Warning: Before working on your fridge, disconnect it from any electricity sources. If you do not, you risk getting shocked. In addition, do not use the hair dryer in the following steps while standing in or near any water.

Turn off your refrigerator before proceeding. In addition to letting you safely work on the issue, turning off the fridge will also let your frozen supply line to start naturally thawing. If you have any food in your fridge that could spoil easily, transfer it to another fridge, freezer, or icebox temporarily.

With the ice maker emptied, now is the perfect time to clean the ice maker.
Step 3 – Find the Supply Line

Step 4 – Prepare to Catch Water

Step 5 – Thaw the Fill Tube
Next, use a hair dryer on low heat to thaw the fill tube. Make sure you plug the dryer into an outlet that can reach the area you’re working at but is is far away enough from where the fridge’s water may drip. If you see any water spilled nearby, stop the process immediately, unplug the dryer, and clean up the water. Do not stand in any water while using the dryer. Continue this heating process until the supply line feels thawed. Only feel the line with the dryer unplugged and turned off.
Step 6 – Test Your Ice Maker
Finally, you can clean up your area and prepare to test your ice maker. Put your supply line back the way you found it, and put back any items you’ve removed from the fridge. With the water cleaned up, you can now plug your fridge back in to turn on the power. Test your ice maker to see if it works.
If your machine still isn't producing ice, continue troubleshooting your ice maker by checking its valves, bail wire, and more.
