Blocked air vents in the freezer could be the culprit. Kenmore Elite refrigerators have air vents at the top, the middle and the bottom of the freezer. The more food you place in the freezer, the harder it must work to keep all the food frozen. When you pack more and more in the freezer, you are more likely to inadvertently block an air vent. A blocked air vent makes it more difficult for the freezer to maintain the 0-degree Fahrenheit temperature it needs for optimal ice production.
Opening a freezer door often makes it more difficult for ice production to occur, but opening a door is not likely to cause ice to not freeze altogether unless the door is opened consistently for extended periods of time. A damaged or out-of-place gasket that allows warm air to seep into the freezer, however, will impede the production of ice. Examine the rubber gasket around the freezer door to make sure that it is not ripped or torn.
If you have just installed your refrigerator and hooked up the water line to the appliance within the last few hours, you may need to have some more patience before your Kenmore Elite ice maker begins to produce ice. Kenmore recommends you wait 24 hours for the first batch of ice to be produced. The ice maker will not fill until about 72 hours after the refrigerator is installed, according to the manufacturer.
Many Kenmore Elite refrigerators feature a display on the front of the appliance that allows users to see the temperature setting inside the refrigerator and freezer. Your freezer is preset for 0 degrees Fahrenheit, but may need resetting if the temperature has been changed. Press and hold the "Temperature" button for three seconds, then press "Light" to show the freezer temperature. Press "Temperature" to lower the set temperature inside the freezer, then press "Lock" to save the settings.
