What are the symptoms of a faulty car air conditioning condenser?

[DanielAnn]

When a car air conditioning condenser is damaged, the following symptoms may occur: 1. Air conditioning not cooling: The car air conditioner fails to cool. The cooling efficiency of the air conditioner is closely related to the cleanliness of the condenser's cooling fins. Dust and debris covering the condenser's surface can reduce its heat dissipation efficiency. Upon restarting, the pressure in the air conditioning system increases, leading to overheating, which can severely affect the compressor and related components. Therefore, maintaining the cleanliness of the condenser's surface is crucial to ensure the proper functioning of the entire air conditioning system. 2. Oil traces at leakage points: Condenser leaks are usually visible externally, such as scratches or impacts, with oil traces appearing at the leakage points. Evaporator leaks, due to lower pressure and condensation on the outer surface, are often hidden inside the evaporator box and are generally harder to detect. Leak testing for condensers and evaporators is typically conducted through a pressure test (pressure test), with test pressures of 2.0-2.4 MPa for condensers and 1.2 MPa for evaporators.
