Abstract: A clogged refrigerator drain is a common, often overlooked, household issue that leads to water leakage, frost buildup, and spoiled food. This paper outlines the causes, symptoms, and step-by-step methods for safely unclogging a refrigerator drain line, emphasizing both basic tools and preventive maintenance.
Modern frost-free refrigerators periodically defrost. The resulting water flows down a channel to a drain hole at the back of the fresh food compartment, through a flexible tube, and into a drip pan under the appliance, where it evaporates. When this drain line clogs, water backs up and leaks onto the floor or freezes inside the freezer compartment. how to unclog fridge drain
