padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;">检查：除霜探头故障或（测量）冷媒含量是否缺少，或毛细管微堵、脏堵、冰堵。</span></span></span></span></p> <p helvetica="" neue="" style="margin: 15px 0px;

padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;">排除：更换除霜探头；充注同型号冷媒，必要时抽真空后再进行充注操作，清理毛细管。</span></span></span></span></p> <p helvetica="" neue="" style="margin: 15px 0px;

padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;">按显示面板的查询键，查询D03与D04环境与盘管探头的温度，与实际的是否相符，初部判断是不是机器没有化霜的问题。</span></span></span></span></p> <p helvetica="" neue="" style="margin: 15px 0px;

padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;">1、如果探头探测到与实际的环境和盘管探头的温度不相符可以认定为温度传感探头的问题，（故障率较高）</span></span></span></span></p> <p helvetica="" neue="" style="margin: 15px 0px;

padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;">检查：先检查显示板上面是不是有风机的符号然后再检查风机与主板的插头是否松动；用万用表测量主板上面的风机脚，是否有220V的电压，从这可以判断主板问题还是风机方面的问题。</span></span></span></span></p> <p helvetica="" neue="" style="margin: 15px 0px;

padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;">有电压的情况下基本上可以判断主机控制电路方面没有问题，然后重点检查风机的电容与电机的线圈方面的问题。还有轴承是否卡死，这个可以先用手去转一下风叶看是否顺畅</span></span></span></span></p> <p helvetica="" neue="" style="margin: 15px 0px;
