What is the fault of the Midea E3 air conditioner, and what is the fault of the Midea air conditione

You can check whether the ambient temperature is too low first, and you can raise the temperature appropriately to solve the problem. 1.Whether the ambient temperature is too low, resulting in the failure of Midea's air conditioner to operate normally, resulting in a fault code E3.

If there is a problem with the main board or display panel of the indoor unit, the Midea air conditioner will also not be able to operate. The voltage abnormality causes the E3 fault code, and the connection wire and plug wiring of the external unit fail. At this time, the current cannot pass through the main air conditioner, and the air conditioner cannot work properly, which will cause the E3 air conditioner system to leak or block.

2.Check whether the internal air duct of the Midea air conditioner is stuck, open the shell of the Midea air conditioner to see if there is any foreign object blocking the air duct, that is, the E3 fault needs to be cleaned and eliminated. Check whether the fan cord connector of the Midea air conditioner is loose or damaged, so that the Midea air conditioner will show an E3 fault when in use.

If the connector is loose, reconnect it. If the line is damaged, connect the line or replace the internal fan. In this way, the fault of the Midea air conditioner will be eliminated, and it will not be displayed to check whether the capacitance of the internal fan is normal.

Abnormal capacitor operation will cause Midea's air conditioner to display E3. If the abnormal fan capacitor is replaced, the E3 display fault will not be eliminated when the Midea air conditioner runs again.

The E3 error is a high pressure abnormality. This is mainly due to the abnormally high pressure of the outdoor unit. Remedies for this differ when cooling and heating are used.

If you get an E3 error** when using the air conditioner, check the heat exchanger of the outdoor unit.

If you receive an E3 error** while using heating, it is most likely due to dirt on the internal filter of your air conditioner. Please open the lid of the air conditioner and check the filter. If dirt builds, wash it off with water or remove it with a specialist cleaner.

Precautions for daily maintenance of air conditioner

1. Adjust the temperature correctly: the temperature should be set according to the actual situation such as your own feeling of cold and heat, the number of people in the space, etc. If the temperature setting is too low, due to the large temperature difference between indoor and outdoor, and the heat dissipation is faster, the compressor will be frequently started and stopped, which shortens the service life of the air conditioner and consumes more energy.

2. Clean the air conditioner regularly: Regularly remove the filter screen of the indoor unit for cleaning, which can effectively improve the dust removal effect of the air conditioner and improve the ambient air quality. Regular cleaning of the heat sink of the outdoor unit can effectively improve its heat exchange coefficient and heat exchange efficiency, and improve the working efficiency of the air conditioner.

<> Midea E3 fault refers to the loss of control of the fan speed, which may be the outdoor fan is broken, the capacitor is broken, or the outdoor circuit board has no fan output, there are three specific situations. Clause.

1. The indoor fan does not rotate, very slowly, or very quickly. Clause.

2. The fan motor has no feedback signal output and needs to be replaced. Clause.

3. The computer board of the indoor unit has a fault in the detection circuit and needs to be replaced with the computer board.

How to solve this fault of Midea air conditioner display e3.

1. Determine whether the ambient temperature is too low.

2. Short connect the LPP plug on the main control board and the neutral line N on the motherboard, if the indoor unit is running normally, you can determine that the main board or display board of the indoor unit is fine, and the fault appears on the indoor and outdoor unit connection wires, plug joints or low-voltage switches of the outdoor unit.

3. Connect the cable and plug of the external machine, adjust the multimeter to the ohmic block, connect one meter pen to the LPP protection wire unplugged on the motherboard, and connect the other meter pen to the zero line N, if the resistance value is 0, it means that the fault is on the low-voltage switch, otherwise it is a line problem.

4. Use the pressure gauge to determine whether the system is leaking fluorine or blocked.

<> Midea air conditioner E3 refers to the speed of the fan in the room being out of control. Specifically, there are three situations: 1. The indoor fan does not rotate, very slow, or very fast.

2. The fan motor has no feedback signal output, and the motor needs to be replaced. 3. The detection circuit of the indoor computer board fan is faulty, and the computer board needs to be replaced.

Troubleshoot E3 Method:

1. Check whether the assembly of the wind turbine is loose or stuck, and adjust it if so.

2. Check whether the wiring of the indoor electronically controlled fan is reliable, and adjust it if there is a problem.

3. If the fan cannot be used to detect the AC voltage between the red line and the black line of the strong current output port of the fan

a. If there is no AC voltage output, it is a motherboard fault.

b. If there is AC and voltage output fluctuating wind wheel along the rotation direction of the wind wheel by hand, if the fan can be started normally, it is a motherboard failure, otherwise, it is a motor failure.

Compressor low pressure protection.

Midea air conditioner E3 is the protection in the event of overvoltage or undervoltage failure**, which can be solved according to the specific fault.

Check whether there is a lack of refrigerant inside the air conditioner, and if it is missing, it should be increased appropriately.

Use a multimeter to detect the circuit board and low-voltage switch, the resistance value is 0 on behalf of the low-voltage switch failure, which can be repaired or replaced, and the resistance value is not 0 on behalf of the line failure, and the circuit board of the core should be updated.

Midea Air Conditioner Shows E3 Reasons:

Midea's air conditioner is turned on for one minute and shows the fault of the e3, which means over-voltage and under-voltage protection, check whether the AC voltage is too high or too low, and repair it according to the actual situation.

In fact, when we use it in our daily life, not all of them are household air conditioners, and there are ** air conditioners, and some cabinet models will still fail** E3 means that the temperature sensor T3 is abnormal, to check whether the resistance value of the thermistor sensor T3 itself is normal, and whether the sensor connection line is open, open or poorly contacted.

Midea's air conditioner display E3 fault refers to the failure of the outdoor ambient temperature sensor. The reason for the failure of this location may be that the outdoor circuit board has no fan output, or it may be due to the outdoor fan stopping working, or the fan speed is out of control, etc., which needs to be applied for on-site maintenance. The specific brief introduction is as follows:

1. It may be caused by the failure of the outdoor circuit board without fan output, the outdoor fan is broken, the capacitor is broken, or the fan speed is out of control.

2. You can check whether the wind turbine will be stuck, and then turn on the machine to the air supply to see if the fan is rotating, whether it is not rotating, or whether the fan is rotating at an unadjustable wind speed.

3. You can also short connect the LPP plug on the main control board and the neutral line N on the motherboard, if the indoor unit is running normally, you can determine that the main board of the indoor unit is okay with the code blocking or display board, and the fault appears on the indoor and outdoor unit connection wires, plug joints or low-voltage switches of the outdoor unit.
