Why is the air conditioning not cooling at idle speed?

[DelJosie]

The reasons why the air conditioning is not cooling at idle speed are: 1. The refrigerant in the air conditioning system has leaked completely, resulting in insufficient refrigerant, so the air conditioning does not cool. 2. Some components in the air conditioning system, such as the pipelines, air conditioning pump, condenser, and evaporator box, may be damaged, causing refrigerant leakage. Internal damage to the air conditioning pump can prevent it from starting the cooling effect. Generally, a damaged air conditioning pump will produce abnormal noises, so check the air conditioning pump and replace it if it is damaged. 3. The condenser fins in the air conditioning system are too dirty, causing the pressure and temperature of the air conditioning system to be too high. To protect the air conditioning system, the air conditioning pump stops working, so the air conditioning does not cool. You can use a high-pressure water gun to clean the condenser fins and then dry them with a high-pressure air gun.
