most hermetic compressor motors fail due to excessive heat caused by high amp draw or: select one: a. liquid…

Brief Explanations:

Liquid slugging occurs when liquid refrigerant enters the compressor instead of vapor. This can cause mechanical damage and over - heating, leading to motor failure. Excessive oil may cause lubrication issues but not typically over - heating like liquid slugging. Low refrigerant charge usually results in reduced cooling capacity rather than over - heating the motor. Improper oil change mainly affects lubrication quality, not directly related to over - heating due to high amp draw.

Answer:

A. Liquid slugging of the compressor.
