Anonymous users2024-02-08Install Gredo online, all external machines display E6, E6 is a communication failure, there are 3 possibilities for analysis:
1. The signal line between the first machine and the outdoor unit.
2. There is no power supply for the outdoor unit.
3. Phase sequence of the external machine.
Meaning of fault **e6:
1. Communication failure;
2. Mode conflict;
3. Overlapping internal machine**;
4. Power failure of external unit;
5. The air conditioner crashes;
6. The signal line of the internal and external machine is broken or leakage;
7. The indoor circuit board is broken.
Repair method of fault **E6:
1. Check whether the indoor and outdoor communication signal lines are open or short-circuited, you can try to temporarily replace the test machine with a ground wire, such as e6** disappears after the power supply is cut off and re-energized, indicating that the signal line is damaged.
2. The inverter can try to replace the inverter module, inverter motherboard, and outdoor fan motor of the outdoor unit.
3. After eliminating the fault of indoor and outdoor communication lines, you can try to replace the fan motor of the indoor unit, if the fault still exists, you need to replace the main control circuit board of the indoor unit.

Gredo online fault**Daquan e7 is indicated: phase sequence protection or overcurrent; External feedback failures. Second, the treatment method:
1. Check whether the power access mode of the internal and external units is consistent, and the fire and neutral lines must be connected to the corresponding positions. In addition, check whether the signals of the internal and external units correspond to each other one by one, and cannot be misaligned and connected. 2. Check the voltage, if the phase sequence is reversed, you can change the phase sequence of the external power line, and do not change the residual wiring of the air conditioner itself.
3. After confirming that the voltage, phase sequence, and wiring are correct, the feedback line can be temporarily put at the indoor terminal (the double temperature machine is line 4; If the air conditioner can be turned on normally after shorting, the cause of the fault is on the outer board or the connecting line of the inner and outer unit, at this time, you should check whether the connecting line is wrong or loose, and consider replacing the external electric control board after excluding the line. 4. If the fault is still reported after shorting the feedback line and the neutral line, it may be that there is a problem with the indoor control board or operation board.

Anonymous users2024-02-03Summary. 1. Gree air conditioner shows E6, it may be a communication failure, when the black connection line between the indoor unit and the outdoor unit is loose, there may be a communication failure. 2. The Gree air conditioner shows E6, it may be that there is something dirty in the internal unit, such as dust or dirt, too much dust will affect the size of the air outlet, resulting in a decrease in the refrigeration function of the Gree air conditioner.
3. The Gree air conditioner displays E6, it may be that the fan motor of the outdoor unit of the air conditioner is not powered, and when the outdoor unit of the air conditioner is damaged, there may be no power supply, and E6 will be displayed. 4. Gree air conditioner shows E6, it may be that the compressor of the outdoor unit is overloaded, that is, the compressor is used for too long or improperly, it will produce overload phenomenon, and the compressor will stop for protection.
1. Gree air conditioner shows E6, which may be a communication failure, when the black repentant connection line between the indoor unit and the outdoor unit is loose, there may be a communication failure next to Zhou Xiang. 2. The Gree air conditioner shows E6, it may be that there is something dirty in the internal unit, such as dust or dirt, too much dust will affect the size of the air outlet, resulting in a decrease in the refrigeration function of the Gree air conditioner. 3. The Rubber Gree air conditioner shows E6, it may be that the fan motor of the outdoor unit of the air conditioner is not powered, and when the outdoor unit of the air conditioner is damaged, there may be no power supply, and E6 will be displayed.
4. Gree air conditioner shows E6, it may be that the compressor of the outdoor unit is overloaded, that is, the compressor is used for too long or improperly, it will produce overload phenomenon, and the compressor will stop for protection.
1. First of all, you can replace the signal connection line between the indoor unit and the outdoor grinding machine, which is the reason why E6 can occur, if the E6 is still displayed after replacement, you need to measure the power supply voltage of the signal port of the outer board, if there is a voltage of about 5V, it means that the voltage is not boring. 2. In the case that there is no problem with the voltage, it may be that there is a problem with the frequency conversion motherboard or module, you can measure the signal port of an external bending machine board, if the power supply voltage is about 0V-1V, it means that the control circuit board of the indoor unit is abnormal, and the circuit board needs to be replaced. 3. If the inverter module of the outdoor unit of the air conditioner is hot, or the power supply is abnormal, it means that there is a problem with the module, and it can be restored to normal after replacing the module.
If it's convenient, it's better to find after-sales maintenance, check it, and let the dust and the like be cleaned up.
Hello, first of all, thank you for your inquiry! 1. If the quality of the tile is relatively good, the cement can be directly shoveled off; 2. Soak the dry cement with some vinegar (including acetic acid) for a period of time, and then wipe it with a rag to easily remove the Qi hole. Hardened cement contains calcium hydroxide, which is alkaline and can be slowly eroded with acid.

Anonymous users2024-02-02To solve this problem, it is necessary to clean the condenser of the air conditioner so that the air conditioner can maintain good heat dissipation. If the connection between the outdoor unit and the indoor unit fails, the E6 will also display an error, so Xu Ya will check the air conditioning circuit to find out the cause of the early failure of the air conditioner. Such a fault is difficult to deal with, and you need to contact the after-sales maintenance master to help solve it.
In addition, the refrigerant leakage will also cause the outdoor unit of the air conditioner to fail to operate normally and report an E6 failure. When the air conditioner has a serious failure, Naga will enter a state of self-protection and will protect itself by automatically shutting down. At this time, it is necessary to extract too much refrigerant from the air conditioner, and if it is too little, it is necessary to replenish the refrigerant.
Gree's air conditioner shows that the E6 is a communication failure, and the specific cause of the failure requires professional service personnel to come to the door to inspect and investigate. Please click on self-service or call Gree National Unified After-sales Service**4008365315 feedback your needs and suggestions.

DB is Gree multi online in the debugging process, this is not a fault, debugging process trial operation stage, all the internal machine wire controller display DB, wait for the debugging to complete the automatic shutdown display temperature, can be operated. >>>More
Air conditioners have nameplates, there is a current value on them, the air is mainly short-circuit protection, choose one point and five times, the error point is fine, the wire selection is also based on the current, this is complicated, because the conductivity of different wire diameters is different. >>>More
This is normal;
Because the temperature of the air outlet is not the temperature of the evaporator, the minimum of 16 degrees is the temperature of the actual evaporator, that is, the real-time temperature of the room. >>>More
