What Causes the Compressor to Fail?

[McAlan]

Compressor damage may be caused by a faulty air conditioning pipeline pressure switch or poor heat dissipation performance of the air conditioning condenser. Below are the symptoms associated with compressor failure: 1. Car air conditioning not cooling: Since the compressor plays a crucial role in compressing and driving the refrigerant in the air conditioning system, the most obvious sign of compressor failure is the air conditioning not cooling. However, it's important to note that there are many other factors that can also cause car air conditioning not to cool. 2. No increase in engine RPM: If the engine RPM increases, it indicates that the compressor control circuit is functioning properly; if the engine RPM does not increase, it suggests an abnormality in the compressor control circuit or a possible fault in the compressor electromagnetic clutch. This issue can be resolved through inspection and replacement. 3. Engine stalling: This is a typical symptom of a seized air conditioning compressor, usually caused by poor lubrication or lack of lubricating oil leading to friction. In the worst-case scenario of a seized compressor, the entire assembly may need to be replaced.
