Often, customers expect to use the fixed refrigerator for a long time without any troubles. Still, after the first breakdown you have to reconsider maintenance and arrange a diagnostic on a regular basis. This case demanded a repeated repair visit after replacement of the compressor one year ago. A compressor is the heart of the refrigeration cycle. When it does not work properly then the entire cooling process does not even start. The job of the compressor is to compress the refrigerant from a low pressure cool vapor into high pressure hot vapors. This compressed refrigerant in the form of hot high pressure vapors then flows through the condenser where it gets condensed into high pressure liquid. This liquid then flows through the evaporator coil where it evaporates and cools down to a low pressure vapor. Air flows over the cooling coils and keeps the refrigerator cool. So when the compressor is out of order, this refrigeration cycle does not even start. When high pressure hot refrigerant condenses in the condenser, a lot of heat is dissipated during this conversion. But when the condenser coil is dirty and loaded with debris, heat does not flow out of the coils properly. This heat stays inside the refrigerator and reduces the cooling. In your refrigerator there is a condenser fan that forces hot air out of the refrigerator. So when it goes bad the hot air cannot be released into the room and remains inside the refrigerator. Because of this the temperature inside the refrigerator shoots up. A faulty fan motor or defective fan blades prevent the condenser fan from working properly. After checking previously repaired parts, condenser coils were cleaned. The owner got a recommendation to check the unit every six months and contact a support team when it would be needed.
