Finding water puddles under your Whirlpool refrigerator can be frustrating. A common cause is a worn-out drain tube grommet, also called a drain fitting. The good news is that you can replace it yourself with some basic tools and a little time.
This guide explains what the drain fitting does, why it may fail, and how to replace it in about 30 to 45 minutes.
What the Drain Fitting Does and Why Replace It
The drain fitting mounts through the condensation drain hole at the bottom of your Whirlpool refrigerator’s freezer compartment. It seals the opening around the drain tube, keeping the tube in position while allowing water to flow into the pan below.
Over time, the grommet can become brittle, crack, or loosen, which can lead to leaks or poor drainage. Problems can also occur from clogs, freezing temperatures, or physical damage.
Signs of a Faulty Drain Fitting
- Water leaks near the bottom of the refrigerator
- Ice or water buildup in the drain pan
- Stagnant water with an unpleasant odor
- Issues with defrosting or incomplete defrost cycles
Tools and Parts You Will Need
- 1/4-inch nut driver
- Phillips screwdriver
- Flathead screwdriver
- Pliers
- 5/16-inch open-end wrench
- 3/8-inch long socket
- Needle-nose pliers
- Half-round file
- Replacement drain fitting compatible with your refrigerator model
How Long the Repair Takes
Plan for about 30 to 45 minutes. Some freezer components need to be removed to reach the drain fitting, but with the right tools, the process is straightforward.
