By following this guide, you can fix a clogged defrost drain in about an hour, save a costly service call, and extend the life of your refrigerator.

If water pressure doesn't work, the clog is likely solid debris (like a pea or a chunk of hardened ketchup—don’t ask us how it got there).

The water has to go somewhere. Pull your fridge away from the wall (slowly, to avoid kinking the water line). You should see a shallow pan sitting on top of the motor.

Moisture or puddles under the vegetable crisper drawers or on the floor in front of the fridge.

Unplug the appliance from the wall outlet. This eliminates the risk of electric shock, especially since you’ll be working with water near electrical components. If you can’t easily move the fridge, just ensure the power is off.
