空调是我们生活中家家户户都有的家庭电器，而且空调的使用率非常的高，几乎在炎热的夏天每家每户都会打开空调，不过随着使用的时间的增加，很多的空调都会出现这样或那样的问题。如果空调在打开之后出现外机不转的现象该如何解决呢?
空调外机
空调打开外机不转—空调外机不转的原因
1, the remote control mode is not correct. Check the remote control settings are not cooling mode. Use air conditioning remote control, the mode is adjusted to show the "cooling" or "snow" state, the temperature set to 26 degrees or less.
2, power problems. Observe whether the outdoor unit has a working sound (including outdoor unit fans and compressors). If the outdoor unit fan is running, then the control circuit is basically normal. At this point should be observed whether the compressor starts, if the compressor is not started, you should check the power is normal.
3, the voltage causes. The voltage is not enough for many reasons here not to say, if the air conditioner can not boot, it is necessary to check whether the external power supply or voltage is not up to the rated voltage. If not the reason for low voltage, please check the indoor and outdoor connections are connected, the wire is aging, the indoor unit motherboard wiring is correct, or replace the motherboard.
4, a long time without maintenance. Air conditioning does not care for a long time outdoor air conditioner does not turn the specific outdoor air conditioner does not turn the reasons for the analysis, in the structure, the screw and the wind wheel may be locked loose parts; Improper; due to the injection molding process to ensure that the problem, the plastic pieces have a creaking sound, air guide bar and connecting rod mechanism are plastic parts, air guide strip, stepper motor and connecting rod structure of the transmission parts of the structure will be affected, will Cause the indoor unit does not work.
5, the ambient temperature is too high lead to system protection. Ambient temperature is too high, the sun is direct non-shady objects, poor outdoor ventilator hood or wall cover in front of the outdoor unit led to the air-conditioning heat blow out, the temperature is too high, the compressor automatically start the protection, stop working, to avoid compression Machine damaged.
6, AC contactor failure. The AC contactor, with a multimeter measuring AC contactor outlet, to see if there is 380V voltage, if not, then the AC contactor internal damage, the need to replace the new AC contactor.
1、遥控模式不正确。检查遥控器的设定是不是制冷模式。使用空调遥控器，将模式调整到显示“制冷”或“雪花”的状态，温度设定到26度或者26度以下。
2、电源问题。注意观察室外机是否有工作声音(包括室外机风扇和压缩机)。如果室外机风扇运转，则说明控制电路基本正常。此时应观察压缩机是否启动，如果压缩机未启动，则应检查电源是否正常。
3、电压的原因。电压不够的原因很多这里就不多说了，如果空调不能开机，就要检查外机电源是不是有电或者电压是不是达到额定电压。如果不是电压低的原因就请检查室内、外机连接是否接对，导线是否老化，室内机主板接线是否正确，否则更换内机主板。
4、长时间不保养。空调长时间的不保养会使空调室外机不转，具体空调室外机不转的原因分析，在结构上，可能是螺钉与风轮锁紧部位松脱;电机扁位与风轮配合部位配合位置不当;由于注塑工艺保证方面的问题，塑料件有吱吱的声音，导风条与连杆机构属于塑料件，导风条、步进电机与连杆机构结构的部位传动性能受影响，也会造成室内机不运转。
5、环境温度过高导致系统保护。环境温度过高、太阳直射无遮阴物体、室外机通风不良有网罩或墙体在室外机前方遮挡导致空调热量吹不出去，温度过高时，压缩机自动启动保护，停止工作，避免压缩机受损。
6、交流接触器故障。将交流接触器上电，用万用表测量交流接触器的出线端，看有无380V的电压，如果没有，则说明交流接触器内部损坏，需更换新的交流接触器。
空调打开外机不转—空调外机不转的解决方法
空调的蒸发器、冷凝器外部脏堵，都会使制冷效果明显下降，甚至出现不制冷现象，此种现象有些用户往往认为是缺氟，便送修理部修理，用户平时应该注意空调的定期清洗与保养工作。
拆下变压器，测量初级线圈无阻值，次级阻值正常，很显然，变压器初级线圈已经损坏，更换一个新的变压器后，接上电源，电源指示灯亮起，机器工作正常。
如果空调的种类不同则使用方法不同，空调的外机不转很有可能是我们的操作方法不正确所导致的。在夏天的时候都会开空调，如果大规模的电器用电可能就会导致电压不稳，如果电压不稳也会导致空调外机不转。以上就是空调外机不转的原因以及解决的方法大家可以进行参考。
