Make sure your ice maker is turned on -- or off, if desired -- at the switch on the upper inside panel of the interior freezer compartment. Moving the toggle switch to "On" keeps ice production apace with the standard fill line. "Off" stops ice production, irrespective of how low the ice level in the reservoir bin gets, and even if the ice bin is entirely empty.
Seat the ice storage bin properly in the door frame so the sensor can properly judge the ice level. Press the bin down firmly, using one hand on each side of the bin, so that it snugs into the door frame and the top of the bin is level.
Check the ice maker ejector arm, feeler arm and/or ice release chute that runs from the reservoir bin to the dispenser for any stuck cubes or built-up ice sheeting. Use a plastic cooking spoon or rubber spatula to clear cubes. Use a moist, hot dish cloth to melt any ice sheeting, and then dry the areas completely.
Refrain from dumping bagged ice, or ice made in another ice machine or tray, into your ice maker. The difference in shape and size may throw off the ice maker's sensor and jam the dispensing mechanisms.
Inspect the ice auger that helps to route ice out of the storage bin through a door dispenser. It can become locked in by melted or lodged ice, which frustrates the ice production system. Remove and completely empty the ice bin. Use a wet, hot dish towel to melt any ice obstructions around the metal, corkscrew-shaped auger. Dry the auger and put the empty bin back firmly into place.
