空调错误

格力：变频柜机E1-E5E1：压机过流，过热，排气过高，模块保护；E2：室内防冻结保护；E3：室内温度感温包开，短路；E4：室内管温开，短路；E5：室内外通讯故障。：定频机故障代码：E1：压缩机高压保护E2：蒸发器防冻结保护E3：压缩机低压保护E4：压缩机排气温度过高保护E5：过电流（低电压保护)

E1是系统高压保护。故障原理：外机铜管连接的有个高压保护开关，通过高压开关检测系统压力，然后通过线路反馈给芯片。维修流程：1.首先排除外界因素，如蒸发器，冷凝器脏，电源缺相等。如果机器一开机就显示E1，看压缩机是否启动，若没启动测量高压开关，若启动测压缩机启动电流。2.机器开一段时间显示E1，检查高压开关，和线路。可以短接高压开关或OVC短接，排除某处的故障。

E1:为压缩机高压保护。1、冷凝器前有障碍物2、室外环境温度高于43度时开始制冷3、控制回路异常4、高压管压力过大使高压开关动作

那么我们可以根据故障代码含义来分析，一般出现此故障的故障部位为：室外机散热不良、清洗即可。室外风机不转或转的慢：决解方法，换风机、风扇电容器。高压保护故障：解决方法，雪种过多，高压保护器损坏、信号线断或室内机控制板损坏。
