二、维修注意事项（部分控制元件故障分析）1、室内部分①环境感温包开路：整机制冷时不启动或启动一下就停机；制热时工作正常，且一直是高频运转。

②管温包开路是：分体机和灯箱柜机，容易出现工作6分钟至10分钟就停外机，液晶显示的会显示E2并停止室外机。

③管温包短路时：制冷是无防冻结保护外机不启动；制热是无防高温保护，整机停止工作。

④所有温控元件阻值有偏差时，频率会一直出现高频不降频或是一直低频不上升。

（有些温控元件在不通电的情况下阻值正常，最好是通电检查。

）三、室外部分①压缩机过热保护器，当其出现保护时:停室外机，外机主板指示灯闪烁且长时间开不了机。

②室外化霜管温头开路时：制冷正常：制热时会45分钟就化霜一次，10分钟解除化霜，反复循环。

③室外化霜管温短路时：制冷制热均不会工作。

④室外机环境感温包开路时：对空调机运转不受影响。

⑤室外机环境感温包短路时：制冷时不受影响，制热时空调一直低频运转，频率不上升。

⑥压缩机排气口感温包开路时，空调机运转一直处于高频（不会降频）。

⑦压缩机排气口感温包短路时：制冷制热均开不起机。

⑧变频器（模块）的故障判断及更换a、开机后测量p+、N－之间是否有300V左右的直流电压b、检查+5V与+12V输出是否正常，可以在室外机找点测量c、如（a）和（b）正常之后，检测U、V、W三相是否有平衡交流电输出。

（在检测U、V、W之间电压时，最好是将压缩机连线拆下检查）d、如（a）、（b）、（c）都正常之后，检查压缩机线圈阻值是否正常。

（压缩机三个端子阻值是否相等，阻值应为1～3欧姆。

）e、模块更换及安装时，必须要涂散热膏，螺丝要均衡拧紧，紧贴散热膏，否则温度过高，出现模块频繁保护，压缩机频繁开停。

f、室外主控板与模块之间的10根通讯线一定要小心插紧，控制器上的+5V与+12V 均都由模块输出。

10根通讯线其中三根分别为：地、+5V、+12V另外7根是数据线，需用示波器方能检测。

⑨室外机两个整流桥，一个为220V输入，输出300V直流至模块p+与N－两端：另一个是半波整流滤波作用。
