Gree: Frequency Guiji E1-E5E1: press overcurrent, overheating, excessive exhaust, module protection; E2: indoor anti-freeze protection; 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 pressure protection E4: compressor discharge temperature protection E5: over-current (low voltage protection) Principle: brass connections outside the machine has a high voltage protection switch, through 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 measuring 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, there 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 switching Then we can analyze the fault codes mean, generally faulty parts of this failure are: bad outdoor 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 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. Power error code E2: indoor pipe temperature control circuit, causing malfunction protection. 6. 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, available 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 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) 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 snapped the possibility of more than sixty percent, particularly in restaurants and other public places. 2 machine filter fouling, more than half of the possibility. 3 in the electrical and mechanical wind capacity is reduced resulting in lower internal fan speed. 4 machine evaporator back dirty, resulting in non-ventilated evaporator. 5 sensor resistance drift
