Question 105Refrigeration & AC - QMED

The correct answer is B) Sweating of the compressor crankcase. Sweating of the compressor crankcase is an indication of an excessive amount of refrigerant circulating through the system. When there is too much refrigerant, it can cause the compressor crankcase to become cold, leading to condensation and "sweating" on the outside of the crankcase. This excess refrigerant in the system indicates a problem that needs to be addressed. The other options are not directly related to an excessive refrigerant charge. Weeping of the purge valve (A) and frosting of the evaporator (C) can occur for other reasons, while a colder than normal solenoid valve (D) is not necessarily an indication of an excessive refrigerant charge.
