1、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)Gree:FrequencyGuijiE1-E5E1:pressovercurrent,overheating,excessiveexhaust,moduleprotection;E2:indooranti-freezeprot

3、sureprotectionE4:compressordischargetemperatureprotectionE5:over-current(lowvoltageprotection)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，
4、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。E1isasystem-voltageprotection.FaultPrinciple:brassconnectionsoutsidethemachinehasahig
