Who can tell me how to maintain Midea's air conditioner when it doesn't turn on?

Midea's air conditioner can't be turned on, Midea can't be turned on, and the air conditioner doesn't respond for the following reasons:

1, the screen appears garbled or frozen. Press the reset key to release, or the battery is low.

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

3. The receiver head is broken or can't work normally due to moisture. Check the transmission of remote control signal. Aim the digital camera (or mobile phone) at the transmitter and press any key to see if there is an infrared signal.

4. The mode is incorrect, or the temperature setting does not meet the starting 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 lead to short remote control distance or no remote control. It is recommended to take out the battery when not using the air conditioner, and reinstall or replace it when using it.

6. The power supply is not connected properly or there is no electricity, the power lead socket is in poor contact, or the power lead is thin or aging.

7. Low power supply voltage. Starting voltage of fixed frequency air conditioner: 187V, voltage fluctuation range v, starting voltage of variable frequency air conditioner: 156V, 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 printing machine, a protection circuit is designed in the control circuit of the air-conditioning computer board, and the printing machine is started after a delay of 3 minutes.

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

10, the computer program of the air conditioner is out of order, which makes the machine unable to perform the scheduled work.

1 1, function locking 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 instruction manual to unlock it.

If the air conditioner doesn't turn on after solving the above problems, your air conditioner may have a functional failure, so you have to find a master.

I hope I can help you, and I hope I can adopt it satisfactorily. Thank you.
