What are the frequent failures after the air conditioning is transferred to the machine?

制冷系统故障是我们维修当中常风的故障，故障现象也是五花八门，千奇百怪，但还是有规律可循，有经验可借鉴。这里介绍的是空调制州苗木  保定电动门 保定空压机 化粪池模具 微型蠕动泵 保定强夯 收费岛模具冷系统故障的检查步骤，虽不是必须的，但是维修时应顺着此思路进行检修。

The failure of the refrigeration system is the common Wind fault in our maintenance. The failure phenomenon is also all kinds and strange, but there are still rules to follow and experience can be used for reference. Here is the inspection procedure for the failure of the air conditioning and refrigeration system. Although it is not necessary, maintenance should be carried out according to this idea.

一、制冷系统检修要点

1. The main points of the maintenance of the refrigeration system

1、观察内外机的工作情况：如指示灯板的显示情况，内机是否工作，风速输出是否正常，外机风扇、压缩机是否运行，从而判断是电器问题还是系统问题导致的不制冷。

1, observe the working conditions of the internal and external machines, such as indicating the display of the lamp board, whether the inner machine works, the wind speed output is normal, the fan and compressor run, so that it is the electrical problem or the system problem caused by the non refrigeration.
