    检查电动伸缩门不能正常伸缩的原因:
    Check the electric telescopic door can't normal scale:
    首先检测电动伸缩门有没有电电、保险管有没有烧毁,济南玻璃门检测遥控器是否还有点,必须要做全面检查。排除故障对应处理。
    First test electric telescopic door have electricity, insurance tube have burned, detect whether there are some remote control, have to do a comprehensive inspection. Troubleshoot the corresponding processing.
    电机线、信号线良好,还是不能开关,说明控制盒有故障。为什么不先换控制盒呢?如果有哪里出现短路,可能将刚刚换好的又会烧坏。所以,我们要检查好每个部位,没有其他故障隐患后,才可以更换。
    Good electrical lines, signal lines, still can't switch, control box is faulty. Why don't you change control box first? If there is a short circuit, may after a good will burn out. So, we must check every part, no other problems, can be replaced.
    电动伸缩门电机引线只有红、黄相通,与白色分别不通,查看电机定子是否发烫,若发烫厉害,说明电机热保护停机不能开关。若不发烫,检查20UF的启动电容是否失效。

    Electric telescopic door motor lead only red, yellow, and white, respectively, to check whether the motor stator hot, if hot, motor thermal protection downtime cannot switch. If he is not hot, check whether 20 uf startup capacitor failure.
