如果以上测量结果表明模块基本没问题，可以上电观察。

(1) 上电后面板显示[F231]或[F002](MM3变频器)，这种故障一般有两种可能。常见的是由于电源驱动板有问题，也有少部分是因为主控板造成的，可以先换一块主控板试一试，否则问题肯定在电源驱动板部分了。(2) 上电后面板无显示(MM4变频器)，面板下的指示灯[绿灯不亮，黄灯快闪]，这种现象说明整流和开关电源工作基本正常，问题出在开关电源的某一路不正常(整流二极管击穿或开路，可以用万用表测量开关电源的几路整流二极管，很容易发现问题。换一个相应的整流二极管问题就解决了。这种问题一般是二极管的耐压偏低，电源脉动冲击造成的。

(3) 有时显示[F0022,F0001,A0501]不定(MM4)，敲击机壳或动一动面板和主板时而能正常，一般属于接插件的问题，检查一下各部位接插件。也发现有个别机器是因为线路板上的阻容元件质量问题或焊接不良所致。

(4) 上电后显示[-----](MM4)，一般是主控板问题。多数情况下换一块主控板问题就解决了，一般是因为外围控制线路有强电干扰造成主控板某些元件(如帖片电容、电阻等)损坏所至，我分析与主控板散热不好也有的关系。但也有个别问题出在电源板上。
