Goods Picture
Common Causes of Automobile A/C Compressor Failure
1. Lack of Lubrication (Oil Starvation)
Cause: Insufficient or degraded compressor oil (PAG or ester oil) leads to increased friction and wear.
Result: Seized pistons, bearing failure, or complete compressor lock-up.
2. Refrigerant Leaks
Cause: Damaged seals, O-rings, or cracks in hoses/components allow refrigerant (R134a or R1234yf) to escape.
Result: Low refrigerant levels cause poor cooling and compressor overheating due to lack of proper circulation.
3. Contamination in the System
Cause: Dirt, metal shavings, or moisture entering the A/C system (often from improper repairs).
Result: Clogged expansion valves, damaged compressor internals, or acidic corrosion from moisture mixing with refrigerant.
4. Electrical or Clutch Failure
Cause: Faulty wiring, blown fuses, weak clutch coil, or a malfunctioning relay.
Result: The compressor clutch fails to engage, preventing the A/C from functioning.
5. Overheating & Excessive Pressure
Cause: Blocked condenser, faulty cooling fan, or overcharged refrigerant.
Result: High pressure strains the compressor, leading to seal failure or mechanical damage.
6. Improper Installation or Repair
Cause: Incorrect belt tension, wrong oil type, or air/moisture left in the system after servicing.
Result: Premature wear, noise, or sudden compressor failure.
7. Normal Wear & Tear
Cause: Aging components (seals, bearings, valves) deteriorate over time.
Result: Gradual loss of efficiency, strange noises, or complete breakdown.
