The refrigerator defrost cycle is the process that allows the thermometer of the refrigerator to cycle on and off in order to control temperature settings. This process occurs as a wire detector reacts to the changing temperatures as the freezer goes from room temperature down to below freezing.
One of the most important things to consider when running through the freezer defrost cycle is whether or not you have thoroughly cleaned out the top and bottom of your refrigerator. Defrosting a freezer plays an important role in maintaining the longevity of the appliance. Routine maintenance and defrosting of the freezer gives you the opportunity to then go in and clean out a variety of the vents that can get clogged after continual use, especially in households that may have pets.
Even though it takes a certain amount of time and consideration when going through the defrost cycle, it is not necessarily a difficult thing to accomplish by yourself. Each refrigerator may have specifications relative to the model. Be sure to check your user manual and validate the procedure for the given model that you have in your home. Taking this extra consideration can help save you time in the long run.
