When your freezer's ice maker is working properly, you'll have ice ready to go at any given time. Unfortunately, you may go to fill up a glass with ice and discover that nothing is coming out of the machine. Before you rush to call a plumber to fix it, you'll want to look at some key parts of the ice maker to make sure that everything is working properly.
How Your Ice Maker Works
In order to understand the reason that your freezer's ice maker is not producing ice, you'll need to have an understanding about how the appliance works.
There should be a cold water line that is run to the area in your kitchen where the freezer is located. There is a separate supply line that connects your freezer to this line, with a valve to shut off the water before it reaches the supply line, and another valve to shut off the water before it enters the freezer. A separate fill tube feeds water directly to the freezer's ice maker.
A bin sits inside your freezer that will catch all the ice cubes that are formed by the ice machine, with a bar that rests on top of the bin. When the ice cubes accumulate and push the bar upward, it triggers the ice maker to stop making ice.
As you can imagine, there are several things in this process that can malfunction and cause ice to not be produced.
Quick Inspection: Fill Tube and Lift Bar
When ice stops being produced, check the bar that rests on top of the bin. It's possible that this bar is stuck in the upright position, which can happen from ice cubes that piled up or water that froze on the mechanism. Get the bar to lay flush with the bin and see if that fixes it.
Next, check the rear fill tube to see if it has frozen. It's possible that the tube has frozen solid, not allowing water into the freezer. Thaw it using your hair dryer.
Advanced Inspection: Supply Line and Valve
Still no ice? Inspect the supply line and valve. Turn the water off, then disconnect the supply line from your freezer. Place a bucket under the water line, and turn on the valve. Is there a constant flow of water? If not, you have an issue with your plumbing. Contact one of the local plumbing services to come out to your home and make repairs to the water line.
