Clogged Drain Causes Leaking Refrigerators

Clogged Drain Causes Leaking Refrigerators

A clogged drain can cause a leaky refrigerator. This page will show you how to fix it and prevent it from happening again.

This is the leading cause of refrigerator leaks. Refrigerators that run can collect moisture in the freezer’s refrigeration lines.

This moisture freezes the coils. The refrigerator then defrosts every 6-48 hours to melt the ice formed during cooling cycles. The water flows into a drain and a pan, evaporating before the next defrost cycle.

If a drain is blocked, the water can return to your freezer. This water can then seep into the fresh food section and the floor.

If the water is not cared for, it will freeze in the air conduits and cause the refrigerator to stop cooling.

Side-by-side, bottom freezers and freezers stand-alone freezers will have water in their bottoms. Once the bottom has ice, water will escape through the door onto the floor.

Accessing The Drain

Depending on the model, reaching the bottom freezers may not be easy. To access models with a drawer-type door, you’ll need to take the door off the freezer.

After removing the door, remove the cover for the evaporator. A drain will be visible under the coils once the cover has been removed.

This can only be done if your refrigerator has a Calrod (metal) defrost heating element. If you are using a glass heater, do not attempt it.
