A refrigerator is one of the few appliances in your home that runs continuously, day or night, keeping your food cold. If you consider how hard a refrigerator has to work, it is actually quite amazing that they break down so infrequently. On the rare occasion your refrigerator does stop working, you may face a high repair bill and the expense of replacing all your lost food. Have no fear! This article is here to tell you everything you need to know about repairing your refrigerator and freezer yourself. You might be surprised to learn that repairs are actually quite easy, requiring only a little knowledge about the appliance and a little patience. Let's get started with some basic information.
Refrigerators and freezers consist of two basic components: a condenser coil and an evaporator coil. A liquid coolant is circulated through these coils by a compressor and a motor. The refrigerant liquid is cooled in the condenser; it then flows to the evaporator. At the evaporator, the air in the unit is cooled by contact with the liquid-filled coil. The condenser of a refrigerator or freezer is the coil on the outside of the unit; the evaporator is the coil on the inside. The coolant is circulated through the system by a compressor.
