Refrigerator Leaking Water: A Homeowner's Guide

Finding water pooling under your refrigerator, or noticing it collecting inside the crisper drawers, is one of those problems that looks worse than it usually is. Most cases trace back to one of three specific points, and figuring out which one saves a lot of unnecessary guesswork.

Where the Water Is Coming From

Refrigerators generate condensation as part of normal operation and are designed to drain it away through a small channel at the back of the interior, down a tube, into a pan underneath the unit where it evaporates. A leak means something in that path has gone wrong - most often a blockage, sometimes a physical break.

The Three Usual Suspects

• A blocked defrost drain - food debris or a build-up of ice can plug the small drain hole at the back interior wall, so melted frost backs up and overflows inside instead of draining away
• A damaged or dislodged drain pan underneath the fridge, which can crack or slip out of position over time
• A worn door gasket letting in humid air, which condenses and adds to frost build-up that eventually melts and overflows

What to Check Yourself

Look at the back interior wall of the fridge for visible ice blocking the drain hole - this is the single most common cause and is often fixable just by clearing the ice with warm water and a turkey baster or similar. Confirm the fridge is standing level, since a tilt can cause water to pool in the wrong spot even with a working drain. Finally, check underneath the unit for a drain pan that has slipped out of place.
