There may be several reasons for not cooling.

1, fluorine deficiency, many air conditioners, whether Gree air conditioners or other air conditioners, may have this situation. As long as the air conditioner is used for a long time, the air conditioner is short of fluorine, which leads to the decrease of refrigeration capacity or no refrigeration. This is the most common reason, which is why the old air conditioner should be fluoridated to improve the refrigeration capacity.

2. Insufficient power supply voltage: the power supply voltage is uncertain, and it often fails to reach the normal voltage, especially during the peak period of power consumption. Of course, this problem is obviously not solved by a skilled air-conditioning maintenance master. We must solve this problem from the perspective of providing stable voltage.

3. Insufficient air conditioning power: This is also one of the common reasons for not cooling, but there are many reasons for not cooling. Low-power air conditioning tubes are large planes or rooms with the size of the surface of the object, and some air conditioning powers seem to match the size of the room plane or the surface of the object.

4. The filter screen of air conditioner will naturally get dirty after being used for a long time. If your home is an old air conditioner, the air conditioner filter has not been cleaned for a long time. If the cooling capacity of your home is not good, you may wish to remove the air conditioning filter and clean it, or update a new air conditioning filter;

5. If the outdoor unit of the air conditioner is in a ventilated place or not, the borrowing environment temperature is very high, and the outdoor unit temperature of the air conditioner is too high, and the air conditioning and refrigeration will definitely be affected;

6. Some people use the air conditioner well, and suddenly one day it doesn't cool, and the air conditioner doesn't even work. You might as well check the power cord of the air conditioner, whether it is connected to the power supply or not. The air conditioner will work only when it is powered on normally;

If you don't know how to maintain it, you can go to Wancheng commercial equipment maintenance official and find a nearby master to check.
