What is a defrost drain in a refrigerator?
The defrost drain in a refrigerator is a small channel that allows water created from melting ice during the defrost cycle to exit the appliance. When the refrigerator operates, it generates frost on the evaporator coils, and periodic defrosting melts this frost. The water needs a way to escape; that’s where the defrost drain comes in.
If the drain becomes clogged or blocked, it can lead to excess water buildup, which might then leak into the refrigerator or freezer compartments. Understanding how this drain works is essential for maintaining your refrigerator’s optimal performance and preventing common issues like water pooling inside the appliance.
How can I locate the defrost drain in my refrigerator?
Locating the defrost drain typically involves searching for it at the back of the refrigerator or freezer compartment. It is usually situated near the bottom of the appliance and can be found by removing any food items from the shelf just above.
