What are the reasons for the Baojun e300 air conditioner not cooling?

[DiVincent]

Baojun e300 air conditioner not cooling may have the following reasons: 1. Too much refrigerant: leading to decreased cooling effect. Excessive impurities in the refrigerant and refrigeration oil can cause slight blockages, resulting in insufficient cooling capacity. 2. Too little refrigerant: insufficient refrigerant leads to inadequate cooling capacity. A dirty condenser or a loose compressor drive belt can also cause the air conditioner not to cool. 3. Excessive impurities in the refrigerant and refrigeration oil: slight blockages can cause insufficient cooling capacity. If there are too many impurities in the refrigerant and refrigeration oil throughout the entire air conditioning system, the filter screen of the filter will inevitably become clogged, reducing the refrigerant's flow capacity, increasing resistance, and relatively decreasing the amount of refrigerant flowing to the expansion valve, thus resulting in insufficient cooling capacity.
