How To Clean Refrigerator Condenser Coils



The condenser coils at the bottom of the refrigerator accumulate dust during normal operation. When the dust coats the heat exchanger coils of the condenser, the coils can't properly cool down the refrigerant in the refrigeration cycle. The result is decreased efficiency and poor cooling performance in the refrigerator. The following refrigerator repair guide shows how to clean the refrigerator condenser coils.
