How to Troubleshoot Leaky Whirlpool Ice Makers

The ice maker in a Whirlpool refrigerator connects to a water supply line, which is hooked up to a cold water pipe in the kitchen. If the ice maker leaks, isolating the source of the leaking water can help you correct the problem. Internal leaks may be the result of a fill tube out of alignment, while leaks outside the Whirlpool may require more extensive repairs with plumber's tape and common hand tools.

Step 1

Open the Whirlpool freezer door to toggle the ice maker's power switch to the "Off" position.

Step 2

Grasp the fill tube where it emerges from the back wall of the freezer, and insert the tube into the fill cup below it. if the fill tube pops out, water can freeze around the ice maker and inside your freezer, rather than form ice cubes. The fill tube can pop out if the appliance is jostled, such as slamming the freezer door.

Step 3

Pull the Whirlpool away from the wall and unplug the power cord.

Step 4

Turn the knob on the water supply line clockwise to stop the flow of water. The knob may be located near the rear of the Whirlpool or below the kitchen sink where the line taps into the cold water pipe. Shut off the valve in the cold water pipe as well.

Step 5

Unscrew the supply line from the back of the Whirlpool freezer if water leaks from this connection. Unscrew the line from the tap in the side of the cold water pipe if it leaks there.

Step 6

Clean the threads on the end of the supply line with a rag to remove any dirt and grime.

Step 7

Wrap the supply line threads with plumber's tape, which helps seal the connection to prevent leaks. The tape should slightly overlap each revolution around the threads.

Step 8

Reconnect the supply line, and tighten the rotating lock nut on the end with a pair of pliers.

Step 9

Unscrew the cold water and water supply knobs to restore water flow and check for leaks. Tighten the connections with pliers to stop any minor dripping.

Step 10

Plug in the power cord and press the ice maker power switch to the "On" position.
