1、格力空调维修空调错误格力： 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: Frequency Guiji E1-E5E1: press overcurrent, overheating, excessive exhaust, module protection; E2: indoor anti-freeze protection;

2、E3: indoor temperature thermal package open, short circuit; E4: indoor pipe temperature open, short circuit ; E5: indoor and outdoor communication failure. : Fixed-frequency machine fault codes: E1: Compressor high pressure protection E2: Evaporator anti-freeze protection E3: compressor and low pres

3、sure protection E4: compressor discharge temperature protection E5: over-current (low voltage protection)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

4、、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。E1 is a system-voltage protection. Fault Principle: brass connections outside the machine has a high voltage protection switch, through

5、 the high pressure switch detects the system pressure, then back to the chip via lines. Maintenance procedures: 1. First rule out external factors, such as evaporators, condensers dirty, lack of equal power. If the machine displays a boot on E1, to see if the compressor is started, if not start meas

6、uring high voltage switch, if the measured start the compressor starting current. 2. Machine open for some time to display E1, check the high voltage switch, and line. High-voltage switch can be shorted or OVC shorted somewhere exclude failures.E1: high-voltage protection for the compressor. 1, ther

7、e is an obstacle before the condenser 2, when the outdoor temperature is higher than 43 degrees start cooling 3, the control circuit anomaly 4, the high-pressure pipe pressure Ambassador high voltage switchingThen we can analyze the fault codes mean, generally faulty parts of this failure are: bad o

8、utdoor unit heat, can be cleaned. Slow outdoor fan does not turn or turn: decision solution method, for the fan, the fan capacitor. High pressure protection fault: Solution, refrigerant excessive, high-voltage protection is damaged, the signal line is broken or damaged indoor control board.E2：室内机蒸发器

9、防冻结保护。可能原因：故障代码E2：第一步先判断是控制故障还是系统故障，可先把室内管温包从蒸发器中取出，如果不出现，则说明是系统问题；第二步检查室内环境温度是否太低，室内风机转速是否太低，室内蒸发器是否太脏，系统是否堵塞。5. 开机显示故障代码E2：室内管温器断路，造成误保护。6. 运行一段时间压缩机、室外风机停止，室内风机仍运转，显示故障代码E2（灯箱型无显示）：（1） 检查蒸发器是否结霜，若结霜，则显示故障代码E2。其结霜原因可能是： 1) 系统缺氟，可用压力表测系统压力、用钳表测运行电流，低压偏低或电流偏小，则需加氟。 2) 气温偏低（25以下）时，制冷运行蒸发器可能会结霜。 3) 蒸发

10、器表面脏，风量小。（2）如蒸发器未结霜，则可能是室内管温头位置不对，造成局部温度过低，可将管温头移出再试。（3）室内管温感温包坏或折断。（4）也可能是显示器本身故障或控制板问题。（5）过滤网太脏。（6）系统脏堵。（7）室内电动机转速太低。E2: indoor evaporator anti-freeze protection.Possible causes: Error code E2: the first step is to determine fault or control system failure, the indoor pipe temperature can first be

11、 removed from the evaporator package, if you do not appear, the problem is the system; the second step is to check the ambient room temperature too low, the indoor fan speed is too low, the indoor evaporator is dirty, the system is blocked. 5.

Run a period of time of the compressor, outdoor fan stops, indoor fan is still running, error code E2 (light boxes without display) :( 1) Check whether the evaporator frost, if frost, the error code E2. Its frost reason may be: 1) lack of fluoride system, ava

13、ilable gauge pressure measurement system, measured with a clamp operating current, low-voltage low or current is too small, you need fluoride. 2) low temperature (25 or less), the cooling operation may evaporator frost. 3) evaporator surface is dirty, the small amount of wind. (2) If the evaporator

14、is not frosting, it may be the indoor pipe temperature head position is wrong, resulting in local temperature is too low, you can head out of the tube temperature and try again. (3) Indoor pipe temperature, temperature of bad or broken. (4) may also be a display fault or the board itself issues. (5)

15、 The filter is dirty. (6) The system fouling. (7) Indoor motor speed is too low.制冷过负荷保护，即内机蒸发器结冰了，原因：1 老鼠把传感器线咬断可能性在百分之六十以上，特别是饭店等公共场所。 2内机滤网脏堵，可能性一半以上。 3 内风机电容量减小导致内风机转速低。4内机蒸发器后背太脏，导致蒸发器不通风。5传感器阻值漂移Cooling overload protection, namely the machine evaporator freeze up because: 1 mouse sensor wires s
