Refrigerators remove defrosted water to a drain pan under the evaporator coil through a plastic tube. But, when the drain tube or hole becomes clogged, it leaks water into your refrigerator or freezer. Luckily, cleaning the drain pipe takes little time and tools.

Step 1 – Unplugging the Refrigerator

Check out fridge drain pipes on Amazon.

First, turn off the power supply or unplug the refrigerator to avoid electrical shock when completing the following steps.

Step 2 – Locating the Drain Hole

Next, locate the drain hole. Generally, the drain hole is located at the bottom of your fridge. For better access, you can always remove the crisper drawers. If you cannot locate your fridge’s drain hole, check your manual for its location.

Step 3 – Unclogging the Hole

To unclog the hole, insert a plumbing snake into it, or create your own, and push it up and down. Once you’ve done this a few times, you can take the snake out of the hole.

Step 4 – Washing the Drain Hole

To clean the drain hole, pour about 1 teaspoon of baking soda down it, followed by 2 cups of warm water from a basting syringe.

Step 5 – Emptying the Solution From the Pan

Next, take off your fridge’s front grill plate to locate the drain pan, where the drain pipe empties its contents.

Empty the drain pan of the baking soda solution, and clean the pan with warm water and a clean rag. If you see any mold or mildew, you should remove it with a cleaning agent like vinegar. Once it’s clean, you can replace it and the front grill plate. You can now turn the fridge’s electricity back on.

Step 6 – Repeating the Process

To prevent your drain from being clogged again, clean it once every 2-3 months.
