If your icemaker isn't producing any ice there is a good chance its because the refrigerator water line is clogged, This is an easy to do-it-yourself job that you can accomplish rather quickly.
Step 1: Prepare the Refrigerator
Unplug the refrigerator from the power supply for safety. Turn off the water supply valve to the line you are working on. Unscrew the water line from the back of the refrigerator and drain it into a bucket.
Step 2: Find the Clog
If you live in an area where there are a lot of minerals in the water, the line can become clogged with these minerals which are the same ones that leave dullness on your bathtub and other fixtures. Sometimes if a line is old the constant usage will cause a buildup of various elements found in water. All of these can clog your water line. Make sure the line isn't pinched or folded and is what's causing it to not flow.
Step 3: Wire
You may be able to see the clog since most lines are semi transparent. Run the wire to the clog and wiggle it around to break up the clog. Turn the water back on slightly and let it all run into the bucket.
