      <description><![CDATA[空调维修,第1个细节:有名片吗?
很多空调维修人员,一般都是接到客户报修电话,去了客户那里,修好了就走。这样一来，客户下次怎么找到你？ 
好的做法是，不管你的公司或者维修店老板，有没有给你印名片，自己给自己印个名片吧，一包香烟的价格...

      <description><![CDATA[空调电路板CPU芯片检修方法：因为空调CPU正常工作的必要条件为：电源电压+5V、复位电压、时钟脉冲信号，这三个条件缺一不可，否则CPU就不能正常工作。所以，可用万用表检测其工作条件的电压，若电压值正常，整机不工作，即可判断CPU芯片损坏。]]></description>

      <description><![CDATA[空调电路板晶振电路检修方法：通电开机，正常时用万用表测量石英晶振管的两脚电压为+2.2V左右。若小于1.5V，则为电路停振。别处，还可通过拆下石英晶振管，用万用表欧姆挡进行判断，良好的石英晶振管，用万用表测量应是开路的。如果发现短路，则表示晶体已损坏。对于开路 ...]]></description>

      <title>空调电路板复位电路故障检查与维修方法</title>

      <description><![CDATA[空调电路板复位电路检修方法：
复位电压是延迟上升的电压，可用万用表直流电压档进行观察，如果观察不清楚，还可用示波器检测，用示波器检测时可以有一条基线在抖动，然后变为高电平，这就是复位电压的启动过程。如果没有看到基线的抖动，则说明复位电路有故障。]]></description>

      <description><![CDATA[空调电路板继电器电路检修方法：
首先区分是集成功率驱动模块损坏或继电器损坏，如果开机按遥控器后，蜂鸣器有响声，但整机无工作，一般是集成功率驱动模块损坏；如果开机后，只是部分功能不 正常，就有可能是继电器损坏，此时可继续通过听继电器是否吸合声，来判断继电 ...]]></description>
