Midea s vertical air conditioner cannot be started after being powered on

There are many reasons why the air conditioner can't be turned on: the first remote control reason: 1. The screen is 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.

The second reason for the power supply: 1. The power supply is not connected well or there is no power, the power conductor socket is not in good contact, or the power conductor wire diameter is thin or aging. 2. The power supply voltage is low.

Starting voltage of fixed-frequency air conditioner: 187V, voltage fluctuation range: 198-242V, starting voltage of inverter air conditioner:

156V, voltage fluctuation range: 176-264V, it is recommended to install a voltage regulator at home. The third point of protection function:

1. 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. 2. 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. 3. The computer program of the air conditioner is chaotic, which makes the machine unable to work immediately. 4. 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 above problems are still not turned on, your air conditioner may have a functional failure, please call Midea's after-sales service**4008899315 and let it arrange a special person to repair!

If you still have questions, you are welcome to ask questions to the company in the United States; I wish you a smooth work and a happy life!

If you are in trouble, say the color of the three flashing lights If you can, bring your machine model, KF-120LW behind Is it three-phase electricity? Is the phase order correct? Are there any glitches** displayed?

1. The reason why Midea's air conditioner does not respond when turned on.

1. If there is anti-cold air protection when you first turn on the air conditioner, there will be no wind coming in at this time, and you need to wait for a few minutes before there is a hot air blowing out.

2. If the air conditioner screen is garbled or frozen. Then as long as you press the reset button to release, it may also be that the battery is insufficient, and the remote control of the air conditioner cannot control the air conditioner to turn on, so you can replace the battery.

3. If the remote control display does not display the temperature. It should be that the air conditioner is in air supply or automatic mode, and the temperature will not be displayed at this time.

4. If the receiving head of the air conditioner is broken or damp, the air conditioner cannot accept the signal of the remote control, and check the transmission of the remote control signal. You can use a digital camera (mobile phone can also be used) to point at the transmitter and press any button to see if there is a red light in the mobile phone camera.

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

Second, the reason for the power supply.

1. The power supply is not connected well or there is no power, the power conductor socket is not in good contact or the power conductor is aging.

2. The power supply voltage is low, which may be because the use of the air conditioner is the peak period of electricity consumption, and it is recommended to use a voltage regulator to increase the use voltage of the air conditioner.

3. Air conditioning protection function.

1. Delay protection. In order to protect the life of the compressor, the control circuit of the air conditioner computer board is designed with a protection circuit, and the compressor will be delayed for 3 minutes before starting.

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

3. The computer program of the air conditioner is chaotic, resulting in the air conditioner cannot work normally.

4. Function lock protection. Some brands or models have a child lock function, if it is in lock mode, then no operation can be performed, and it can only be removed according to the instructions written. If the above problems still do not turn on the air conditioner, your air conditioner may have a functional failure and should be repaired.

Midea's air conditioner does not respond when turned on, which may be a problem with the remote control power supply.

1. If the air conditioner has just been turned on for a short time, it may be because of the protection of the air conditioner itself, not as soon as the air is turned on, the wind will come out, and you need to wait for a few minutes.

2. It may also be a problem with the remote control of the air conditioner, the remote control power is insufficient, and the air conditioner cannot really be turned on. Naturally, there is no response, and at this time we only need to change the battery.

3. The receiver of the air conditioner is broken and cannot receive the remote control information, so we can check the transmission of the remote control signal. You can use a digital camera (mobile phone is also available) to aim at the transmitter and press any button to see if the mobile phone camera has a red light.

4. There is a problem with the power supply. The power supply is aging or poorly contacted.

5. The mode is wrong or does not meet the boot conditions. The refrigeration setting temperature is lower than the indoor temperature, and the heating setting temperature is higher than the indoor temperature.

6. The computer program of the air conditioner is chaotic, resulting in the air conditioner cannot work normally.

7. Function lock protection, some air conditioners have child lock function, when the lock function is turned on, the air conditioner can not run, this situation can be lifted according to the instructions written. If none of the above problems are true, it may be that the air conditioner is faulty and needs to be repaired.

If the internal unit is not working, it should be the power supply, remote control, infrared receiver, something is wrong.

Dial the plug from the new plug once, plug in to see if the air conditioner has a beep sound, and then press the emergency switch on the right side of the internal machine to see if it can be started, if it can be started, use the mobile phone to shine on the remote control, and then press the switch button to see if there is any signal transmission, if there is a broken infrared receiving head, there is no remote control is broken.

The possible causes are as follows: the fuse of the air conditioner is back blown when the power supply voltage is unstable; transformer damage; There is poor contact in the circuit in the air conditioner; The supply voltage is too low. 1. Similar to the Midea of this large household appliances in daily use, due to the overpower of the load is too high, so the fuse is easy to blow out, if the fuse is blown out, it is easy to have the problem of not being energized, in this case, we need to replace the fuse, so that our air conditioner can be used normally.

2. In our daily life, when the transformer of the air conditioner is not damaged, there may also be a situation where the air conditioner is turned on but there is no way to power on, in this case, we need to replace the transformer to solve this problem. 3. When the circuit of the air conditioner is not in good contact or the socket of the socket is relatively loose, we may encounter the situation that the machine is turned on but cannot be powered. 4. Similar to Midea, this fixed-frequency air conditioner has a certain voltage range, but when the voltage passing through the circuit is lower than the rated voltage, it may produce a situation where the air conditioner is officially turned on but not powered on, in this case, we need to consult professional maintenance personnel to repair this kind of problem, so as to better solve this kind of problem.

Summary. 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.

Midea's air conditioner doesn't respond when it's powered on, what's wrong if it doesn't start.

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

If the emergency switch can not be activated, then 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 panic switch is in**.

The emergency switch needs to open the lid inside the air conditioner, and there should be an obvious button inside.

Is it in that little round hole that I marked?

That's right. Well, I've encountered the chain before and only experienced this situation, which is generally a button for the probability of the inner machine in the empty shed. It's all in a small hole, it's not a protruding button, and it needs to be guided in with a stick to open it.

It's useless. If it doesn't work, it could be something else.

I'm also here to help you find a beautiful service**.

You can go and ask about their after-sales service. Good.

If Midea's air conditioner doesn't turn on, it may be a problem with the remote control of the air conditioner. The remote control of the air conditioner cannot transmit a normal signal. Check if the remote control is damaged or dead.

If it's not a problem with the remote control, it's possible that there is a problem with the air conditioner compressor. If the air conditioner is used for a long time, the compressor will age, resulting in the inability to turn on.

Midea air conditioner failure causes and solutions:

1.Try turning the computer on and off first, check if it is a problem with the remote control, and see if the battery of the remote control is charged.

2.There may be a problem with the board. Inspect outlets, circuit boards, fans, and compressors.

3.The compressor shaft or motor windings are burned out. You can look for such a plug from the desktop version, and then look for the sensors line by line.

4.The starter relay or starter capacitor is damaged. It means that the indoor unit of the air conditioner is too dirty. Turn off the mains power, open the lower cover, and take out the filter for cleaning.

5.The thermostat fails, the contacts cannot be closed, and the compressor circuit cannot be switched on, resulting in the compressor not starting.

The fuse in the special circuit of the air conditioner is blown out, or the contact of the power switch is poor; The power supply used by the air conditioner is too low, and when the voltage is lower than 10 of the single-phase normal voltage (220V), that is, 198V or below, it is difficult for the refrigeration compressor in the air conditioner to start; The knob on the temperature controller is not in place; High pressure relay action, such as the condensing pressure is too high, so that the high pressure relay action stops the operation of the compressor.

If Midea's air conditioner won't start, there may be several reasons:

1.Power supply problem: Check whether the air conditioner is plugged in and whether the power supply is normal.

2.Remote control problem: Check whether the remote control has power and whether it is operated correctly.

3.Indoor unit failure: Check whether the slip pure indoor unit is faulty, such as whether there is an alarm** display.

4.Outdoor unit failure: Check whether the outdoor unit is faulty, such as whether there is an alarm** display.

5.Line fault: Check whether the air conditioning circuit is normal, such as whether there are loose, short circuit and other problems.

If none of the above methods can solve the problem of delay, it is recommended to contact a professional air conditioner maintenance personnel for inspection and maintenance.
