Midea s air conditioner boot display and timing display, can t start, what s going on

The remote control cancels the timer.

Hello! Faulty air conditioner? I'll tell you how to solve these failures, which should save you a lot of detours.

When encountering a failure of the air conditioner, we must strictly follow the scientific procedures, and do not act blindly and disassemble at will when the situation is unclear, the fault is unclear, and there are countless in the heart. The consequence of this often amplifies existing faults, increases operating costs, shortens the normal service life of equipment, and leads to early scrapping of equipment.

The press does not start, there is no problem with the temperature setting, but there is no response when the power is on? If the press does not turn the fan, you must look at the capacitor first.

The capacitor bulge needs to be replaced, and the capacitor is checked for power supply.

If there is a power supply, the overload protection of the press checker is the key.

If there is no power supply in the house, first check the connecting wires.

Secondly, it is best to look at the temperature control and replace the temperature control.

The relay is a key point, and the front drive should be judged.

If all of the above are normal, the following things will be easy to do.

Motherboard repair or replacement is subject to the user's decision.

The air conditioner is not refrigerated well or not refrigerated].

This problem is most common, and the lack of fluorine in air conditioners is the key.

When the machine is turned on, first touch the trachea and judge it by the temperature.

If it is cold, the speed of the fan may be low.

The inner tube scales and dust are cleaned or replaced.

If the inner tube is not considered cool, the thick tube may be flattened.

The return air temperature is not cool, and then touch the intake air to judge.

The air intake is cold and frosty, and fluoride is added to try again.

If the frost slowly disperses, it is a good decision to lack fluoride.

It is not difficult to see the aging of the press, and the lack of exhaust is the key.

Four-way gas is also commonly judged by fluoride collection.

High-pressure scales must be seen to be dirty, and they will be slow to refrigerate.

- Finally, I wish the work to go well, fix the air conditioner earlier, live a happy life——— please give an answer if you think it is good, give a good review, and wish you a better life———

There are many problems with beauty, and my family is also beautiful, and the garbage is going to die.

Just cancel the timer.

If the power supply is normal and the remote control cannot be turned on, you can turn on the manual switch on the air conditioning panel by hand, if it can be turned on, it means that the remote control or receiving board is faulty, and you can find the manufacturer to replace the accessories.

If it can't be opened with a manual switch, it means that the main control board of the air conditioner is faulty, and the main check is whether the fuse is burned out? Is the transformer good? Is the rectifier power supply good?

Midea's air conditioner doesn't turn on, Midea doesn't turn it on, and the air conditioner doesn't respond. The reasons are mainly divided into three points: 1. Reason, 2. Power supply reason, 3. Protection function.

The above questions will be explained in detail for you. The first 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. Use a digital camera (mobile phone is also available) to aim at the transmitter and press any button to see if there is an infrared signal. 4. If the mode is not correct, or the temperature setting does not meet the start-up 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 on the first grinding. 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 still do not turn on the air conditioner, your air conditioner may have a functional failure and should be repaired.

The total flashing of Midea's air conditioner timing light may be the cause of room temperature sensor failure, indoor coil sensor failure, outdoor line residual coil sensor failure, outdoor phase failure or phase sequence protection failure. 1.Check the cause of the fuse blowing inside and outside the air conditioner, and take measures to prevent it from blowing again.

It should be adjusted and repaired in time. It is recommended that households with air conditioners be equipped with a dedicated power supply, which can basically prevent this kind of failure. 2.

If the local supply voltage is constantly low, it is necessary to stabilize it with a reliable power supply. At the same time, it is recommended that households with more household appliances use a dedicated power supply. 3.

Adjust the dial button on the thermostat to the desired position, i.e. according to the desired temperature in the air-conditioned room. 4.Check the cause of the high condensation pressure and eliminate it so that the condensation pressure returns to normal pressure.

5.Check the causes of refrigerant insufficiency in the refrigeration system and rule out these causes so that the suction pressure can be restored to normal pressure. 6.

Check the original acacia panicle cause of overload of compressor motor and fan motor and eliminate it; Press the reset button of the protection relay. 7.Check if the timer on the remote is pressed, just power off, restart and turn off the timer.

If none of the above is true, it is recommended to contact Midea's after-sales service for processing.

Midea air conditioningThere are several main reasons why the timer light flashes without response:

1. The fuse in the special circuit of the air conditioner.

It is blown out, or the contact of the power switch is poor, or the power supply is out of phase. At present, many users use a power supply in combination, and the power supply is abnormal due to the abnormal operation of other electrical appliances.

2. The power supply used by the air conditioner is too low, when the voltage is less than 10% of the single-phase normal voltage (220V), that is, 198V or below, it is difficult to start the refrigeration compressor in the air conditioner.

3. The knob on the temperature controller is not dialed to the appropriate position, such as dialing to a higher position, when connected to the power supply, the temperature in the air-conditioned room has not reached the upper limit of the set temperature (the temperature at the starting point), and the compressor cannot start running.

4. The action of the high-pressure relay, such as the condensation pressure is too high, so that the high-pressure relay acts, and the operation of the compressor is stopped.

5. Low-pressure relay action, such as refrigerant in refrigeration system.

Insufficient, resulting in the compressor suction pressure is too low, so that the low-pressure relay acts, stopping the operation of the compressor.

6. When the current of the compressor and fan motor is too large, the overload protection relay will act and cut off the power supply.

How to maintain the air conditioner of the United States:

1. Remove the debris from the vent to ensure normal ventilation. Observe whether the outdoor rack is loose, and clean the outdoor ventilation grille for foreign objects. At the same time, keep the vents unobstructed.

2. Clean the surface of indoor and outdoor heat exchangers to improve the efficiency of heat exchangers. When cleaning the indoor heat exchanger, you should carefully remove the rental cherry panel, scrub it with a soft rag, and use a small brush to gently scrub the heat exchanger of the inner machine, so as to achieve the purpose of removing dust and harmful accumulation that can multiply germs.

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.

Common faults of air conditioners and their causes:

1. The air conditioner is leaking.

Reason 1: The air supply system is blocked.

Mainly because the filter screen is blocked, a low air stall is used when it is wet, if the air volume is small, the evaporation temperature of the internal machine is reduced, the evaporator is frosted or even frozen, and the water leakage is caused by a long time.

Reason 2: Clogged drainage system.

After the air conditioner is used for a long time, there will be water leakage caused by the water guide groove and the drain pipe being blocked by debris, and the water guide groove will be leaked due to cracks, poor connection pipe joints, and flattened drainage pipes during installation.

2. The new air conditioner is not refrigerated.

Reason 1: The voltage of the power supply is insufficient.

The air conditioner is most afraid of voltage instability, and it will lead to failure if the fuse is blown in an instant, especially during the peak of electricity consumption. The performance is: when the voltage is normal, the air conditioning and refrigeration are also normal; When the voltage is unstable, the air conditioner refrigeration is intermittent.

Reason 2: The outside temperature is too high.

In order to have a clean appearance, some real estate projects install outdoor units in a hidden small space or even put multiple outdoor units in a small space, which can easily cause air circulation in the space where the outdoor unit is located, resulting in the radiator being unable to dissipate heat normally.

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.

There are about five reasons for this situation, one is because the air conditioner turns on the automatic mode and stops when it reaches the set temperature, so there is a timed fault illusion when it is not turned on. Second, because the voltage is unstable, the machine has compressor overcurrent protection. Third, because the indoor temperature is too high, there is a protective shutdown of the air conditioner, so there is no need to worry.

Fourth, the indoor fan does not blow the fault, and the protection of the machine is shut down. The last reason is that the compressor protection device is tripped, which is also a kind of protection program for the air conditioner.

Solution to this situation:

The automatic mode when the air conditioner is turned on, and it stops when it reaches the set temperature, which may be an illusion of failure, we can turn off the power and restart it after a while to try again.

If the voltage is unstable, if it is not normal, we need to turn off the air conditioner and power supply, and replace it with a new voltage regulator.

If the temperature of the indoor coil is too high, it is easy to make the air conditioner heat abnormally, and then it will turn on the protection mechanism and turn off the machine, at this time, we still do not use the air conditioner, and wait for the environment to stabilize before turning on.

If the air conditioner fan fails and does not blow the air, it will also stop for protection, it may be that the external unit is malfunctioning, or it may be frost or other obstacles, just clean it.

Finally, there is a problem with the receiver board of the air conditioner, and the receiver head needs to be replaced, which needs to be dealt with by professional maintenance personnel.

Why does the Midea air conditioner suddenly start up? Hello, dear, one, the reason why the Midea air conditioner does not respond when it is turned on 1, if you just turn on the air conditioner when you have a cold wind protection, there will be no wind coming in at this time, and you need to wait for a few minutes before a hot air blows 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. 2. Reasons 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.
