Quick service tip: Handling hermetic compressor burnouts
A common cause of compressor failures that we must contend with is the burnout of the motor in hermetically sealed compressors. This failure is generally the result of a reduction in the dielectric integrity (resistance) of the motor winding insulation.
In air conditioning systems, when excessively high temperatures occur in the refrigerant system, the thermal stability point of the refrigerant may be reached. When this happens, the refrigerant may break down.
