The compressor is the center of the refrigeration system and is the most hardworking components of the refrigerating system. The compressor is the most hardworking components of the refrigerating system, this component can absorb temperature running into hundreds of degrees and more hundreds per square inch of internal pressure. Despite this, it thrives on few ounces of lubricant to keep the moving parts out of friction but if the lubricant is lost to leakage or is contaminated the compressor may soon be shutting down.
Ordinarily a failed compressor does not serve its purpose (cooling) however a compressor might spoilt from its internal components. This could be when the clutch does not turn when energized. This results in noise from the belt drive, belt being broken or derailed
A compressor may fail too when it loses lubricant. This situation is witnessed when there is a leakage of refrigerant and oil in the system. Noted place of leakage could be through hoses and pipes and their links i.e. O-rings as well as flange gasket, the evaporator, condenser etc.
A compressor with leakage maybe caused by bad reed valves, worn piston rings or damage in the cylinder.
N/B: A failed compressor may still be working but would be producing severe knocking sound. This fauls could be caused by unwanted air in the vacuum system. The system should be bled and a new refrigerant refilled.
