How to Fix a Leaky GE Icemaker Line

by Cecilia Harsch

The exposed ice maker line on your GE refrigerator runs up the rear of your appliance and through an opening in the wall behind the freezer. Because the nylon line attaches to the exterior wall of the refrigerator, it is more susceptible to sustain accidental damage that can cause the line to leak water onto the floor and reduce or eliminate the production of ice. You can fix a leaky ice maker line by replacing only the damaged area and not the entire line.

Unplug your GE refrigerator’s power cord. Slide the appliance far enough away from the wall until you can comfortably fit behind it. Do not turn off the ice maker water supply yet.

Look for a crack, hole or split in the nylon line. Use a felt-tipped marker or a piece of tape to mark the location of the damage.

Spread some old towels over the floor behind the refrigerator to catch water leaks. Turn off the ice maker's water supply in the wall behind the appliance or beneath the kitchen sink.

Remove the damaged area from the ice maker line by cutting through the line above and below the damage, using sharp utility shears or sharp utility knife. Make straight, 90-degree cuts through the line.

Measure the length of damaged line you removed from the refrigerator. Add 2 to 3 inches to the damaged length of line. Cut a length of 1/4-inch outside diameter (O.D.) ice maker supply tubing equal to your measurement. Ensure to make straight, 90-degree cuts at each end of the supply tubing.

Smooth the line cuts on the back of the GE refrigerator and on the cut piece of tubing, using fine-grit emery cloth to smooth any burrs from the cut edges.

Push plastic 1/4-inch O.D. by 1/4-inch O.D quick-connect couplings onto each end of the length of tubing. Continue to push the couplings onto the tubing until you feel the tubing seat inside the coupling and snap into place. The design of the couplings creates a watertight connection and will not leak.

Slide one coupling over one of the cuts you made in the ice maker line on the back of the refrigerator. Push the coupling onto the line in the same manner as you did when installing them onto the ends of the tubing. Slide the coupling on the opposite end of the tubing over the remaining cut in the ice maker line. Ensure the line seats and the coupling snaps into place.

Secure the couplings to the back of the GE refrigerator, using fiberglass-reinforced tape to stabilize the repaired area. Turn on the ice maker's water supply and plug the refrigerator’s power cord into the wall. Return the GE refrigerator to its original position.
