作为电动伸缩门系统的维修人员，除了具备电子器件应用的相关知识和电子电路分析能力外，还必须在实际工作中不断探索创新，善于总结总结，逐步提高逻辑分析和维修技能。
As a maintenance personnel for the electric telescopic door system, in addition to possessing relevant knowledge of electronic device applications and electronic circuit analysis capabilities, they must also continuously explore and innovate in practical work, be good at summarizing and gradually improve logical analysis and maintenance skills.
伸缩门维修中常用的基本方法可以概括为：询问、查看、倾听、触摸和测试。以下是逐一解释，以供参考。
The basic methods commonly used in the maintenance of telescopic doors can be summarized as: asking, viewing, listening, touching, and testing. The following are explanations one by one for reference.
一问：那就是询问。在与客户沟通时，首先询问型号、产品名称、损坏原因、故障现象，然后在此基础上进行详细分析，以达到有针对性、有针对性的处理，少走弯路。
One question: That's asking. When communicating with customers, first inquire about the model, product name, cause of damage, and fault phenomenon, and then conduct a detailed analysis on this basis to achieve targeted and targeted treatment, and avoid detours.
主要询问内容包括：何时损坏、是否被淹没、是否被击中、电压是否过高、是否被改装、是否操作不当、是否被雷击、是否有烟雾、是否有异响等。
The main inquiry content includes: when it was damaged, whether it was submerged, whether it was hit, whether the voltage was too high, whether it was modified, whether it was operated improperly, whether it was struck by lightning, whether there was smoke, whether there was abnormal noise, etc.
只有在询问原因后，才能确定下一步的维修方法和处理措施。对于雷击、浸水、冒烟、保险丝烧断等故障型号，不要贸然开机测试，否则会导致机器再次损坏，故障扩大。
Only after inquiring about the reason can the next repair method and handling measures be determined. For faulty models such as lightning strikes, water immersion, smoke, or blown fuses, do not hastily start the machine for testing, otherwise it may cause further damage to the machine and the fault may escalate.
二看：打开伸缩门控制壳后，仔细观察电路板上是否有部件损坏。
Second look: After opening the telescopic door control shell, carefully observe whether there are any components damaged on the circuit board.
如部件破损、黑黄头发、引脚碰撞、部件松动、接线错误等。经验丰富的维修人员会根据用户提供的相关信息和故障症状，准泥杆 保定古筝 塑料增韧剂 拱形护坡模具 保定空调维修  托辊生产线确检查伸缩门的可疑部件，并快速识别故障位置。
Such as damaged components, black and yellow hair, pin collisions, loose components, wiring errors, etc. Experienced maintenance personnel will accurately inspect suspicious components of the telescopic door and quickly identify the fault location based on the relevant information and fault symptoms provided by the user.
