Reasons and solutions for Gree inverter air conditioner to display E6**:

1. The reason for the failure of Gree air conditioner E6** is that this situation will occur when the air conditioner encounters a crash, because the air conditioner cannot operate normally after the crash, resulting in the failure of the air conditioner, so in this case, it is recommended to cut off the power supply of the air conditioner and wait for a period of time, and then turn on the test run.

2. There is also a kind of E6** failure because of the long-term use of Gree inverter air conditioner and the particularly bad environment, the internal dust accumulation is too much, which can cut off the power supply of the air conditioner, and then open the panel of the air conditioner to clean the dust inside, this cleaning procedure needs to be operated regularly, so as to not only reduce the appearance of air conditioning failure, but also keep the cooling and heating effect of the air conditioner in the best state.

3. Check whether the power cord of the air conditioner communicates normally, because the indoor unit of the air conditioner and the outdoor unit are always connected, if one party fails, the other party will be the other, so check whether the connection line between the indoor unit and the outdoor unit is in poor contact or damaged, if it is caused by poor contact, it is recommended to re-fix it, if it is not a problem with the connecting wire, it is recommended to ask a professional home appliance maintenance master for inspection and maintenance.

The main board of the outdoor unit is damaged, resulting in an alarm for air conditioner failure;

If the communication failure of indoor and outdoor units fails, you can check whether the signal line has problems such as short circuit or open circuit;

The circuit of the main control board of the indoor unit is abnormal, resulting in an air conditioner fault alarm;

If there is a power supply problem with the fan motor of the outdoor unit, or it is damaged, the fan motor of the outdoor unit needs to be checked.

The frequency conversion module of the outdoor unit conflicts and protects, causing alarm failures;

The compressor of the outdoor unit is overloaded, resulting in protection shutdown;

Refrigerant leakage, resulting in a protection alarm;

The power supply of the outdoor unit is insufficient, causing an alarm;

Solution: Replace the signal connection cable of the internal and external machine;

If the fault is not solved, it is necessary to measure the power supply voltage of the signal port of the external computer board, if there is a voltage, it means that the communication is fine, and the fault may be caused by the self-conversion motherboard or module;

The power supply voltage of the signal port of the external test board is about 0V-1V, which means that the control circuit board of the indoor unit is abnormal, and it will be replaced and then tested;

If the inverter module of the outdoor unit is overheated or the power supply voltage is abnormal, it proves that the module has a problem and needs to be replaced.

If the speed of the outdoor unit is unstable, it means that the external fan is abnormal, and it should be replaced and tried again.

If the outdoor fan does not work, the compressor will stop when it starts, and E6 will be displayed, indicating that the main control circuit board of the outdoor unit may not supply power to the external fan, and you need to check the thyristor, relay or replace the main board of the external unit to try again;

The above is the possible reason for the appearance of Gree air conditioner E6**, after the appearance of E6, users should seek after-sales help as soon as possible, this kind of professional maintenance work, try to let the after-sales maintenance.

It is a function of the Gree air conditioner.

An automatic, intelligent function that adjusts itself according to changes in the surrounding environment.

Question: I changed the motherboard of the internal machine, and still came out of E6

Which line is loose?

Answer 1, the failure of E6 in the fixed frequency cabinet machine ** means that the electrostatic precipitator itself or the connection line is damaged, and whether there is too much dust on the surface; 2. The fault of E6 in other commercial cabinets means that the communication signal between the indoor unit and the outdoor unit is abnormal, and the power supply cannot be added to the outdoor or outdoor unit control motherboard, so it is necessary to check whether the connection line between the indoor unit and the outdoor unit is mismatched or in poor contact, and pay attention to check whether the phase wire and the neutral line of the power supply line of the air conditioner are reversed.

1. The motherboard of the outdoor unit is broken.

2. For indoor and outdoor communication failures, mainly check whether the signal line is short-circuited or open-circuited.

3. Conflict and protection of the outdoor unit frequency conversion module of Gree inverter.

The appearance of Gree inverter air conditioner E6 is caused by the poor thermistor of the indoor unit heat exchanger, this resistance needs to operate in a normal temperature environment, if it works poorly, it may be that the indoor unit filter of the air conditioner is too dirty, resulting in cold air blowing into the position of the electric annihilation, blocking the ambient temperature is abnormal, and cleaning the air conditioning filter can be done, and the specific operation steps are as follows:

1. Turn on the air conditioner panel.

2. Pull and hold the air conditioner filter.

3. Remove the air conditioner filter.

4. Clean the air conditioner filter.

Precautions: 1. Operate gently, do not damage the plastic parts.

2. Do not touch the internal fan.

Gree inverter air conditioner E6 fault, this fault is relatively hidden, not easy to find.

Analysis of the causes of Gree air conditioner E6 failure:

1.If the communication fails, check whether the black cable with the outdoor unit is loose. If not, look for after-sales maintenance.

2.If H6 is displayed, it is the motor stalled or the motor does not rotate fault.

It means that your internal unit is too dirty. Turn off the main power, open the lower cover, and pull out the filter screen for cleaning; Clean that electrostatic precipitator with a brush.

Maintenance technology of Gree inverter air conditioner.

1) Plug in the power plug, the power indicator of the indoor unit is on, if there is no power indication, it means that the power supply of your home is faulty or the indication is damaged.

2) There is a power indication, press the operation button with the remote control, and the signal cannot be transmitted. First of all, check whether the battery in the remote control has electricity, and then check whether the positive and negative electrode contacts of the battery have oxidation corrosion, if the above is normal, check whether the internal circuit board of the remote control is damaged, you can use the remote control * near an AM radio, press the remote control key for interference test, listen to whether the radio emits a "beep" sound, and the sound indicates that the remote control is not faulty.

3) When the remote control determines that there is no fault, the signal still cannot be transmitted, it can be verified by the forced operation switch of the indoor unit, and when the indoor through-flow fan and outdoor compressor are running normally and the refrigeration effect is good, it proves that the infrared receiving part of the indoor unit of the air conditioner is faulty.

4) When the remote control you use is installed with a new battery and does not display for less than a month, you can open the back cover of the remote control, clean the conductive film on the circuit board and key contact surface with 95% alcohol, and after drying, you can eliminate the leakage fault, and the remote control LCD display is missing words can also be used in this way.

5) The temperature sensor in the inverter air conditioner plays a very important role, and the indoor unit has an air temperature sensor and an evaporator temperature sensor; The outdoor unit has air temperature sensors, high-pressure pipeline sensors and low-pressure pipeline sensors, and some sensors change the resistance value after long-term use, so that the control characteristics change, (such as the resistance value of the indoor unit air temperature sensor becomes larger, it will cause the output frequency of the inverter to be low), in order to ensure the control accuracy, and its same working characteristics, after determining the sensor failure, the original model of the product should be replaced.

6) When the air conditioner fails, if the whole control system is faulty, the switch on the indoor unit controller can be placed on the "trial run" gear, at this time, the microprocessor will send a signal with a frequency of 50Hz to the inverter, if the air conditioner can run at this time, and keep the frequency unchanged to work, it is generally believed that the whole control system has no major problems, and the sensors can be checked to see if they are in good condition. If the air conditioner is not functioning properly, the control system is faulty.

Gree air conditioner shows E6, and the fault is: communication failure. It is estimated that your air conditioner is inverter, and there are several possibilities:

1. The wiring of the internal and external units is wrong (if your air conditioner has been used for a period of time before E6 appears, then the first point is to eliminate); Second, the motherboard of the internal machine is broken (this possibility is relatively small); 3. The outer board is bad (there are several possibilities for the outer board to be broken, the temperature of the K tube is bad, 2. There is no voltage); Fourth, the signal connection line is broken. Hope it helps.

Dear, hello, I am glad to answer for you that the Gree inverter air conditioner appears E6 is 6 is a communication failure, the indoor unit is generally displayed as the running light flashes, the air conditioning status is refrigeration when the compressor stops, and the internal fan works; When heating, the compressor and the internal fan are stopped. In general, this problem occurs 1: when installing, the connection pipeline between the indoor unit and the outdoor unit is not long enough, and the extension pipeline is long, and there will be problems at the joint of the extended link line, resulting in a short circuit between the indoor and outdoor connection lines; 2 You check the power supply of your home The general air conditioner hangs up is a 16A three-phase socket The top is the bottom line jack The left zero wire jack The right is the live wire jack You use an electric pen to detect whether it is the connection of the left zero and the right fire, and the cabinet above 2p is equipped with a leakage protection switch Generally 32A 60A 63a This should be selected according to the size of the air conditioner The leakage protector is also connected to the left zero and right fire I will briefly talk about the reason: because now in order to prevent lightning strikes and other elements Will be grounded wire, if the fire zero wire is reversed, there will be communication failures from time to time, I have encountered it before; 3. If the above two situations cannot be solved, then it should be a problem with the circuit board of the outdoor unit, and this should be tested by professionals, hoping to help you. Thank you.
