Self defrosting refrigerators as well as freezers all have a defrost drain system. This drain system can become plugged or frozen causing defrost drain water to back up into the refrigerator or freezer compartment. The water may gather under the crisper drawers on top freezer models. On side by side, bottom or stand alone freezers ice will build up in the freezer at the bottom and eventually leak out the door.
Plugged Defrost Drain - Freezer on Top (Water under the crisper drawers)
At the top of the refrigerator next to the temperature controls there usually is a cup-like part that carries the defrost drain water into a tube and out the back of the refrigerator to a defrost drain pan behind the unit. Pull the cup out of the tube and clean the cup with hot water and soap. If there is no cup, pull the refrigerator out away from the wall, go behind it and disconnect the drain tube to clear it. If the drain tube is not accessible from the back or the drain can not be cleared from there the main back panel in the freezer can be removed to access, thaw and flush out the drain under the cooling coil.
Use a turkey baster to flush HOT water into the tube to clear any obstruction. The water squirted into the tube should end up in the defrost drain pan.
If the tube will not clear with hot water try blowing it out with compressed air.
Put the cup back on and make sure it is all the way on or in the tube.
Plugged Defrost Drain - Side By Side, Bottom-Freezer Refrigerator or Stand Alone Freezer
The defrost drain pan is located at the bottom of the freezer compartment behind the back wall of the freezer. On some models, the pan is accessible without removing the back panel and others are not. After you get to the defrost drain pan use a hair dryer to melt the ice from the pan.
Once the ice is removed use a turkey baster to squirt HOT water into the drain hole to clear the drain.
When the drain is clear you should hear or see the water you are squirting into the hole enter the pan under or behind the refrigerator.
