What is the fault of Midea air conditioner E6, and what is the cause of Midea air conditioner fault

Midea's air conditioner display**E6 means: the indoor evaporator temperature sensor is open or short. Midea air conditioner shows the meaning of the fault **:

1. E1: Error reading EEPROM parameters during power-on 2, E2: Error in zero-crossing detection 3, E3:

Fan speed runaway 4, E4: Quadruple current protection 5, E5: Indoor room temperature sensor open or short circuit 6, E6:

The room evaporator temperature sensor is on.

The air conditioner shows that the E6 is faulty** means different things on different models:

1. The fault 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 should be detected;

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.

When encountering a failure of the air conditioner, we must strictly follow the scientific procedures, and do not act blindly and disassemble at will when the situation is unclear and the fault is not clear. The consequence of this often amplifies existing faults, increases operating costs, shortens the normal service life of equipment, and leads to early scrapping of equipment.

It may be a compressor failure, call its after-sales service**, and find a professional maintenance master to check the reason.

Procedure Method.

1 There are several reasons for this:

2 1. The phase sequence of the circuit and power supply in the air conditioner is wrong, and the air conditioner will display E6 fault**.

3 2. If there is a problem with the outdoor unit of the air conditioner, the air conditioner will display an E6 fault**.

4 3. If there is a problem with the connection between the internal hang-up of the air conditioner and the external cabinet line, the air conditioner will display the fault of E6**.

5 4. If there is a problem with the indoor temperature sensor of the air conditioner, the air conditioner will show the fault of E6**.

6 5. The air conditioner should be used frequently, if it has not been used, the air conditioner will show the fault of E6**.

Nowadays, every household is equipped with air conditioning, which can make us feel warm in winter and cool in summer, which greatly reduces the incidence of colds and other diseases. And due to some of our irregular mold combustion operations, air conditioning failures occur from time to time. Failure of E6 etc. due to some external reasons.

Don't panic when the fault occurs, just call the after-sales maintenance service personnel to help us solve the problem. What is e6? E6 is that after the air conditioner is damaged by a fault, the air conditioner can automatically summarize its fault, so as to form the fault we see **E6 alarm.

To put it simply, the appearance of E6 means that the outdoor unit of the air conditioner is faulty and the air conditioner cannot work normally.

E6 as an air conditioner failure** usually contains the following seven major problems. 1. Communication failure; 2. Contradictory models; 3. Overlapping internal machines; Fourth, the power supply of the external unit problem; 5. Necrosis of air conditioner; 6. Disconnection or leakage of internal and external machines; 7. The indoor circuit board is broken.

How can we solve these seven problems? First of all, when the problem arises, you need to go indoors to check whether the external communication signal line is broken or short-circuited. If the e6** does not disappear after the power supply is disconnected and restarted, the signal line is damaged.

The second step is to check the line. If it is found that the line is disconnected or in poor contact with the wire end, the failure of the air conditioner itself does not need to be considered. The third step is to make full use of the fixed frequency machine.

First eliminate the fault of the indoor and outdoor communication lines, and then determine whether it is the fault of the indoor unit fan motor. If the fault still occurs, it is necessary to replace the main control circuit board of the indoor unit.

The biggest failure factor of the outdoor unit failure is the poor heat dissipation effect of the condenser inside, and the heat dissipation effect of the outdoor unit deteriorates, so that the air conditioner produces overheating protection. The fault E6 of the outdoor unit of the air conditioner is not running, and we need to clean the condenser of the air conditioner to maintain a good heat dissipation effect for such factors. These are not the only reasons, but also the leakage of refrigerant and the breakage of components.

Therefore, in daily life, it is very important to maintain and repair the air conditioner regularly in order to effectively delay the service life of the air conditioner.

Communication failures. 1. The air conditioner shows E6: Failure to communicate with caution.

2. Communication troubleshooting methods:

1. Check whether the connecting line of the display board is broken or damaged, and check whether the plug joint of the display board connection line group is good and beating, if there is a problem, replace or adjust it accordingly;

2. Check whether there are obvious welding quality problems in the welding of the circuit components at the bottom of the electronic control motherboard or display board, and replace them accordingly if they exist;

3. Use a cabinet indoor display board that can work normally to replace the original faulty cabinet indoor display board, if the air conditioner is still faulty, it is judged that the main board of the air conditioner is faulty; If the air conditioner failure disappears, it means that the display board of the air conditioner unit is faulty;

4. Use a cabinet indoor motherboard that can work normally to replace the original faulty cabinet indoor motherboard; If the air conditioner fault disappears, it is judged that there is a fault in the main board of the air conditioner; If the communication between the motherboard and the display board is still faulty in the air conditioner, it can be judged that the air conditioner display board is faulty.
