Solution:1Clean the filter before the evaporator.

2.Take off the antifreeze thermometer head of the internal unit and put it in hot water, turn on the machine for trial operation, if E2 is not displayed, then there is a problem with the sensor and needs to be replaced.

3.If all of the above is normal, it means that there is a problem with the circuit board and needs to be replaced.

The meaning of the E2 failure of the Gree air conditioner: anti-freezing protection.

1.Anti-freezing protection means that when the evaporator temperature is too low, the air conditioner enters a protective state in order to protect itself.

2.In the refrigeration and dehumidification mode, the compressor starts for 6min, and when the T steamer<-5 is detected for 3min continuously, the indicator light flashes and shows the fault **E2 and the CPU will issue a command: stop the compressor and external fan, and do not shield the buttons.

3.When T steaming》6 and the compressor has been stopped for 3min, the indicator light is off, the LCD recovery display, and the original state is running.

The meaning of the E2 displayed by Gree air conditioner is that the air conditioner has entered the state of anti-freezing protection, which is that the evaporator temperature of the air conditioner is too low, and the cold air dissipation capacity of the air conditioner is insufficient, and the air conditioner filter needs to be cleaned.

A few common causes of anti-freeze protection:

1. The filter screen is dirty and blocked.

2. The surface of the evaporator is dirty and the air volume is small.

3. Lack of fluorine in the system.

4. There is a flattened place in the connecting pipe.

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

6. The indoor ambient temperature is lower than 18 degrees.

7. The temperature sensing head of the tube is broken.

What is the reason for the appearance of E2 in the air conditioner.

After running for a period of time, the compressor and outdoor fan are stopped, and the indoor fan is still running, and the fault is displayed**E2 (no display for light box type):

1) Check whether the evaporator is frosted, if it is frosted, it will show fault **e2. The causes of frosting may be:

1) If the system lacks fluorine, the pressure gauge can be used to measure the system pressure, and the operating current can be measured with a clamp meter.

2) When the temperature is low (below 25), frost may form in the evaporator during refrigeration operation.

3) The surface of the evaporator is dirty and the air volume is small.

2) If the evaporator is not frosted, it may be that the position of the indoor tube temperature head is wrong, resulting in the local temperature being too low, and the tube temperature head can be moved out and tried again.

3) The indoor tube temperature sensor package is broken or broken.

4) It could also be a malfunction of the display itself or a problem with the control board.

5) The filter is too dirty.

6) The system is dirty and blocked.

7) Indoor motor speed is too low.

Gree air conditioner display E2 means "internal unit anti-freeze protection". That is, when the evaporator temperature is too low, the air conditioner enters a protective state in order to protect itself. If there is no problem with the temperature sensing head when E2 occurs, it means that the evaporator is dirty or the air speed of the internal unit is too low.

A few common causes of antifreeze protection and solutions:

1. The filter screen is dirty and blocked, and it can be solved by cleaning the filter screen.

2. The surface of the evaporator is dirty and the air volume is small. Clean the evaporator and you'll be fine.

3. System failure. When the evaporator of the internal machine is frosted during normal operation, it means that the system is faulty. Remove the chamber tube thermob from the evaporator. If e2 does not appear after removal, it is also a system failure. Need to find after-sales maintenance.

4. Control system failure. When the internal evaporator does not frost during normal operation, and the pressure (normal) is also normal, it means that there is a problem with the tube temperature sensor in the control system and needs to be repaired after sale.

Workaround for e2 to appear:

1. Check the filter. If it is dirty, it needs to be cleaned, and if it is not, the internal evaporator needs to be cleaned.

2. Analyze whether it is a control failure or a system failure

First look at whether there is frost in the evaporator of the internal machine during normal operation, if it is frosty, it means that the system is faulty. Remove the chamber tube thermob from the evaporator, if E2 does not appear, it means that there is a system problem.

If there is no frost and the pressure (which is normal) is normal, there is a problem with the tube temperature sensor in the control system.

3. Check whether the indoor ambient temperature is too low, whether the speed of the indoor fan is too low, whether the indoor evaporator is too dirty, whether the system is blocked, and whether the inner pipe thermometer is misprotected due to open circuit.

<> Gree air conditioner E2 means that it has entered the state of anti-freezing protection. Solution: Check the filter screen first, if it is dirty, it needs to be cleaned, if Nian Nian Li is not dirty Gao Feng, then clean the evaporator of the internal machine.

Then take a look at whether there is frost in the evaporator of the internal machine during normal operation, if it is frosty, it means that it is a system failure. If there is a problem with the tube temperature sensor, the tube temperature sensor needs to be serviced.

The causes and solutions of Gree air conditioner E2 are: cleaning the air conditioner filter, adjusting the temperature of the air conditioner, checking the connection lines of indoor and outdoor units, removing the dust of the outdoor unit of the air conditioner, and checking the leakage of the air conditioner refrigerant.

1. Clean the air conditioner filter.

The air conditioner filter is a very important part of the air conditioner, which filters dust, bacteria and other pollutants in the indoor air and purifies the air. However, because the filter cannot be reused, it is easy to clog, which affects the refrigeration effect. It is recommended that users clean the air conditioner filter once a quarter to ensure the cooling effect of the air conditioner.

2. Adjust the temperature of the air conditioner.

If the temperature of the air conditioner is too low, it will not only waste energy, but also easily lead to the failure of the Gree air conditioner E2. Therefore, users should adjust the temperature of the air conditioner reasonably and adjust the temperature to a comfortable room temperature, not too low a room temperature. Normally, the temperature of the air conditioner should be between 22 -28, so as to effectively ensure the normal operation of the air conditioner.

3. Check the connection lines of indoor and outdoor machines.

The failure of the Gree air conditioner E2 may also be caused by a poor connection line. Users can check whether the connection between the indoor and outdoor units of the air conditioner is firm, loose or damaged, and replace and reconnect immediately if found. In this way, the occurrence of Gree air conditioner E2 failure can also be avoided.

4. Remove the dust from the outdoor unit of the air conditioner.

After the use of the Gree air conditioning room Chitan outdoor unit for a long time, the dust will accumulate more and more, which will affect the refrigeration effect of the air conditioner and easily lead to E2 failure. Therefore, users should clean the surface dust and dirt of the outdoor unit in time, and can use special cleaning equipment or ordinary wiping cloths to ensure the long-term normal operation of the air conditioner.

5. Check the leakage of refrigerant in the air conditioner.

The failure of the Gree air conditioner E2 may also be caused by the leakage of the air conditioner's refrigerant. Users can observe whether there is refrigerant leakage during the use of the air conditioner by listening and smelling and observing, and take timely measures to repair and replace it. Avoiding refrigerant leakage can effectively prevent the occurrence of Gree air conditioner E2 failure.

The failure of Gree air conditioner E2 usually refers to the failure of the indoor temperature sensor or the communication failure of the indoor and outdoor temperature sensor. Here's how to deal with it:

1.Check that the room temperature sensor is damaged or loose, and if so, it needs to be replaced or re-fixed.

2.Check whether the communication line of the indoor and outdoor temperature sensor is normal, if the line is damaged or poorly connected, it needs to be repaired or reconnected to hold Xiaoheng.

3.If the above two situations are ruled out, but the E2 fault still exists, you need to contact a professional air conditioner maintenance personnel for maintenance and repair.
