When a hermetic compressor "burns out", what is the main cause of contaminates forming?

The main cause of contaminants forming when a hermetic compressor "burns out" is the breakdown of oil and refrigerant. During normal operation, the oil in the compressor is crucial for lubrication and cooling, while the refrigerant facilitates the transfer of heat. However, when a compressor fails, usually due to overheating or wear, it can cause the oil to break down. This breakdown can result in the formation of carbon, sludge, and other contaminants. Additionally, the high temperatures resulting from a burnout can lead to chemical reactions that produce acids and other hazardous byproducts, further polluting the system.

These contaminants not only impair the efficiency of the compressor and other system components but can also lead to additional failures or costly repairs if not addressed. The breakdown of oil and refrigerant is a significant concern when a hermetic compressor fails, as it indicates a systemic issue that could affect the longevity and reliability of the refrigeration system itself.
