷：拆開(kāi)電機(jī)外殼，檢查電機(jī)繞組是否有斷裂或燒壞的情況。同時(shí)檢查電機(jī)的碳刷是否磨損嚴(yán)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(kāi)關(guān)：如果電機(jī)本身正常，可能是控制器或開(kāi)關(guān)故障導(dǎo)致電機(jī)不能正常工作?？梢酝ㄟ^(guò)以下步驟進(jìn)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(wàn)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(méi)有電壓輸出或輸入不穩(wěn)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(kāi)關(guān)是否正常：檢查門(mén)的開(kāi)關(guān)是否有松動(dòng)或損壞情況。可以使用萬(wàn)用表進(jìn)行導(dǎo)通測(cè)試，確保開(kāi)關(guān)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(wú)法解決問(wèn)題，建議聯(lián)系的維修人員進(jìn)行檢修和維護(hù)。

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