1、电机起不来

电机不能起动的二种原因，一种是六种可控硅的其中一只触发不可靠或是不导通，一相电路通过的是半波直流，电动机的两相绕组通过的直流对电动机起到了制动作用，不仅电机起不来，严重的还会烧毁电机和可控硅。二是启动参数或启动曲线不当导致电机起不来，这是最为常见的故障问题。

前者在使用中发生，但概率低于接触器的故障率。后者多发生在第一次运输调整中，调整后不再出现。大多数软启动器厂家的产品不会出现此问题，启动程序性能好，出厂价值设定适用性强。只有很少制造商的产品需要制造商自己调整。

2、可控硅烧毁

可控硅破坏或爆炸，这种故障与国内外品牌无关，但比接触器故障率低，主要问题出现在饼式可控硅的安装技术上。

3、控制器烧损

与软启动器相比，控制器烧损最严重。一些制造商出现这种故障，修理率超过30%。进口和合资制造商此类问题很少见，主要是控制器的电源和触发电路和输入电路三个部分容易烧毁。

4、软启动器误动作

电机在运行装置下软启动器受到干扰停止状态下，软启动器受到干扰启动时，前者普遍，后者只有两个品牌。造成误动作的主要原因，一是产品质量问题，二是与线路布局有关。

5、软启动器内部插件接触不良

软启动器内部插件的选择本来不是问题，这是国内制造商容易忽视的问题，故经常发生故障。
