Why Won't the Car Air Conditioning Compressor Start?

[SanCarlos]

Detailed reasons and solutions for car air conditioning compressor failure to start are as follows: 1. Severe internal wear of the compressor, leading to malfunction: Check the throttle valve position for iron filings. Excessive filings indicate compressor wear, necessitating replacement of a new air conditioning compressor. Solution: Replace with a new air conditioning compressor. 2. Insufficient refrigerant (Freon) in the car air conditioning system. Solution: Replenish refrigerant. 3. Fault in the car's electrical system: Requires circuit inspection. Solution: Inspect and repair the circuit. 4. Abnormal pressure in the car air conditioning system: Blockage or leakage in the air conditioning pipes can cause abnormal system pressure. Solution: Inspect and repair the air conditioning pipes. 5. Insufficient refrigerant in the car air conditioning compressor: Depletion of Freon in the refrigerant affects insufficient return of refrigeration oil, reducing compressor lubrication and causing jamming or damage. Solution: Replenish refrigerant.
