空调不制冷的原因有很多，我们在检查空调为什么不制冷的时候首先需要检查空调的电源是不是插好了，空调的接头和电源是否存在接触不灵的状况。要是空调的没有接通到电源当然就会出现不制冷的情况了。
A. There are many reasons why the air conditioner does not cool. When we check why the air conditioner does not cool, we first need to check whether the power supply of the air conditioner is plugged in and whether there is poor contact between the connector and power supply of the air conditioner. If the air conditioner is not connected to the power supply, of course, there will be no refrigeration.
B、维修方法：空调的电源出现问题，就只需要将空调的电源重新的插好，保证空调能够正常的通电就可以了。
B. Maintenance method: if there is a problem with the power supply of the air conditioner, just plug in the power supply of the air conditioner again to ensure that the air conditioner can be powered on normally.
C、我们在检查了空调电源之后再来看看空调的电压是不是不稳地，或者是不够。空调的电压不稳定达不到空调的预定电压，就像人没有吃饱就干活一井盖钢模具 U型槽模具 天津水处理设备 检查井钢模具 保定公司注册 u型槽模具 流水槽模具 样，空调工作起来就会非常的吃力。一般会出现电压不稳的情况是在用电高峰期的时候。
C. After checking the power supply of the air conditioner, let's see if the voltage of the air conditioner is unstable or not enough. The voltage of the air conditioner is unstable and can't reach the predetermined voltage of the air conditioner. It's like working without food. The air conditioner will work very hard. Voltage instability usually occurs during peak power consumption.
D、维修方法：这在个时候空调出现不制冷的情况就不是我们能够用方法进行解决的情况了，我们需要从稳定空调电压这一方面入手。
D. Maintenance method: at this time, if the air conditioner does not cool, it is not a situation that we can solve with methods. We need to start with stabilizing the air conditioning voltage
