What problems or symptoms may occur when the car compressor is broken? The simplest manifestation is that the air conditioning does not cool, because the air conditioning compressor plays a role in compressing and driving the refrigerant in the air conditioning system. Once the compressor fails, the most obvious manifestation is of course that the air conditioning does not cool. However, not cooling the air conditioning does not necessarily mean that the compressor is broken.

There are many factors that can cause the air conditioning to not cool. Can a car compressor be repaired if it is broken?How to determine if the car compressor is broken?

The simplest way to improve the cooling effect is to check if the engine speed increases when the air conditioning cooling switch is turned on.

1. If the air conditioning refrigeration engine speed increases when turned on, it indicates that the compressor control circuit is good; If the engine speed does not increase, it is either the compressor control circuit or the compressor electromagnetic clutch that is faulty.

2. Another possibility is that the engine speed has increased and the compressor clutch has also been engaged, but the compressor is locked, which means that the compressor is scrapped and useless. In addition, it is also possible that the refrigerant has entered the compressor or the oil seal has broken, causing incompressible liquid to enter the compressor and causing damage to the compressor piston.

The symptoms of a broken car air conditioning compressor are quite obvious. If the electromagnetic clutch of the compressor is broken, it can be replaced separately, but some repair shops require a complete replacement; If the piston of the compressor is damaged, the compressor can only be replaced. In addition, if the inlet and outlet valves of the compressor are damaged, the compressor can only be replaced.
