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。还有一种是插电有蜂鸣声，遥控不泥杆 保定空压机 保定古筝 塑料增韧剂 拱形护坡模具 保定空调维修 托辊设备 托辊生产线开机【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】
1. There are two main types of air conditioner not starting up. The first is that there is no response when it is powered on. [transformer, fuse and rectifier bridge] these should be the things of Pediatrics. The important measurement voltage such as 5V is normal. Most of these problems can be solved by changing the crystal oscillator [next to the CPU]. There is also a beep when plugged in and the remote control is not turned on [manual operation is OK] it is basically that the receiving head is broken [change the receiving head and don't search online. It's easy to find the anchor of the receiving board. It's easy to find the negative pole of the capacitor or the line with a wide circuit board. It's easy to find the other two pins of the anchor]
2. The air conditioner automatically switches on and off from time to time. Some call in the middle of the night. Cleaning the receiving board, changing the receiving head or removing the automatic transfer switch can basically kill.
