案例一、遥控器接收器坏故障现象：遥控不开机原因分析：检查遥控器，用遥控器对准普通收音机，按遥控器上的任何键，收音机均有反映，说明遥控器属正常，故障在室内机主控板或者遥控接收器。

打开室内机外盖，检查220伏输入电源及12伏与5伏电压均正常，用手动启动空调，空调能正常启动运转，说明主控板无问题，故障部位在遥控接收器元器件上，经检查，发现原因在于控制器接收回路上瓷片电容(103Z/50v)绝缘电阻偏小，只有几kΩ，质量好的瓷片电容应该在10000MΩ以上,漏电电流偏大而引起的遥控不接收。

详细介绍》》解决措施：将103电容直接剪除或更换显示板后，空调器一直运转正常。

经验总结：造成不接收遥控信号的原因很多，除上述电容漏电外，无件虚焊也会造成不接收，另外空调使用环境对遥控接收影响很大，当环境湿度高时，冷凝水在遥控显示板背部焊接点脚与脚凝结，线路板发霉，绝缘性能下降，焊点之间有漏电导致遥控不开机或遥控器失灵，清洁线路板，用吹风机干燥处理后，在遥控显示板背部焊接一层玻璃胶，遥控能够正常接收。

用收音机AM档可检测遥控器是否发射信号，如手动开机后空调运行正常，可以排除主控板故障，由此可确定问题出在接收器，维修时不能简单地更换配件，尤其是短期内重复维修时，应仔细分析一下配件损坏原因。

案例二、室内风机关机后不停及未开机风机就运行故障现象：关机后，室内风机不停、未开机风机就运行。

原因分析：根据用户反映故障现象，通电即发现室内风机运行，用遥控开机后关机，室内风机仍在运行，初步判断为室内电机供电故障，检查室内风机供电电压，通电状态或关机装态下电机上有158V电压输出，因此通电后室内电机就运行，由此判定为风机控制可控硅损坏。

详细介绍》》解决措施：更换同型号控制器后试机正常。

经验总结：分体挂机室内机风机转速是由可控硅来控制的，当电源电压较低或波动较大时，会造成可控硅单相击穿，停机或关机时室内风机仍有电压，室内风机不能关闭。

案例三、空调不制冷、通讯故障故障现象：室内机“运行”灯闪（其余灯灭），内外机不工作原因分析：根据用户反映的情况，开机工作正常，未出现用户反映的情况，但大约30分钟后，内外机停止工作，控制面板上运行灯闪烁，按任何键空调都没反应，拔掉电源重新试机，机器能正常工作，但30分钟后又出现同样故障，因停机之前空调制冷正常，因此系统上不会存在问题，初步判断为外界信号问题，从公司提供的故障显示代码上也可以断定是通讯故障，测量内外机信号连接线正常，因此外界信号干扰问题。

•日立故障排查与操作办法：遥控开机或手按柜机面板按键空调无反应，室内机指示灯或显示屏不亮；①建议用户首先检查一下家中的配电箱上的电源开关是否跳闸，或电源插座与空调电源插头是否接触良好，确定是否有电；②建议用户将空调电源断开5分钟以上，（电源插头或电源开关断开）再将同空调电试机观察是否正常。

③检查遥控器内的电池是否无电容量、（观察如果按遥控器一瞬间遥控器上的显示屏字符立即很暗淡或消失了说明电池没有电量了）、电池是否在电池仓内与弹簧夹接触良好、电池是否报废泄漏电解液应清除干净、或遥控器出现显示屏上乱码“死机”操作失灵现象，应按遥控器上的“复位键”或用类似牙签的物件，将遥控器的“复位按键”按一下进行复位后，再重新开启空调观察，或将遥控器的电池取出5分钟以上后，再装入遥控器的电池仓内一试。

④如果用户按以上原因进行排查后，故障依旧，联系空调售后服务报修•空调室内机出现漏水故障原因？故障排查与操作办法：空调室内机漏水故障处理办法：观察室内机漏水故障产生具体部位后进行处理■ 室内机漏水故障原因有：①在天气温度过高和空气湿度接近饱和的情况时，是否将空调遥控器设定为除湿模式运行，因在除湿运行时，空调达到设定温度后会按照电脑程序在低于设定温度以下间歇开机10分钟和停机6分钟继续除湿（实际上相当于深度制冷运转，在空气湿度高于70度以上时，就会使室内机里产生大量的冷凝水）建议用户将空调设定制冷模式运行改善凝露过多造成的滴水故障；②用户反映导风板上向下滴水时，建议用户将空调设定导风板角度在水平或以上送风为宜。

③其他原因：用户将排水管是否在室内或室外部分由压瘪或弯曲上翘现象不能正常排水。

(Maintenance and inspection)•Clean the drain pan periodically. The drain pipes clogged with dust will cause water leakage.•For cleaning, consult with your Daikin dealer. (Before each season when cooling or heating is required, clean the air handler.)•If the area around the indoor unit is very dusty, use a dust proof cover (local procurement).(Cleaning the inside of the indoor unit)•It is necessary to clean the inside of the indoor unit peri-odically.Since the cleaning requires special technologies, requesta Daikin dealer to clean them.(Electric heater replacement interval)•The electric heater should be replaced every ten years.This replacement interval is a guideline for ensuring safe and trouble-free operation of the product for many years. (Cleaning the air filter)•The air filter is an optional accessory.EXPLANATION:•Removing the air filter except when cleaning the air han-dler may result in accidents.•Replace the filter when one of the following messages displayed on the bottom of remote controller screen.- Time to clean filter & element- Time to clean filter•If using the air handler under very dusty environment, increase the frequency of air filter cleaning.•Reset the filter sign on main menu of remote controller.Refer an operation manual of remote controller for de-tail.•Consult dealer to change filter setting time to display fil-ter change alarm on remote controller screen. (The de-fault factory setting is 2500 hours.)•There are the following time, display pattern: 1250, 2500, 5000, 10000.•Do not allow the indoor unit to get wet as it may cause an electric shock or fire._______________________________________________ 4. PRECAUTIONSIf the following phenomenon occurs, contact your dealer.•Any abnormalities in the operation of the heat pump or air handler such as smoke or fire could result in severe injury or death.Turn off the power and contact your dealer immediately for instructions._______________________________________________ Phenomenon•The unit may operate with the airflow rate at high speed even though the airflow rate was set to low speed using the remote controller during ELECTRIC HEATER opera-tion.Take the following actions before contact.Check to see if an optional electric heater is installed.The unit operates with the airflow rate at high speed dur-ing ELECTRIC HEATER operation regardless of the re-mote controller airflow rate setting or display.Phenomenon•The safety devices such as fuse, breaker, ground fault interrupter, etc. often operate or operations of the opera-tion switch are unstable.Take the following actions before contact.Turn off the switch.•If the ON/OFF switch does not properly work, Take the following actions before contact.Turn off the main power switch.Phenomenon•Water leaks out from the air handle r.Take the following actions before contact.Stop the operation.Phenomenon•Error message is displayed.
