What is the fault of the Victor air conditioner showing 7E?

1. Frequency conversion cabinet machine.

1. E1 represents that the current in the press is too large, and the temperature sensing package is open.

2. E2 stands for the anti-freezing protection of the internal temperature tube.

3. E3 represents the inner sensor short open circuit.

4. E4 stands for evaporator tube short circuit.

5. E5 communication fails, n and l cannot be reversed.

2. Ordinary cabinet machine.

1. E1 indicates the high voltage protection of the press.

2. E2 indicates internal freeze protection.

3. E3 means low voltage protection of the press.

4. E4 means exhaust temperature protection.

5. E5 means over- and under-voltage protection and low-voltage protection.

3. Common faults**.

E1: Compressor High Pressure Protection.

1. There is an obstacle in front of the condenser.

2. Start refrigeration when the outdoor ambient temperature is higher than 43 degrees.

3. The control loop is abnormal.

4. The pressure of the high-pressure pipe is over-pressed, and the high-pressure switch is activated.

E2: Compressor low pressure protection.

1. Insufficient refrigerant.

2. The expansion valve is half-blocked, and the solenoid valve is faulty.

3. The filter is half blocked.

E3: Evaporator anti-freeze protection.

1. The indoor fan does not rotate or the tuyere is blocked.

2. The indoor environment temperature is lower than 18 degrees.

3. The plug of the air conditioner temperature sensor tube is broken.

4. The air conditioning control circuit is abnormal.

5. The plug of the temperature sensor tube is not plugged in properly.

E4: Compressor exhaust pipe temperature is too high protection.

1. Aging of compressor.

2. The system is blocked.

3. The heat dissipation of the external unit is not good.

E5: Overcurrent protection.

E7 in the air conditioner is an air conditioner fault** is an overcurrent or phase sequence protection external feedback fault.

If it is not a new machine, it can be judged to be overcurrent protection, and its overcurrent protection means that the voltage is low, and the starting capacitor of the compressor can be replaced, which can basically solve the problem, which is a common problem of old air conditioners. If it is a new air conditioner installation, it should be overhauled according to the following treatment method:

1. Check whether the power connection 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 signal connection lines of the internal and external units correspond one-to-one, and cannot be misaligned connections;

2 Check the voltage, if the phase sequence is reversed, you can change the phase sequence of the external power line.

Dear, you are very happy to answer the front point for you: Vic air conditioning failure**Daquan e01 A Vic air conditioning failure**Daquan e01. Air supply system:

The main reason is that the filter screen is blocked, the evaporation temperature of the internal machine is reduced, and the evaporator is frosted or even frozen, which leads to water leakage for a long time. Drainage system: After the air conditioner is used for a long time, the water guide groove and drainage pipe will be blocked by debris and leak.

Why does an air conditioner not refrigerate. Reason 1: The voltage of the power supply is insufficient.

Original silver let the cause two: the outside temperature is too high. Why does the air conditioner squeak.

Reason 1: The sound of the compressor belt.

Summary. Kiss is happy to answer for you: Vic air conditioner failure **h2 reasons are as follows:

1.Check whether the temperature sensor of the indoor unit is damaged or displaced. If it is damaged or displaced, the sensor needs to be replaced or reinstalled.

2.Clean the indoor unit filter and evaporator to make sure they are not clogged or dirt has accumulated. 3.

Check that all wires and connectors are properly connected and fastened. <>

Dear Kiss is happy to solve the trace for youAnswer: Vic air conditioner failure **h2 causes are as follows: 1

Check whether the temperature of the indoor unit is damaged or displaced. If it is damaged or displaced, the sensor needs to be replaced or reinstalled. 2.

Clean the indoor unit filter and evaporator to make sure they are not clogged or dirt has accumulated. 3.Check that all wires and connectors are properly connected and fastened.

<> the compressor current exceeds the rated value, the air conditioning circuit may cut off the power supply, which is an overload protection measure.

Kiss to your expansion, precautions for the use of air conditioners: 1Note the order of the opening of the door and the outside.

2.Reduce the number of times you open the door. 3.

Adjust the height of the air outlet correctly. 4.Clean the filter regularly.

5.Prevent the occurrence of shiki. 6.

Hello dear, there are many kinds of Vic air conditioner failures**, among which the more common ones include the following:1 e1：

Indicates that the indoor temperature sensor is faulty and needs to be replaced. 2. e2：

Indicates that the outdoor temperature sensor is faulty and needs to be replaced. 3. e3：

It means that the indoor fan motor is faulty and needs to be replaced. 4. e4：

The outdoor fan motor is faulty and needs to be replaced. 5. e5：

Indicates that the indoor and outdoor communication is faulty, and the indoor and outdoor communication lines need to be checked. 6. e6：

It means that the pipe temperature of the outdoor unit is too low or too high, and the cooling or heating system of the outdoor unit needs to be checked. 7. e7：

It means that the communication line of the indoor and outdoor units is faulty, and the indoor and outdoor communication lines need to be checked. 8. e8：

It means that the power supply voltage in the room is too low or too high, and the indoor power supply voltage needs to be checked. The above is only a part of the Victor air conditioner failure**, different ** represents different fault types, which need to be repaired and dealt with accordingly according to the corresponding **. Extensions:

How to repair and deal with the Vic air conditioner failure**? First of all, you need to determine the specific type of fault based on the fault** on the display. Then, according to the different types of faults, the corresponding repairs and treatments are carried out.

For example, if there is a fault**e1, the room temperature sensor needs to be replaced; In the event of a fault**E6, the cooling or heating system of the outdoor unit needs to be checked.

<> to give you the expansion, the maintenance method of the air conditioner: 1. The secret of switching, the use of air conditioner should be switched on and off frequently. Second, the temperature secret, air conditioning operation should pay attention to carefully adjust the temperature, to avoid overheating or overcooling.

Third, the secret method of the filter, the air conditioner generally needs to be cleaned and maintained once before and after use in summer and autumn. Especially the protection of the filter. <>

E01 represents the "knob fault" in the fault code of the Victor air conditioner, which is generally caused by the poor contact or contact open circuit of the central control knob, or it may be caused by the problem of the control panel of the Victor air conditioner. It can also be the result of poor or broken contact with the connector, or a connection problem between the control board and the control panel. To solve the problem of the socks, you can try to check the contact of the central control knob to see if there is any looseness, if there is looseness, you can try to use insulating glue maintenance; Secondly, check the contact of the connector, and if you find that the contact is bad or the contact is broken, you can try to rewire; Finally, check the connection between the control board and the control panel, and if you find that the connection is a macro model problem, you can try to reconnect the wire.
