If a residential split system with a replaced compressor is not cooling properly and the evaporator seems starved for refrigerant with a sweating liquid line leaving the dryer, what is the most likely cause?

Air in the system Debris from the burned out compressor has clogged the dryer Incorrect refrigerant charge A faulty expansion valve

Correct Answer:

Debris from the burned out compressor has clogged the dryer

Explanation:

The most likely cause of the issue described in the question is debris from the burned-out compressor clogging the dryer. When a compressor fails, it can send debris throughout the refrigeration system, which can accumulate and block the components, such as the dryer. This blockage can restrict the flow of refrigerant, causing the evaporator to appear starved and the liquid line leaving the dryer to sweat. This situation indicates a clog in the system rather than air in the system, an incorrect refrigerant charge, or a faulty expansion valve.
