What is the reason why the air conditioner doesn't cool?

There are many reasons why air conditioners do not cool. The following are some common reasons why air conditioners don't cool:

First, check whether there is electricity and whether the power supply is connected;

Then check whether the air conditioner is in a cooling working state;

Indoor units (evaporator, fan blades, filter screen, etc.) are blocked. If this problem is cleaned up, it can be solved.

If it still doesn't work, check whether the compressor works. Generally, there are several situations that will cause the compressor not to work: the external temperature is too high or the heat dissipation is not good, and the compressor is overheated. In this case, we should consider moving the plane. The evaporator of the external machine is too dirty and the compressor doesn't work. Clean, but it is best to ask professionals to clean;

Whether there is a shortage of refrigerant requires professional inspection;

The electronic component is out of order.
