How do I stop water from collecting at the bottom of my fridge?

Preventing water from pooling and collecting at the bottom of your residential refrigerator fresh food compartment requires clearing a blocked defrost drain line. First, unplug the refrigerator from the electrical wall outlet and remove all food storage bins, shelves, and the lower freezer back access panel to expose the frozen drain trough beneath the evaporator coils. Second, use a hair dryer on a warm setting or squirt warm water down the drain hole using a turkey baster to melt any solid ice plug. Third, push a flexible nylon pipe cleaner or a piece of stiff wire gently down the drain opening to sweep away trapped food particles and algae slime. You can troubleshoot drainage flow easily. You can verify that your corrective action is successful when pouring a small cup of warm water into the drain trough results in water flowing unimpeded into the bottom evaporation pan without pooling.
