Why Does a Car Compressor Fail?
2 Answers
Introduction to the main causes of compressor damage: 1. The air conditioning system is not clean, and granular impurities are sucked into the compressor; 2. Excessive refrigerant or lubricating oil in the system causes "liquid hammer" damage to the compressor; 3. The compressor operates under long-term high temperature and high pressure harsh conditions; 4. Severe oil shortage in the compressor leads to excessive wear; 5. The electromagnetic clutch of the compressor slips, causing excessive friction temperature; 6. The power configuration of the compressor is too small. The following are the measures to avoid air conditioning compressor failures: 1. Avoid using the air conditioning system for a long time when the car is idling; 2. Ensure that the refrigerant is not overfilled during car air conditioning maintenance; 3. Do not continue to use the air conditioning system after any abnormality is detected.
Compressor failures typically occur under these circumstances: The most common issue is refrigerant leakage. A lack of refrigerant leads to poor lubrication inside the compressor, causing internal components to grind dry and eventually seize up. Another problem arises when moisture and contaminants enter the system, forming acidic substances that corrode seals and bearings. Electrical faults, such as short circuits or burnout in the electromagnetic clutch coil, can also prevent the compressor from engaging, rendering it inoperative. Additionally, prolonged idling with the air conditioning on can cause excessive temperatures, placing significant strain on the compressor. Furthermore, belts that are too loose or too tight can adversely affect the compressor's performance, particularly in older vehicle models where such issues are more prevalent. Regularly checking refrigerant pressure and cleaning the system's pipelines are effective preventive measures. Don't wait until the air conditioning stops cooling to think about repairs.
