Certain models of KitchenAid brand refrigerators have built-in ice makers with a feature known as Optimice. The Optimice feature was designed to accelerate the normal production of ice by setting the freezer to its lowest temperature setting. This is particularly useful during parties, barbecues or other events where an extra supply of ice is necessary. While the feature is designed for quick and simple use, you may need to do some minor troubleshooting.
Turn on the Optimice feature by pressing a small button labeled "Optimice." This button is located next to the "Max Cooling" button. When the feature is in use, a small light above the button should turn on. If you wish to have increased ice production for only a few hours, you can turn Optimice off by pressing the button again. The light above the button should go off. This will allow the freezer's temperature to rise back to its standard point. It is best to only use Optimice when necessary, because of the increased energy usage.
Set your freezer temperature lower if you want permanently increased ice production. As stated on the KitchenAid Product Help website, the Optimice feature is programmed to work for a 24-hour period, unless you manually turn it off. To have increased ice production for longer than 24 hours, you must set the temperature dial on your refrigerator to a lower number. This will also increase energy expenditure, so it is recommended only for those who require it. Also, certain foods that should remain somewhat soft, such as ice cream, will harden under colder temperatures.
Check the water line if the ice maker stops producing ice altogether. Often, there is a problem with water getting to the refrigerator, so the ice maker is not receiving the water it needs. A good way to check this is to turn on your water dispenser. If no water comes out, there is most likely a problem with the water line into the refrigerator. If it does work, try unplugging the refrigerator for a couple hours and then plug it back in. If it still does not produce ice, there could be mechanical damage, which is covered under most warranties.
