What is the reason why the Midea air conditioner compressor does not start?

Midea's air conditioning compressor does not start, which may be caused by long-term operation under the lack of Freon. It may also be that the air in the system is not discharged clean during installation, and there is ice blockage from time to time, and the load on the compressor increases. It may also be because the power supply is not properly connected or out of power, the power lead socket is not in good contact, or the power lead wire diameter is thin or aging, and the power supply voltage is low.

The compressor temperature increases due to the increase of shrinkage load, and the refrigeration oil will deteriorate for a long time at high temperature, which can not play the role of lubrication and cooling, which will further increase the temperature of the compressor, and the coil will be reduced due to high temperature insulation, resulting in damage to the compressor.

Summary. Dear, hello, very happy for your question, 1. The most important reason for the air conditioner not to refrigerate may be that the freon pressure value inside the air conditioner is too low, in this case, we can timely detect whether the freon of the air conditioner is within the normal pressure value, if the freon is too low, you can contact a professional master to help add freon. 2. The normal electric pressure value of the air conditioner is above 187 volts, if the voltage rate of the air conditioner is lower than 187 volts, it will also affect the air outlet of the air conditioner and the refrigeration effect of the air conditioner.

3. The power of the air conditioner is also proportional to the use of space, if the use of space is relatively large, we must choose the air conditioner with relatively large power, otherwise it will affect the refrigeration effect of the air conditioner, in addition, after the air conditioner is used for a long time, the internal filter screen will accumulate a lot of dust, so it is also very necessary to clean the dust on the filter screen in time.

4. Air conditioning in summer is the peak period of use, the outdoor temperature in summer is generally relatively high, when encountering the problem of air conditioning is not refrigerated, you also need to consider whether the temperature difference between outdoor and indoor temperature is relatively large, indoor and outdoor temperature difference is relatively large, the refrigeration efficiency of air conditioning will be reduced a lot.

The reason why the Midea air conditioner does not start the outdoor unit:

1. The reason for the voltage, the reason for the insufficient voltage is an important reason why the external unit does not start, if the air conditioner can not be turned on, it is necessary to check whether the external power supply is electric or whether the voltage reaches the rated voltage. If it is not the reason for low voltage, please check whether the indoor and outdoor units are connected correctly, whether the wires are aging, and whether the wiring of the main board of the indoor unit is correct, otherwise replace the internal motherboard;

2. If the indoor unit has not had a good refrigeration effect and slow cooling, and the outdoor unit does not start, it may be caused by the lack of fluorine in the air conditioner.

3. If your air conditioner is newly installed soon, it may be that the air in the system is not discharged clean when the air conditioner is installed, resulting in the phenomenon of ice blockage in the air conditioning system, resulting in an increase in the load of the compressor and an increase in temperature.

4. In addition, there may be communication problems, the outdoor electromechanical car source is normal, and the alarm of the red indicator light appears, at this time, it is necessary to check the communication between the air conditioner and the outside unit.
