Magger reason of refrigerator copresooor failure
The major cause of refrigerator compressor failure is overheating, often triggered by a lack of proper lubrication or a poor compression ratio. When a compressor overheats, it can seize moving parts or degrade the oil, accelerating internal wear.
Top Causes of Compressor Failure
- Lack of Lubrication: Compressors require oil to keep their moving parts smooth. If oil leaks or degrades, friction causes the compressor to overheat and eventually seize.
- Dirty or Blocked Condenser Coils: Coils caked with dirt cannot efficiently dissipate heat. This forces the compressor to work harder and run longer to cool the fridge, leading to thermal breakdown.
- Electrical Issues: Power surges, voltage fluctuations, or faulty starting components (like a broken start capacitor or relay) can prevent the compressor from starting, causing it to draw excessive current and overheat.
- Refrigerant Issues: Leaks or an incorrect refrigerant charge make the compressor work under abnormal pressure, generating severe internal heat.
How to Diagnose
If your compressor fails to start or your fridge stops cooling, check the cheaper, external components before assuming the compressor is dead:
- Clean the Condenser Coils: Use a vacuum and a soft brush to remove dust and debris.
- Test the Start Relay and Capacitor: Listen for a “clicking” sound. A faulty relay or capacitor can prevent the compressor from receiving the kick it needs to turn on, even if the compressor is perfectly fine.
- Check for Shorts: A technician can test the compressor’s motor windings with a multimeter to check for an electrical short.
