1. The reasons for the flashing lights of Midea's air conditioner include:

The wind speed is too high or too low, the fan sensor is the problem, the main control board detection circuit is the problem, the communication problem between the outdoor unit and the indoor unit, the plug contact problem is poor, etc. If it only flashes a few times and does not light up, it is related to the power plug or socket. If it keeps flashing, you need to disconnect the cable and troubleshoot.

2. Power plug or socket failure

If the Midea air conditioner running light does not light up a few times, the possible reason is the plug or socket of the power supply, such as poor contact or the socket is out of power. It's also possible that the power circuit breaker is faulty. Workaround:

Check the plug and socket to make sure the power is OK and then try to turn it on. If these are still normal, it is time to check for other causes.

3. The wind speed is too high or too low

Too high or too low a voltage will cause the wind speed to be too high or too low, and it will also cause the running lights to blink all the time. Solution: Make sure the voltage is stable and normal, and then adjust the wind speed within the normal range.

4. Fan sensor failure:

If there is a problem with the built-in Hall sensor of the general fan, the running light will flash. Solution: You can replace the sensor first. If it returns to normal, if it is still not normal, you need to replace the fan.

5. The main control board detects the circuit fault

Solution: Check whether the Hall sensor detection circuit of the main control board is normal. If it is not normal and needs to be repaired in time, the main control board may need to be replaced.

If there is a connection failure between the outdoor unit and the indoor unit, if there is a problem with the connection between the external machine and the internal machine, the communication will fail. Solution: You can disconnect the connection cable of the internal and external units first, and then connect the indoor protection signal to the lead.

If the running lights return to normal, it means that the connecting cable is faulty, and the connecting cable can be connected.

Turn on the power plug of the air conditioner and restart it after 5-10 minutes, as it may be overload protection caused by voltage instability. If the problem still can't be turned on after restarting, you must contact the after-sales service department of Midea, or you can find an air conditioner repair point. It would be better to have a professional check it out and then solve it.

It may be due to the error of the factory parameters, or it may be caused by the unstable voltage; If the flashing light cannot be turned on, it needs to be sent to the manufacturer for repair.

It may be that the circuit is faulty, and it is best to press and hold the on/off key for about 10 seconds, and then it will automatically turn on for you.

The reason may be that the system is faulty, such as the wrong parameter setting at the factory, you can ask the manufacturer to send professional and technical personnel to redo the system

This is the formulation of the execution, there is a mess, after the reboot can be back to normal, it needs to be set up again.

Summary. Hello, dear, Midea air conditioner indicator flashing for the following reasons: (1) The air conditioner running light flashing is likely to be due to the inability to communicate normally between indoor and outdoor air conditioning equipment.

The reason may be that there is a magnetic field from the outside world that interferes with this, and the fault can be detected by the display board of the air conditioner. (2) When the current is overloaded, it will also cause the air conditioner to flash, sometimes the voltage in our home is too high and the air conditioner will be overloaded, which is the air conditioner will start the self-protection system, and the indicator light will keep flashing, and accompanied by the phenomenon of turning on and off. (3) When there are some faults or problems in our cooling or heating system, our air conditioning running lights will also keep flashing, which is to remind us that the air conditioner is faulty and we need to repair it in time.

When there is a problem with the heating and cooling system of the air conditioner, some strange phenomena will occur in the air conditioner.

Midea's air conditioner indicator light is flashing, what is the fault?

On July 14, 2020, the results of the 21st China Patent Award released by the State Intellectual Property Office showed that Midea's inverter air conditioning compressor technology won the award"China Patent Gold Award"。

Midea air conditioner running lights flashing on may have the following problems:

It may be that the voltage is too high or too low for device protection;

or indoor evaporator high temperature protection or low temperature protection;

It is recommended to wait for 5-10 minutes before restarting, if the problem can not be solved, it is recommended that you ask the after-sales service department of the machine to deal with it.

Common troubleshooting methods for air conditioners:

1.Small air outlet, poor refrigeration effect?

The outside ambient temperature is high, and there are more indoor personnel, and the air conditioner is working at full load.

If the power supply voltage is too low, the air conditioner is not easy to start, and it will stop or the fuse will blow after starting, so it is recommended that the user install a power regulator.

The air outlet of the air outlet is not large if the temperature does not drop in the strong cold block room, which is because the air filter has accumulated too much dust, and the filter is cleaned.

The thermostat is not properly adjusted.

Poor installation of air conditioners will lead to uneven indoor temperature or poor cooling effect.

2.Is the inverter air conditioner down normal:

When the user uses the air conditioner, the environmental insulation is very good, and the temperature of the room is very close to the set temperature, then the inverter air conditioner will be shut down. Because even if the inverter air conditioner runs at the lowest frequency, it will produce a certain amount of cooling, but at this time there is no energy loss in the room, according to the law of conservation of energy, the air conditioner will be shut down at this time.

3.The whole machine has no response when powered on and does not start.

First, ask the user to check whether the socket has electricity (you can plug in a fan, light and other simple equipment to try it). If not, please check the power supply of your home; If there is electricity in the socket and the power cord of the air conditioner is not damaged, it is a problem with the power supply circuit inside the air conditioner, and you need to contact the local outlet for on-site repair.

4.The air conditioner is normal, but the room temperature can't be lowered, how to solve it?

Whether the room temperature can be lowered is not only related to the quality of air conditioning and refrigeration, but also depends on the user's room heat insulation, good sealing, window area, orientation, floor location, number of door openings, number of people and other electrical appliances and heat sources, etc., and can measure the temperature difference between the air inlet and outlet, if the temperature difference is in the range of 10-13 degrees, there is no problem with the air conditioner. If the user does not accept this explanation, it can be suggested that the user install the air conditioner in a slightly smaller room or make up the price difference and replace it with a larger air conditioner.

If the Midea air conditioner running light flashes a few times and does not light up, the possible reason is the plug or socket of the power supply, such as poor contact or no power in the socket, etc., or it may be that the power circuit breaker is faulty.

If you don't listen to the flashing lights of the air conditioner, there should be no problem with this, as long as it can run the air conditioner, so you should not need to worry about it, you can use it with confidence.

Midea's air conditioner indicator light is flashing, what is the fault?

Hello dear, the reasons and methods are as follows: 1. If the power plug or socket is faulty, if the Midea air conditioner running light flashes a few times and it does not light up, the possible reason is the plug or socket problem of the power supply, such as poor contact or no power in the socket, etc., or it may be that the power circuit breaker is faulty. [Solution]: Check the plug and socket to make sure the power supply is normal, and then try to turn it on, if these are still normal, you need to check other reasons.

2. When the wind speed is too high or too low, it will cause the wind speed to be too high or too low, and it will also cause the running lights to flicker all the time. [Solution]: Make sure that the voltage is stable and normal, and then adjust the wind speed within the normal range.

3. If there is a problem with the built-in hall sensor of the fan, there will be a flashing running light. [Solution]: You can replace the sensor first, if it returns to normal, if it still does not return to normal, you need to replace the fan.

4. The main control board detection circuit is faulty [solution]: check whether the Hall sensor detection circuit of the main control board is normal, if it is not normal, it needs to be repaired in time, and the main control board may need to be replaced. 5. If there is a problem with the connection between the outdoor unit and the indoor unit, it will produce a communication failure.

Solution]: You can first disconnect the connection line of the internal and external machine, and then connect the indoor protection signal to the lead, if the running light returns to normal, it means that it is a connection line problem, and the wiring of the cherry hail bush can be connected.

First set the air conditioner operation mode to air supply with the remote control, turn on the machine to observe, after one minute the running light is flashing or normal, if the fault phenomenon does not change, that is, the indoor unit fan Hall sensing circuit circuit circuit detects the abnormal operation of the fan protection, possible failure:

1. The speed of the fan is too low or too high.

Solution: Adjust the fan speed to normal speed.

2. The built-in Hall sensor of the fan is faulty.

Solution: The sensing element needs to be replaced, repaired, or the fan replaced.

3. The main control board Hall sensing detection circuit is faulty.

Solution: The main control board needs to be repaired or replaced.

It is faulty, the indicator flashing is an alarm, the power failure is to reset the motherboard, and then turn on the air conditioner to work normally, indicating that the previous alarm is a soft fault and is generated from time to time. The specific faults need to be carefully checked to know.

Nowadays, air conditioners have anti-mildew function, after shutting down, the indoor unit will continue to work for a few minutes, and the water on the evaporator of the indoor unit will be dried before stopping.
