Which one will tell me about the maintenance method of Midea s air conditioner not turning on

Midea's air conditioner does not turn on, Midea does not turn on, and the air conditioner does not respond mainly because of the following reasons:

1. The screen appears garbled or frozen. Press the reset button to disarm, or the battery is low.

2. The temperature is not displayed. In air supply or automatic mode, the temperature is not displayed.

3. If the receiving head is broken or cannot work normally due to moisture, check the transmission of the remote control signal. Aim your digital camera (mobile phone is also acceptable) at the transmitter and press any button to see if there is an infrared signal emitted.

4. The mode is incorrect, or the temperature setting does not meet the boot conditions. When cooling, the set temperature should be less than the indoor temperature, and when heating, the set temperature should be greater than the indoor temperature.

5. Low battery power will cause the remote control distance to be short or unable to be remotely controlled. It is recommended to remove the battery when the air conditioner is not in use, and reinstall or replace it when in use.

6. The power supply is not connected or out of power, the power conductor socket is not in good contact, or the power conductor wire diameter is thin or aging.

7. The power supply voltage is low. The starting voltage of the fixed-frequency air conditioner: 187V, the voltage fluctuation range V, the starting voltage of the inverter air conditioner: 156V, the voltage fluctuation range V, it is recommended to install a voltage regulator at home.

8. Delay protection. In order to protect the life of the press, a protection circuit is designed in the control circuit of the air conditioner computer board, and the press is started after a delay of 3 minutes.

9. Prevent heating and cold air. When the air conditioner is heating, when the temperature of the indoor unit coil is lower than a certain value, the internal unit does not run, and generally after 3-5 minutes of preheating, the internal unit starts to work.

10. The computer program of the air conditioner is chaotic, which makes the machine unable to work immediately.

11. Function lock protection. Some brands or models have a child lock function, if you are in lock mode and cannot perform any operation, you can refer to the manual to cancel.

If the air conditioner still does not turn on after solving the above problems, your air conditioner may have a functional failure, so you have to find a master.

Hope it can help you, thank you.

We all know that air conditioning plays a very important role in our daily lives. However, sometimes there may be some failures when our air conditioner is running, what is the reason why the air conditioner does not start? What are the maintenance methods? Let's take a look.

What is the reason why the air conditioner is not starting.

One: The general situation is caused by long-term operation under the shortage of Freon. System leakage is the root cause of refrigerant deficiency due to improper installation.

Solution: Replenish the air conditioner with freon.

2: The air in the system is not discharged clean during installation, and there is ice blockage from time to time, and the load of the compressor increases. The compressor temperature increases due to the increase of the compressor load, and the refrigeration oil will deteriorate for a long time at high temperature, which can not play the role of lubrication and cooling, which promotes the further increase of the compressor temperature, and the coil is reduced due to high temperature insulation, resulting in compressor damage.

Solution: Strictly control the quality at the time of installation.

Three: the power supply is not connected or out of power, the power conductor socket is not in good contact, or the power conductor wire diameter is thin or aging, and the power supply voltage is low. Fixed frequency air conditioner starting voltage:

187V, voltage fluctuation range: 198-242V, inverter air conditioner starting power 156V, voltage fluctuation range: 176-264V, it is recommended to install a voltage regulator at home because the connecting pipe is bent flat during installation, and the compressor workload increases.

Solution: Check whether the power supply cable is aged.

Four: Function lock protection. Some brands or models have the function of child lock, if you are in lock mode, you can not carry out any operation, you can refer to the manual to cancel, the compressor works at high temperature for a long time, resulting in the reduction of insulation, the coil resistance is too low, the starting current increases, and the compressor temperature rises instantaneously.

Solution: Follow the instructions to unlock.

Five: electrical line failure.

Solution: Check and repair, the differential pressure relay is disconnected, the high-voltage interrupter is disconnected, press the differential pressure relay reset button down and wait for the pressure change to close the contact or readjust the disconnection pressure.

The air conditioner does not start maintenance.

1.Caused by long-term operation under the shortage of Freon; 2.The air in the system is not discharged and there is ice blockage, and the load of the compressor increases.

The increased load of the compressor causes the compressor temperature to increase, resulting in compressor damage. 3.The power supply is not connected well or there is no power, the power lead socket is not in good contact, the power lead wire diameter is thin or aging, and the power supply voltage is low.

4.Function-lock protection is turned on.

Dear, I hope it helps you.

Questions. What to do.

1.If the air conditioner has a "beep" sound, it means that the air conditioner is basically normal, if there is no sound, it is necessary to check whether the power supply line is normal, if it is normal, it may be a remote control failure. 2.

Check whether the battery of the remote control is charged, or whether the positive and negative poles of the battery are reversed, if it is all right, it may be that the remote control is faulty. 3.In order to further confirm whether the remote control is faulty, you can open the panel of the indoor unit of the air conditioner when the power indicator is on, and see that there is a small black hole in the lower right of the air conditioner, which is the emergency switch of the air conditioner, put your finger in to turn on the emergency switch to see if the air conditioner is running normally, if it can operate normally, it means that it is a problem with the remote control.

4.If all of the above are ruled out, it is the failure of the air conditioner host, and you need to find a maintenance worker to disassemble the machine for testing. 5

Dear, follow the steps, I hope it will help you.

1. Compressor failure: The air conditioner that has been used for a long time has different degrees of compressor aging, so it is found that it cannot be turned on; 2. Refrigerant defect: once the compressor of the air conditioner lacks fluoride, it will cause the air conditioner compressor to fail to start; 3. Frost on some pipes

At this time, it is often because when the master installs the air conditioner, the original air inside is not discharged and unclean, and over time there is ice in this position.

The reason why the air conditioner cannot be turned on is often because there is a problem with the compressor of the air conditioner. In particular, the air conditioner that has been used for a long time has different degrees of compressor aging, so it is found that it cannot be turned on.

It may be that the remote control of the air conditioner cannot transmit the signal normally, and you need to check whether the remote control signal is transmitted. Use a digital camera or mobile phone camera to point at the transmitter port of the remote control, press any button of the remote control, and then see if the camera or mobile phone camera has a red light, which means that the air conditioner can transmit signals normally, and if not, it means that the remote control is broken.

What is the situation if you can't turn on the phone, if you can't turn it on, if you can't turn it on? What's going on? Normally, no, it's out of power.

1) Fluorine leakage at the connecting pipe joint;

2) The wiring is incorrect;

3), fuse burning;

4) The compressor is faulty;

5) The external environment temperature is high, and the indoor personnel are more than the United States, and the air conditioner is working at full load.

6) The power supply voltage is too low, which causes the Midea air conditioner to be difficult to start, and then stops after starting or blows the fuse of Qiaotong, so it is recommended that the user install a power regulator.

7) The air outlet of the air outlet is not large if the temperature cannot be lowered in the strong cold block room, which is the air call tank filter has too much dust, and the filter screen is cleaned.

8) Improper adjustment of the thermostat. Silence the shouting.
