What are the methods for repairing air conditioning compressor failures?

There are several main methods for repairing air conditioning compressor failures, which are: 1. Tapping method. After turning on the power, use a wooden hammer to tap the lower half of the compressor to make the stuck internal parts vibrate and start operating. 2. High-voltage starting method. You can use a voltage regulator to increase the power supply voltage before starting. 3. Capacitor starting method. You can connect a capacitor with a larger capacitance than the original one to the circuit to start. 4. Pressure relief method. Start the compressor after completely releasing the refrigerant from the system. The main symptoms of air conditioning compressor failures are: 1. Short circuit, open circuit of the winding, and winding touching the shell grounding. 2. Vibration and noise of the compressor. 3. The suction and exhaust valves of the compressor not closing tightly. 4. Compressor shaft seizure and cylinder sticking. 5. Damage to the thermal protector.
Last time my AC compressor had an issue, the car would buzz loudly when I turned on the cold air, and it didn't cool at all. At first, I thought it was low on refrigerant, but adding more didn't help. After inspection, it turned out the compressor clutch was worn out and needed replacement. The steps are simple: first, turn off the engine and disconnect the battery for safety. Use a pressure gauge to test the system for leaks. If there's a leak, replace the compressor seals or the entire unit. If you're doing it yourself, buy a compressor and tools—there are tutorials online—but be careful not to touch the refrigerant, as it's hazardous. Experience tells me it's best to take the car to a professional shop; they can also check if the lines are clogged. The whole repair cost a few hundred bucks, but it was worth the peace of mind. When driving normally, avoid aggressive AC start-stop cycles to extend the compressor's lifespan.
When I encountered an air conditioning compressor failure, I was quite confused. After starting the car, the cold air wouldn't come out, and there was a strange smell. The first step is not to panic and try fixing it yourself randomly. First, check if the fuse or relay is burnt out, and simply replace them to see if it works. If the issue lies with the compressor itself, such as internal wear causing insufficient cooling, you'll need to use diagnostic tools to check for leaks or pressure readings. When I went to the repair shop, the technician replaced the entire compressor unit for me. It cost some money, but the effect was immediate. They also mentioned checking if the refrigerant pipes are aging or leaking, as this could easily lead to a recurrence. As a car owner, I suggest that beginners avoid tinkering blindly and instead seek experienced professionals for quicker and safer repairs. Remember, regular maintenance of the air conditioning system can prevent these troubles.
The compressor is broken, and the non-cooling air conditioning is really annoying. The inspection method isn't difficult: first check if there's any abnormal noise or vibration when the compressor is running. If so, internal parts might be damaged. For repairs, simple tasks like replacing the compressor belt or bearings can be done yourself to save a few hundred bucks. However, for complex jobs like replacing the entire compressor refrigeration unit, it's best to consult an expert. Last time, I opted for convenience and bought a new compressor to install directly, ensuring the system was properly vacuumed and refilled with refrigerant. Through the whole process, I realized prevention is key—cleaning the condenser and checking refrigerant levels every six months can significantly reduce the chances of failure.
