Why does the car air conditioning stop cooling after half an hour of operation?
1 Answers
Here are the reasons why the car air conditioning stops cooling after half an hour of operation: Internal damage: Severe internal wear of the compressor, leading to its inability to function properly. Oil stains: Oil stains at connection points or seams indicate refrigerant leakage in those areas, requiring re-tightening or replacement of related components. Electrical system malfunction: Electrical system failures causing the car air conditioning compressor to malfunction are also very common. You can check if the circuit is unobstructed, inspect the temperature sensor solenoid valve, and other potential fault causes. Low-pressure gauge reading significantly below normal: The surface temperature of the compressor suction pipe is lower than normal, appearing damp and icy (commonly known as sweating).
