Should the car air conditioning compressor be repaired or replaced if it's broken?
1 Answers
If the compressor is only stuck due to poor lubrication or lack of lubrication, has minor refrigerant leakage, or issues like slipping and abnormal noise, repair can be considered. Otherwise, if the compressor has severe leakage or the electromagnetic clutch is burned out, it is generally recommended to replace it directly, as the repair work would otherwise be more extensive. Below is additional information on reasons why a car air conditioning compressor may not work: 1. Circuit system failure: Short circuits or open circuits in the circuit directly cut off the power transmission path, preventing the electromagnetic clutch from properly controlling the compressor's operation. 2. Lack of refrigerant: Refrigerant and refrigeration oil are mutually soluble and circulate back to the compressor through the system. If the Freon in the refrigerant is depleted, it will lead to insufficient oil return, reducing the compressor's lubrication effect and causing it to seize and fail. 3. Mechanical wear of the compressor: Long-term operation under high-speed load conditions may cause premature mechanical wear of compressor components, rendering it inoperable. 4. Over-tightened drive belt: An over-tightened drive belt can directly cause the compressor to seize and stop running, so it's important to regularly check the belt's tension. Conversely, if the belt is too loose, it will cause the compressor's power transmission to slip, resulting in intermittent cooling and reduced performance.
