where are the cooling coils on the newer compact refrigerators?
A refrigerator keeps things cool by circulating coolant between the condenser coil and the evaporator coil. A compressor is used to circulate the coolant. The condenser coil is located outside the refrigerator and the evaporator coil is on the inside. When you find that your refrigerator is no longer keeping cool inside, it may be a loss of coolant. Generally you can smell a coolant leak.
