1、空调不开机，不开机主要有2种，第一就是上电没有任何反应，【变压器，保险管，整流桥】这些应该是小儿科的事情，重要的测量5V等电压都正常这种问题大部分换晶振【就在CPU旁边的】可以解决。
1, air conditioning don't boot, boot mainly has two kinds, the first is no reaction, the transformer, insurance tube, rectifier bridge 】 【 should be a pediatrician, important measure 5 v voltage all the problems, such as most in crystals is next to the CPU of 】 【 can be solved.

 
还有一种是插电有蜂鸣声，遥控不开机【手动可以】基本就是接收头坏【换接收头不会再网上搜下就知道，找接收板的地脚很容易吧，电容的负极或者电路板很宽的那条线，找到地脚其他两脚就很容易哦】
And there's a plug with hum, remote boot basic manual can 】 【 is not receiving head bad [in receiving head won't knew the search on the net, looking for receiving plate anchor easily, capacitance of the cathode or the line of PCB is very wide, it is easy to find the anchor other two foot.

 

 
2、空调不定时自动开关机，有的半夜叫，清洗接收板，换接收头或者拿掉自动转换开关基本可以通杀。
2. The air-conditioner is not timed automatically, and some midnight call, clean the receiving board, change the reception head or remove the automatic switch switch to basically kill.

 

 
3、开机几分钟或者数十分钟外机自动停机，或者外机不启动换室内管温传感器。
3. The machine will automatically stop for a few minutes or tens of minutes, or the external machine won't start the room temperature sensor.

 

 
4、开机显示各种故障代码，呵呵呵，想必你无法记住所有的空调代码吧，本人从不记故障代码，教你绝招，1测内外机连接线。2测传感器.3测电源电压.4换向【380V电】，查是否掉相.
If you can't remember all the air conditioning code, I never memorized the code of failure. I will teach you the best way to do it, and 1 test the connecting line of the inside and outside machine. 2 sensor. 3 power supply voltage. 4 change to [380V power], check whether the phase is falling.
观察电流和室内外机是否过脏，相信一般问题都可以解决。
Observe whether the current and indoor and outdoor machines are dirty, and believe that general problems can be solved.

 

 
5、开机室外机不启动或者外面只有风扇转，对于初学者一般是电容坏，其他问题再具体分析。
5. When the machine is not started or the fan is turned outside, it is usually a capacitor for beginners, and other problems are analyzed in detail.

 

 
6、开机一段时间压缩机热保护，相信这是所有维修空调的最头痛的问题，这种问题按常规办法解决不能正常的，确认系统和电压散热正常的情况下，最好换压缩机，别浪费时间，时间就是金钱，别听有些杂志说的一大堆方法，那些方法我都用过，成功率很低，没有必要，有的人改短毛细管，千万不要怎么做，职业道德问题，而且影响空调效果。
6, boot compressor thermal protection for a period of time, believe that this is the most headache problem in all maintenance of air-conditioning, this problem is solved by conventional method can not be normal, cooling system and the voltage is normal, the best in the compressor, don't waste your time, time is money, don't listen to some magazine said a lot of methods, I used the method, the success rate is very low, there is no need, to shorten the capillary, some people don't do, professional ethics problems, and affect the effect of air conditioning.

 

 
7、还有就是一插电就显示故障代码和运行后显示故障代码是不一样的，插电显示一般是电源或者信号线，主板问题。运行一段时间显示一般是传感器问题。
7. There is also a plug-in that shows that the fault code is not the same as the failure code after the operation. The plug-in display is usually the power or signal line, the main board problem. Running a period of time is usually a sensor problem.

 
空调感温头故障维修技巧
Air conditioning temperature head failure maintenance skill

 

 
由于温度传感器(俗称感温探头)的阻值，在不同的温度，对应不同的阻值，并且元件本身没有任何厂家的型号和参数标识，这给我们维修空调时增加了判断难度。常常在网上看到一些朋友发感温头的帖，这里有一些技巧，可帮大家解决这样的问题。
Due to the temperature sensor (commonly known as thermal probe) resistance, in different temperature, corresponding to different value, and the element itself there is no factory model and parameter identification, it is harder to determine when maintenance air conditioning to us. I often see some friends on the Internet with a warm head post, here are some tips to help you solve such a problem.

 
一般同行在维修过程中是以实测阻值和资料对比，或者用手握感温头，用表测其阻值是否有变化来判断其好坏。这些可以大概判断出传感器的好坏。不过有些传感器，在用加温法时，阻值也是变化的，但其阻值已经严重偏离正常值.还有些机型不熟悉，无法知其确定的阻值。本人观看许多空调的电路图发现，空调的传感器电路基本相似，都是以电阻分压形式提供信号电压给CPU进行比较计算，以此判断外界温度的高低。CPU向感温头供电一般是+5V，经过感温头电阻变化分压后，输入CPU的电压一般在+2.0V~3.0V之间，这也是传感器两头的电压。如果测出的电压严重偏离，可判断传感器已经损坏。
In the process of maintenance, the average peer is measured against the measured resistance and data, or the temperature of the hand is used to determine whether the resistance is good or bad. These can presumably determine the quality of the sensor. However, there are some sensors, which are also changed when using the heating method, but the resistance value has been seriously deviated from normal value. Some models are not familiar and can not be determined. I watch a lot of air conditioning circuitry found that air conditioning is similar sensor circuit, are provided in the form of partial pressure resistance signal voltage comparing to the CPU computing, to judge the outside temperature. When the CPU is supplied to the thermal head, it is usually + 5V, and the voltage of the input CPU is normally between + 2.0v ~ 3.0v after the differential pressure of the sensor, which is also the voltage at both ends of the sensor. If the measured voltage is seriously deviated, it can be judged that the sensor has been damaged.

 
1、不同类型感温头的阻值不同，但如何判别感温头的好坏呢?很简单，就是在线测量它的电压，25度时正常的电压一般是在+2~+2.5V之间。
1. Different types of temperature head have different resistance values, but how to judge the quality of the temperature head? It's easy to measure its voltage online, and the normal voltage at 25 degrees is usually between + 2 ~ + 2.5 V.

 
2、因为人的体温恒定，所以用手握感温头一时，它的在路电压是一定的(约为2.17V)。
2. Since the person's body temperature is constant, it is certain that it is in the road voltage at the moment of the hand grip.

 
3、拔掉感温头的插头，在线路测量其座子的两个插针的电阻，所得的阻值基本就是感温头在25℃时的型号值（经实际检验此方法不准确）。如果是8K左右的电阻，那传感器感温头的型号值一般是10K；如果是4.7K电阻，则是5K感温头；以此类推。但有部分大型空调，变频空调外机控制板温度传感器的阻值是下偏置电阻的3倍，即以上述方法测出的阻值乘以3，就是传感器在25°C 时的阻值。
3, remove the plug of the thermal head, the on line measuring the seat of the resistance of the two pins, the basic is the thermal resistance of head at 25 ℃ when the model value (after the actual test this method is not accurate). If the resistance is around 8K, the sensor temperature of the sensor is usually 10K. If it is 4.7 K resistance, it is 5K temperature head; And so on. But there are some big air conditioning, frequency conversion air conditioning machine control panel under the temperature sensor resistance is 3 times of bias resistors, i.e., according to the above methods to measure the resistance of 3 times, is the resistance sensor at 25 ° C.

 
4、感温头的型号值就是它在25℃时的电阻值，通常是5K，10K，15K，20K，50K这几种，一般都是负温度系数的，即温度越高，电阻值反而越小。
4, the model value of thermal head is its resistance value at 25 ℃, is usually a 5 k, 10 k, 15 k, 20 k, 50 k this several, are generally negative temperature coefficient, the higher the temperature, the smaller resistance instead.

 
5、一般来说内机管温和室温阻值是一样的。
5. Generally speaking, the temperature resistance of the inner tube is the same.
