Common Causes of Automotive A/C Compressor Failure

1.Refrigerant Issues

Low refrigerant levels: Causes inadequate lubrication and overheating

Contaminated refrigerant: Moisture or air in system forms acids that damage components

Incorrect refrigerant charge: Both undercharging and overcharging strain the compressor

2.Lubrication Problems

Insufficient PAG oil: Leads to metal-on-metal contact and premature wear

Oil contamination: Dirt or moisture degrades lubricating properties

Wrong oil type: Incompatible viscosity or formulation causes lubrication failure

3.Electrical Failures

Faulty clutch coil: Prevents proper engagement/disengagement

Wiring issues: Short circuits or poor connections affect operation

Relay/switch failures: Cause irregular cycling or constant operation

4.Mechanical Wear

Bearing failure: Due to age, contamination or lack of lubrication

Seal leaks: Allow refrigerant and oil to escape

Internal component wear: Pistons, valves or scroll mechanisms degrade over time

5.Contamination

Debris in system: Metal particles from other failed components

Moisture ingress: Causes corrosion and acid formation

Dirt entry: During improper servicing procedures

6.Operating Conditions

Excessive heat: From clogged condenser or high ambient temperatures

Frequent short cycling: Due to electrical or pressure switch problems

Improper belt tension: Causes slippage or excessive load
