Why Is There Water Under My Fridge's Crisper Drawer?

Where that water is supposed to go

Frost-free refrigerators melt the frost off their evaporator coil on a regular cycle. That meltwater runs into a trough and down a drain tube to a pan under the fridge, where it evaporates. When the water can't get down that drain, it has to go somewhere — and very often that somewhere is the floor of the fresh-food compartment, under the crisper or deli drawer.

The most common cause: a clogged or frozen defrost drain

Food particles, debris, or mold can block the drain opening, or water in the tube can freeze and form an ice plug. Either way, meltwater backs up. A frozen drain is especially common on some models where the drain runs close to the cold evaporator, and it tends to come back even after it's cleared once, because the conditions that froze it haven't changed.

Why clearing it yourself sometimes doesn't last

Many owners clear a drain with warm water and it works for a few weeks, then the puddle returns. When that happens it usually means one of these:

• The drain freezes rather than clogs, so it re-forms until the underlying cause is addressed
• A drain heater or clip that keeps the drain from freezing has failed or is missing
• The defrost system isn't working properly, so ice builds up on the coil and meltwater arrives in larger amounts than the drain handles
• The drain was only partly cleared and debris further down the tube is still there

Other causes worth ruling out

• Water filter or water line. On fridges with a dispenser or ice maker, a cracked filter housing, loose fitting, or damaged internal water reservoir can leak into the fresh-food section.
• Door seal. A seal that isn't closing fully lets warm, humid air in; the moisture condenses inside and collects at the bottom.
• Level. A fridge that isn't tilted slightly backward can let water sit rather than run toward the drain.
• Food spills. Worth checking first — a leaking container can look exactly like a drain problem.

What you can safely check

Empty the drawers and dry the area, then watch where water reappears and how fast. Check that the door closes and seals fully, and look for a leaking container or a damp spot near the water filter. Don't chip at ice on the back panel with anything sharp; the coil and refrigerant lines sit right behind it, and puncturing them turns a drain problem into a sealed-system repair.

When to call for a repair

If the water keeps returning, if you see frost building up on the back wall of the freezer, or if the fridge is also struggling to hold temperature, the defrost system is the likely story and it needs proper diagnosis. Getting inside the evaporator panel means handling components near the refrigerant lines, which is a job for a technician. We'll find out whether it's a clogged drain, a frozen one, or a defrost fault causing it.
