⚠️ BEFORE YOU START

Unplug the fridge if you’ll be removing interior panels. Move food to a cooler for anything longer than 30 minutes.

Step by step

1 Confirm the symptom

Water pooling under the crisper drawers on a weekly rhythm — or a sheet of ice on the freezer floor — is the defrost drain saying it’s blocked.
2 Find the drain hole

It’s at the low point of the freezer’s back interior, often under a plastic panel or behind the ice-maker area — a small hole or trough centered at the bottom.
3 Flush with hot water

Baster or funnel a few cups of hot (not boiling) water into the drain. If it gurgles through to the pan under the fridge, you’re winning; if it backs up, go to the next step.
4 Snake it gently

Feed a pipe cleaner or a length of trimmer line down the drain to break the gunk plug, then flush again until water runs freely.
5 Treat repeat offenders

Some models (many Samsungs and GEs) chronically re-freeze the drain: a cheap drain-heater clip that couples the drain to the defrost heater fixes it permanently.

🔧 WHEN TO CALL A PRO

If the drain area is buried behind an iced-over evaporator panel, you’re actually looking at a defrost system failure — thawing tells you nothing a tech can’t confirm properly with a meter. If you'd rather skip it entirely, find a refrigerator repair pro near you →
