What happens when a compressor overheats?
A compressor that overheats can still operate and provide cooling or heating but if the temperature inside the compressor rises too high then the oil in the compressor can break down and reduce the lubrication and cooling effect the oil has inside the compressor for proper and necessary lubrication. This leads to possible mechanical failure and other problems that will occur to the compressor and in the refrigeration system that results from compressor overheating. When the oil becomes overheated it changes chemically. Through a lack of lubricating and cooling it becomes like an acid when the oil overheats. This eats away at the windings and will cause compressor failure.

What is the purpose of a compressor in an A/C unit?
Without getting into the technical stuff, the compressor in an A/C serves a two-fold purpose. Located in the outside unit along with the condensing coil and fan, it pumps refrigerant through your A/C coils and lines and puts gaseous, heat-filled refrigerant under pressure in the condensing coil. When this happens, the refrigerant is converted back into a liquid, releasing heat energy into the surrounding air. When the compressor malfunctions, it can cripple both of these essential functions.
Can an overheating compressor cause a breakdown?
But if the overheating continues or gets worse, it will result in a potentially expensive system breakdown. Having to replace the compressor is among the most expensive fixes for a central A/C.
