What is the defrost drain in a refrigerator?
The defrost drain in a refrigerator is a channel that allows excess water generated during the defrosting process to exit the appliance. When the refrigerator cools down, moisture in the air can condense and form water droplets, particularly in the freezer compartment. Heating elements or fans work to melt the frost built up on the evaporator coils, and this meltwater is directed down the defrost drain, preventing it from pooling inside the fridge.
If the defrost drain is functioning properly, it ensures that water flows to a drainage pan located at the bottom of the fridge or into the outside environment. If the drain becomes clogged or obstructed, it can lead to water buildup inside the refrigerator and potentially damage its components or create mold growth.
