What are the reasons for a car compressor not working?
2 Answers
There are several reasons why a car compressor may not work: Reason 1: Severe internal wear of the compressor leads to its inability to function properly. Since the compressor plays a crucial role in the air conditioning system, its main tasks are compressing and transporting refrigerant, which causes the compressor to operate at high speeds for extended periods. This is one of the reasons why the compressor may fail to work properly. Reason 2: The compressor is primarily used to compress and transport refrigerant. If there is an issue, check for any refrigerant leaks. If there is no compression or transportation of refrigerant, the compressor naturally won't work. Reason 3: A fault in the electrical system can effectively prevent the car's air conditioning compressor from working properly. Therefore, the owner can check if the circuit is unobstructed and inspect the temperature sensor and solenoid valve.
Last time my car's air conditioning suddenly stopped cooling, it took me a long time to figure out the problem. The most common issue is the refrigerant leaking out, causing insufficient pressure so the compressor won't start at all. You also need to check if the air conditioning circuit fuse is blown - my old car was out of commission for a week because of a blown fuse. If the belt is loose or broken, the compressor won't turn either; you can tell just by touching it. Sensors are crucial too - if the high or low pressure switches fail, the compressor won't receive the signal. The most frustrating is when the compressor itself fails, with the electromagnetic clutch not engaging or internal seizure. Oh, and loose or aged wiring connectors can also make the compressor stop working - you'll need to carefully inspect every connector.
