What's the problem with Midea's air conditioner turning on? What are the protection functions of the air conditioner
The reason why Midea's air conditioner doesn't respond when it's turned on
1. If there is anti cold air protection when the air conditioner is turned on at the beginning, there will be no wind coming in at this time. It needs to wait for a few minutes before the hot air blows out.
2. If the air conditioning screen appears garbled or freeze frame. So as long as you press the reset key to release, it may also be that the battery power is insufficient, and the air conditioner remote control cannot control the air conditioner to turn on, so you can replace the battery.
3. If the remote control display does not show temperature. The air conditioner should be in air supply or automatic mode, and the temperature will not be displayed at this time.
4. If the air conditioner receiver is damaged or damp, the air conditioner cannot accept the signal from the remote control, check the transmission of the remote control signal. You can use the digital camera (mobile phone can also be) to aim at the transmitter, press any key to see if there is red light in the camera.
5. The mode is incorrect or the temperature setting does not meet the startup conditions. The temperature set during refrigeration shall be lower than the indoor temperature, and the indoor temperature set during heating shall be higher than the indoor temperature.
Reason for power supply
1. The power supply is not connected or dead, the power wire socket is in poor contact or the power wire is aging.
2. The low power supply voltage may be due to the peak power consumption when using the air conditioner. It is recommended to use the voltage regulator to improve the use voltage of the air conditioner.
Air conditioning protection function
1. Delay protection. In order to protect the service life of the compressor, the control circuit of the air conditioning computer board is designed with a protection circuit, and the compressor can only be started after a delay of 3 minutes.
2. Prevent hot and cold air. When the air conditioner is heating, when the temperature of indoor coil unit is lower than a certain value, the internal unit will not operate. Generally, the internal unit will not work until it is preheated for 3-5 minutes.
3. The air conditioning computer program confusion causes the air conditioning to be unable to work normally.
4. Function lock protection. Some brands or models have child lock function. If the lock mode is in progress, no operation can be carried out, and only can be released according to the instructions. If the air conditioner still doesn't turn on due to the above problems, your air conditioner may have functional faults and should be repaired.
