What s going on with the Midea air conditioner power supply not being energized

The main reason why the air conditioner is not energized is that the outdoor leakage protector is broken, the power socket is out of power, or the power cord is broken.

Simple way to solve the problem that the air conditioner is not energized:

Step 1: Check whether the power plug of the air conditioner is plugged in;

Step 2: Check whether the remote control of the air conditioner has a power supply;

Step 3: Generally, the indoor unit of the air conditioner has an emergency switch, in order to detect the quality of the remote control of the air conditioner, if the emergency switch can turn on the power, you should choose to replace the remote control

The power outlet is dead or the power cord is broken. (Measure the current on the 220V power supply of the transformer on the main control board, and if not, check the socket and power cord, and replace it.) The main control board fuse burned.

Take off the safety and take a look at it, and replace it if it is blackened or cracked) The main control board transformer overheating protection device is burned out. (Use the ohmic file of the multimeter to measure the strong current section of the transformer, if the meter needle or number is displayed, it proves that there is no problem with the strong current section, and the resistance value of the weak current section is generally zero) The main control board circuit is disconnected.

The air conditioner is composed of electrical components such as compressors, condensers, evaporators, capillaries, solenoid valves, thermostats, fans, and running capacitors. Under normal circumstances, when the Midea air conditioner is working, when the power is turned on, the remote control starts the remote control to give the computer board a boot signal, and the air conditioner will start to work, at this time, if the indoor temperature is higher than the set temperature, the computer board will supply power to the external unit, the compressor and fan of the external unit of the air conditioner will start to work, and the refrigerant (freon) will start to circulate, so that the internal unit will achieve the purpose of refrigeration.

There are several reasons why the air conditioner does not start when it is turned on and the power supply is turned on:

1. There is a problem with the computer control panel in the air conditioner, resulting in no power supply to the air conditioner.

2. The failure of the external unit of the air conditioner, mainly the air conditioning compressor, fan, starting capacitor, etc.

3. The working mode of the air conditioner is not selected, or the temperature of the air conditioner is set to be greater than the indoor temperature.

Midea's air conditioner doesn't power for several reasons:

One may be a power socket problem, the second may be a power cord problem, and the third may be a switching power supply failure, mainly due to a fuse disconnection, rectifier bridge or switch tube short circuit.

There are many reasons for this phenomenon, the common ones are the failure of the outdoor leakage protector of the air conditioner, the failure of the socket, the failure of the compressor or the broken power cord. When encountering this phenomenon, the first thing we need to do is to check the power supply and see if the power supply is normal.

If the power supply of the Midea air conditioner is not energized, it may be that the circuit inside is in poor contact, you can ask the after-sales service of the air conditioner to solve the problem, of course, if the air conditioner has been used for a long time, then it is recommended to replace the air conditioner directly.

Double-check if the power supply is faulty, or if there is no power at the source?

First of all, check whether the socket and plug of the power supply are in good contact, and whether there is any loose place in the socket cord?

Check the indoor unit, is there any loose plug-in on the computer board?

Check if the safety of the VTH computer board is loose? Is the driving voltage of the indoor computer board normal?

Is it normal to measure the size of the room temperature sensor value? If the value is not accurate, it will be difficult for the indoor unit to work properly.

Finally, check whether the compressor of the outdoor unit is running normally, or whether the outdoor fan is normal?

The air conditioner will have a "dripping" sound when plugged in, and the wind deflector will swing a stroke. When the remote control is turned on invalid and does not respond, you can try to use the emergency switch. If there is no response, then you should start from the power supply of the indoor unit, look at the varistor and fuse and transformer.

If the emergency switch can be activated, check the temperature sensor first.

When the air conditioner is plugged in and there is no response, the first thing to ensure is that the socket at home is good. I don't know if the air conditioner plug is the kind with insurance, if it is possible that the leakage plug is broken, if it is not with it, there is a problem with the power supply in the machine, and finally check the motherboard. The remote control is broken, the design of the Gree air conditioner is that the power light is turned off after the power is turned on, you can open the cover of the air conditioner and press the emergency switch of the internal machine, if the air conditioner is started, the remote control is damaged.

The question is that the cabinet unit does not respond directly after powering on.

It is that the cabinet unit does not respond directly after powering on.

Normally, the air conditioner does not respond when it rings after it is powered on, it is likely that the battery of the air conditioner remote control is not charged or damaged, so you can carefully check the air conditioner remote control first.

2. Voltage problem.

The air conditioner does not respond instantaneously after powering on, it may also be a problem with the voltage at home, and all kinds of large household appliances are frequently used in summer, which is likely to cause the voltage overload operation and unstable situation at home, which in turn affects the normal use of the air conditioner. At this time, you can ask a professional air conditioner master to check the voltage problem.

3. The refrigerant is used up.

In the case that the air conditioner does not respond after powering on, in addition to checking whether the circuit can be short-circuited, it is also necessary to check whether the air conditioner refrigerant is used up. If it is determined that the air conditioner cannot operate due to lack of refrigerant, then you need to buy refrigerant and add it yourself.

The question is not responsive, there is no dripping sound.

It is the sound of no reaction and no dropping.

The power supply is also fine, and the voltage is normal.

The power supply is also fine, and the voltage is normal.
